Operating process is from step S801.Step S802 is the processing that is used for initializing variable.The intermediate code data 303 that obtain by conversion SVG document files 302 are read into variable dlc." fill " is the variable that is used to keep filling employed color that is applied to reproduction instruction, and wherein (r, g, b, a) expression is by the element of the color of RGBA expression.Initialization value is (1.0,1.0,1.0,1.0), that is, and and opaque fully (alpha value is 1.0) white." stroke " is the variable that is used to keep employed color of profile and live width that is applied to reproduction instruction, and wherein (b w) represents the element of color with RGB, and live width (is unit with the pixel) for r, g.Initial value is (0.0,0.0,0.0,1), that is, width is the black line of 1 pixel.
Step S803 is the processing that is used for obtaining from middle code data dlc next command code and operand.The command code and the operand that obtain are stored in respectively among variable " op " and " operand ".Step S804, S806, S809, S811, S813, S816, S821, S823 and S825 are used for determining the type of command code op, make to carry out suitable processing according to each command code.
At step S804, be under the situation of 0 (memonic symbol PageSart) in command code " op ", flow process proceeds to step S805.Otherwise flow process proceeds to step S806.
Step S805 is the preliminary treatment to the variable bmp of storage bitmap data 304.Notice that the element w of bmp represents the width (is unit with the pixel) of data bitmap.For the page width W (mm) in the operand " operand " is converted to bitmap increment (pixel), multiply by operand (W) with output resolution ratio res.The element h of bmp represents the height (is unit with the pixel) of data bitmap.For the high H of page or leaf (mm) in the operand " operand " is converted to bitmap increment (pixel), multiply by operand (H) with output resolution ratio res.The element res of bmp is with the output resolution ratio of PPM (every millimeter pixel) expression printer 313.
Element data[in bmp] be to be used for the storage bitmap array of data, horizontal size is w (pixel), vertical dimension is h (pixel).Data[] element (b a) represents each color of pixel with RGBA for r, g.Data[] the value of element be initialized to current " fill " value, that is, and opaque and white (alpha value is 1.0) fully.The element pre-or-post[of bmp] be used to store color matching before pixel carried out reproducing or reproduce the array of back color matching, its size and array data[] identical.Under the situation of color matching, " pre " is held as described value before having carried out reproducing, and carrying out reproducing under the situation of back color matching, and " post " is held.Initial value is post.After this was handled, flow process was returned step S803.
Command code op is under the situation of 1 (memonic symbol PageEnd) in step S806, calls the processing that printer output defines at step S807, and flow process finishes at step S808.Otherwise flow process proceeds to step S809.The processing of this printer output definition will describe with reference to Figure 14 in the back.
At step S809, be under the situation of 2 (memonic symbol Fill) at command code op, flow process proceeds to step S810.Otherwise flow process proceeds to step S811.
Step S810 is that the renewal of variable " fill " is handled.In operand " operand " regulation color (R, G, B, A) be stored in variable " fill " element (r, g, b, a) in.In case this processing finishes, flow process is returned step S803.
At step S811, be under the situation of 3 (memonic symbol Stroke) at command code op, flow process proceeds to step S812.Otherwise flow process proceeds to step S813.
Step S812 is that the renewal of variable " stroke " is handled.In operand " operand " regulation color (R, G, B) and live width (W) be stored in variable " stroke " element (r, g, b, w) in.At this moment, for the increment of operand (mm) being converted to the increment (pixel) of bitmap, multiply by W (mm) with output resolution ratio bmp.res.In case this processing finishes, flow process is returned step S803.
At step S813, be under the situation of 4 (memonic symbol PathStart) at command code op, flow process proceeds to step S814.Otherwise flow process proceeds to step S816 from step S815.
Step S814 be to the variable that is used for reproducing in the path " path[] and the preliminary treatment of " cursor ".This path[] be the array that is used for the coordinate figure of store path.Path[] element (x y) is the coordinate figure of the coordinate of delegated path, and its increment is a pixel.This cursor is the variable that is used to store current reproduction position, and (x is the coordinate figure that the position is reproduced in expression y) to element, and its increment also is a pixel in this case.In case this processing finishes, flow process is just returned step S803.
At step S816, be under the situation of 5 (memonic symbol PathEnd) at command code op, flow process advances to step S817.Otherwise flow process advances to step S821.
Step S817 is used for determining that whether operand " operand " is 1 processing.Under it was 1 situation, flow process advanced to step S818, otherwise flow process advances to step S819.
Step S818 is the closed path reproduction processes.Command code 7 (memonic symbol PathLineTo) is inserted at the current reading location of variable dlc.When operand is the starting position of current path (it is path[0]), carry out conversion, so path[0 from bitmap increment (pixel) to operand increment (mm)] by divided by output resolution ratio bmp.res.In addition, command code 5 (memonic symbol PathEnd) also is inserted into, to carry out the path end process once more.Do not need the closed path reproduction processes specifically, so operand is 0.In case this processing finishes, flow process is returned step S803 from step S827.
Step S819 is the processing that is used to need to determine whether the path filling.The value of the variable " cursor " of the current reproduction position in expression path and as the variable path[0 of starting position, path] value compare, under the situation that they equate, determine that then the path is closed, thereby need to fill, so flow process advances to step S820.Otherwise flow process is returned step S803 from step S827.
Step S820 is used to call the processing of the path being filled the processing of definition.The processing that definition is filled in this path will describe with reference to Figure 11 in the back.
At step S821, be under the situation of 6 (memonic symbol PathMoveTo) at command code op, flow process proceeds to step S822.Otherwise flow process advances to step S823.
Step S822 is that the renewal of variable of the current reproduction position in expression path is handled.The coordinate figure of in operand operand, stipulating (x, y) be stored in variable cursor element (x, y) in.At this moment, for the increment of this operand (mm) being converted to the increment (pixel) of bitmap, (X Y) multiply by output resolution ratio bmp.res to operand.In case this processing finishes, flow process is just returned step S803 from step S827.
At step S823, be under the situation of 7 (memonic symbol PathLineTo) at command code op, flow process proceeds to step S824.Otherwise flow process advances to step S825.
Step S824 is the processing that is used for reproducing the straight line of data bitmap bmp.Starting point is that (x, y), it is the current reproduction position in path to cursor.End point be by the coordinate figure of operand operand regulation (X, Y), but for the increment of operand (mm) being converted to the increment (pixel) of bitmap, bmp.data[operand (X, Y)] multiply by output resolution ratio bmp.res.For profile, use the color (RGB) and the live width (pixel) of variable " stroke ".The coordinate figure of reproduced straight line (pixel) is added in variable path[], the coordinate figure of Tian Jiaing (end points of line) is stored among the variable cursor at last.In case this processing finishes, flow process is just returned step S803 from step S827.
At step S825, be under the situation of 8 (memonic symbol PathArcTo) at command code op, flow process proceeds to step S826.Otherwise, to handle and skipped, flow process turns back to step S803 from step S827, and this is because do not have this situation in intermediate code regulation shown in Figure 7.
Step S826 is the processing that is used for reproducing the arc of data bitmap bmp.Starting point is that (x, y), it is the current reproduction position in path to cursor.Central point be by the coordinate figure of operand operand regulation (X, Y), but for the increment of operand (mm) being converted to the increment (pixel) of bitmap, bmp.data[operand (X, Y)] multiply by output resolution ratio bmp.res.Angle be by the angle D of operand operand regulation (°).For profile, use the color (RGB) and the live width (pixel) of variable " stroke ".Reproduced coordinate figure (is unit with the pixel) is added in variable path[], the coordinate figure of Tian Jiaing is stored in the variable " cursor " at last.In case this processing finishes, flow process is just returned step S803 from step S827.
With reference to Fig. 8,15 and 16 illustrate an example of the operation of reconstructors 310 after a while.
Below with reference to Figure 11 path padding is described.Figure 11 is used to be illustrated as the flow chart that the processing operation of definition is filled in the path.The processing of this definition is called from the step S820 of flow chart shown in Figure 9.
Step S901 begins path padding, bmp wherein, and path and fill are the parameters when the processing of this definition is called.Parameter b mp is initialised at the step S805 of the flow chart of Fig. 9 and Figure 10, and has and at step S820, S824, the identical value of upgrading among the S826 of variable bmp.The step S814 of parameter p ath in the flow chart of Fig. 9 and Figure 10 is initialised, and has and at step S824, the identical value of upgrading among the S825 of variable path.The step S802 of parameter f ill in the flow chart of Fig. 9 and Figure 10 is initialised, and has and the identical value of upgrading in step S810 of variable fill.
Step S902 is that initialization of variable is handled.Here, " coord " be used for from the upper left side to lower right sweep bitmap data b mp.data[] time keep the variable of coordinate figure, wherein (x, y) expression is the coordinate figure of increment with the pixel.Initial value is (0,0), the upper left side of expression data bitmap bmp.data.The flow chart of Figure 11 is a circulation, and wherein variable coord is a cyclic variable.
Step S903 is the whether processing in the path of being represented by variable path of coordinate figure that is used for determining expression variable coord.Only determine that at step S819 variable path is a closed path, thereby always just call this under the situation of closed path at this by path of variable " path " expression and handle, and can carry out whether being in determining in this path about coordinate figure arbitrarily at step S820.Under the situation of determining to be in this path, flow process advances to step S904.If not in the path, then flow process advances to step S907.
Step S904 is whether the alpha value of the color that is used for determining that variable fill represents is the processing of 1.0 (opaque fully).At alpha value is under the situation of 1.0 (opaque fully), and then determining does not need alpha blended, and flow process advances to step S905.Not (that is, having transparency) under 1.0 the situation at alpha value, then determine to carry out alpha blended, and flow process advances to step S906.
Step S905 is to be that the filling that (opaque fully) carries out under 1.0 the situation is handled at alpha value.In this case, do not need alpha blended, thereby replace at data bitmap bmp.data[with the color of variable fill regulation] in the color at coordinate position coord place.
Step S906 calls processing for the processing of alpha blended definition what alpha value was not that (that is, having transparency) carries out under 1.0 the situation.For the return value of the processing of alpha blended definition be follow the color of alpha blended (RGBA) and whether reproduced before color matching or reproduce the sign (pre or post) of back color matching.As a result, data bitmap bmp.data[] value and at the sign bmp.pre_or_post[at coordinate position coord place] value that is returned replaces.Processing for the alpha blended definition describes with reference to Figure 12 and 13 after a while.
Step S907 is a circular treatment to S910.Step S907 makes the horizontal direction value coord.x of variable coord increase by 1 processing.Step S908 is the horizontal direction value coord.x that is used for the determining variable coord size of the data bitmap that equals horizontal direction that whether become, i.e. the processing of bmp.w.Under the situation that they equate, flow process advances to step S909, if unequal, then flow process is returned step S903.
Step S909 is that the horizontal direction value coord.x that is used for initializing variable coord is 0, and makes the vertical direction value coord.y of variable coord increase by 1 processing.Step S910 is the vertical direction value coord.y that is used for the determining variable coord size of the data bitmap that equals vertical direction that whether become, i.e. the processing of bmp.h.Under the situation that they equate, flow process advances to step S911, if unequal, then flow process is returned step S903.
Step S911 finishes.Though the return value of undefined processing is as the processed data bitmap bmp.data[of parameter b mp] be updated.
Below with reference to Figure 12 and 13 explanation alpha blended operations.Figure 12 represents to verify the configuration of result database 312.
At this, Reference numeral 1001 expressions constitute the row of the record of checking result database 312, the data during 1002 expression storages are expert at.The RGBA that Reference numeral 1003 and 1004 storages will be carried out the color of alpha blended expresses.
Row 1005,1006 and 1007 storages are used for discerning input configuration file 305, and the ID of printer profile 307 and reproduction intention 308 is so that reconstructor 310 use CMM 311.The color that row 1008 storage conducts obtain with the result of the alpha blended of RGBA expression, color matching was still reproduced back color matching (value of " pre " or " post ") before row 1009 storages had been reproduced.
Figure 13 is the flow chart of expression for the processing of alpha blended definition, and the step S906 of the processing of this definition from flow chart shown in Figure 11 is called.In the processing of this definition, use 3 kinds of color matching functions of CMM 311, i.e. CMM.gm, CMM.cc and CMM.1ab.
CMM.gm carries out Color Gamut Mapping.Parameter (prof2 intent) is color assignment " color " for color, prof1, configuration file " profil1 ", and configuration file " prof2 ", and reproduce intention " intent ".The function of CMM.gm is the color " color " according to the colour gamut of " intent " mapping " prof1 " expression of the colour gamut of " prof2 " expression, and the color of the colour gamut of conduct " prof1 " expression is returned.
CMM.cc carries out color conversion.(color, prof1 prof2) are color assignment " color " to parameter, configuration file " profil1 " and configuration file " prof2 ".The function of CMM.cc is that the color " color " of the colour gamut of " prof1 " expression is converted to the colour gamut of " prof2 " expression, and does not shine upon.And the color of the colour gamut of conduct " prof2 " expression is returned.Its prerequisite is that the color of being stipulated by " color " is in the colour gamut of " prof2 " expression.
CMM.1ab proceeds to L *a *b *The conversion of value.L *a *b *Color space is a kind of uniform color space, and it was drafted by CIE (Commission Internationale de1 ' Eclairage) in 1976, according to luminance index L *And chromaticity index a *And b *Expression.(color prof) is color assignment " color " and configuration file " prof " to parameter.The function of CMM.Lab is that the color " color " of colour gamut that prof is represented converts L to *a *b *Value is also returned.
Step S1101 is the beginning of alpha blended.Parameter " color1 " and " color2 " are the parameters when the processing of call definition.Parameter " color1 " be initialised at Fig. 9 and step S805 shown in Figure 10 and at the step S905 of Figure 11, that S906 or other step are updated, at data bitmap bmp.data[] in the color value at arbitrary coordinate place.Parameter " color2 " is the color value of the variable " fill " that is initialised at Fig. 9 and step S802 shown in Figure 10 and be updated at step S810.
Step S1102 is the initialization process that is used for variable." return " is the variable that is used to keep return value, and wherein (b a) represents the element of color to element with RGBA for r, g.The color matching or the variable of reproduction back color matching before element pre_or_post has been used to keep carrying out reproduce, and retention value " pre " or value " post "." inputProf " is the variable that is used to keep import the content of configuration file 306." printerProf " is the variable that is used to keep the content of printer profile 307." intent " is the variable that is used to keep reproduce the content of intention 308.
Step S1103 is used for verifying the processing of being verified results whether in 312 registrations of checking result database.Search for as shown in figure 12 checking result database of its configuration, to search the record of registration, variable color1 wherein, variable color2, variable i nputProf, variable printerProf, and variable i ntent is as parameter.Find at first wherein that color1 is matched with row 1003, color2 is matched with row 1004, and inputProf is matched with row 1005, and PrinterProf is matched with row 1006, and intent is matched with the record of row 1007.As the value of the row 1008 of this found record of Search Results and row 1009 be stored in separately variable " return " (b is a) and (pre_or_post) for r, g.At step S1103, determine whether to find record, under the situation that finds record, flow process advances to step S1112, and end process.Under the situation of found record not, flow process advances to step S1104.Because this configuration, whether the evaluation result that the SVG document of input provides the true reappearance of color is being registered under the situation about verifying in the result database 312 about reproducing one of preceding color matching/reproductions back color matching, this result can be used immediately.
Step S1104 is carrying out being used to obtain L under the situation of color matching before the reproduction *a *b *The processing of value.At first, use the CMM.gm function of CMM311 that the colour gamut of intention " intent " from the input Color Gamut Mapping to printer 313 reproduced in the value utilization of the value of parameter c olor1 and parameter c olor2, and the result is stored among variable preInpt1 and the preInput2.The input colour gamut is represented that by inputProf the colour gamut of printer 313 is represented by printerProf.
Then, carry out the mixed processing between the value of the value of variable preInput1 and variable preInput2, and the result is stored among the variable preRender.By to the value of preInput1 (r, g, b, a) and the value of preInput2 (b a) carries out following calculating and carries out described mixed processing for r, g.
preRender.r＝preInput1.r×preInput1.a+preInput2.r×preInput2.a×(1-preInput1.a)
preRender.g＝preInput1.g×preInput1.a+preInput2.g×preInput2.a×(1-preInput1.a)
preRender.b＝preInput1.b×preInput1.a+preInput2.b×preInput2.a×(1-preInput1.a)
preRender.a＝preInput1.a+preInput2.a×(1-preInput1.a)
At last, the CMM.cc function of use CMM 311 from importing the colour gamut that colour gamut (being represented by inputProf) is transformed into printer 313, stores the value of mixing resultant preRender among the variable prePrinter then.In addition, use the CMM.1ab function of CMM 311 value of prePrinter to be converted to the L that will be stored among the variable preLab *a *b *Value.
Step S1105 is used to obtain L under the situation of having carried out reproduction back color matching *a *b *The processing of value.At first, carry out the mixed processing between the value of the value of parameter c olor1 and parameter c olor2, and the result is stored among the variable postRender.By to the value of color1 (r, g, b, a) and the value of color2 (b a) carries out following calculating and carries out described mixed processing for r, g.
preRender.r＝color1.r×color1.a+color2.r×color2.a×(1-color1.a)
preRender.g＝color1.g×color1.a+color2.g×color2.a×(1-color1.a)
preRender.b＝color1.b×color1.a+color2.b×color2.a×(1-color1.a)
preRender.a＝color1.a+color2.a×(1-color1.a)
Then, use the CMM.gm functional utilization of CMM 311 to reproduce intention " intent ", the value of mixing resultant preRender is mapped to the colour gamut (representing) of printer 313 from input colour gamut (being represented by inputProf) by printerProf.The result is stored among the variable postInput.At last, from importing the colour gamut (being represented by printerProf) that colour gamut (being represented by inputProf) is transformed into printer 313, the result is stored among the variable postPrinter CMM.cc function of use CMM 311 then the value of mixing resultant postInput.In addition, use the CMM.1ab function of CMM 311 value of postPrinter to be converted to the L that will be stored among the variable postLab *a *b *Value.
Step S1106 is the L that is used for the logic of acquisition input colour gamut (being represented by inputProf) *a *b *The processing of value.At first carry out the mixed processing between the value of the value of parameter c olor1 and parameter c olor2, and the result is stored among the variable tRender.Mix in the mode identical with step S1105.Then, use the CMM.1ab function of CMM 311 value of mixing resultant tRender to be converted to the L that will be stored among the variable tLab *a *b *Value.
Step S1107 is used for obtaining at L *a *b *CIE L between value preLab and tLab and postLab and the tLab *a *b *The processing of colour-difference (CIE 1976).Aberration Δ E between preLab and tLab PreAnd the aberration Δ E between postLab and tLab PostBy to preLab value (L *, a *, b *), postLab value (L *, a *, b *) and tLab value (L *, a *, b *) carry out following calculating and calculate.
ΔE pre 2＝(preLab.L *-tLab.L *) 2+(preLab.a *-tLab.a *) 2+(preLab.b *-tLab.b *) 2
ΔE post 2＝(postLab.L *-tLab.L *) 2+(postLab.a *-tLab.a *) 2+(postLab.b *-tLab.b *) 2
Result of calculation is stored among variable deltaE_Pre and the deltaE_Post separately.At step S1108, aberration deltaE_Pre and aberration deltaE_Post are compared.Under the less situation of the value of variable deltaE_Pre, flow process advances to step S1109, otherwise flow process advances to step S1110.
Step S1109 is the processing of carrying out under following situation: the value of the situation of color matching relatively approaches logical value (that is, under the situation of relatively generation deltaE_Pre＜deltaE_Post of step S1108) before being used to reproduce.Keep the reproduction result's of input colour gamut (representing) the value of preRender by inputProf be stored in variable " return " (r, g, b, a) in, value " pre " is stored among (pre_or_post) of variable " return ".
Step S1110 is the processing of carrying out under the following situation: the value of the situation of color matching relatively approaches logical value (that is, under the situation that relatively produces deltaE_Pre 〉=deltaE_Post of step S1108) after being used to reproduce.Keep the reproduction result's of input colour gamut (representing) the value of postRender by inputProf be stored in variable " return " (r, g, b, a) in, value " post " is stored among (pre_or_post) of variable " return ".
Step S1111 is the processing that is used in checking result database 312 registration checking results.Record is registered in the checking result database, the configuration of this checking result database as shown in figure 12, variable color1 wherein, variable color2, variable i nputProf, variable printerProf, variable i nten and variable return are as parameter.In other words, color1 is registered in the row 1003 of checking result database, and color2 is registered in 1004 in the checking result database.In addition, inputProf is registered in the row 1005 of checking result database, and printerProf is registered in the row 1006 of checking result database, and intent is registered in the row 1007 of checking result database.In addition, (b a) is registered in the row 1008 of checking result database return, and return (pre_or_post) is registered in the row 1009 of checking result database for r, g.
Because above-mentioned configuration, can make about following both evaluation:
(1) in the input colour gamut, in the result who utilizes alpha blended to reproduce and after alpha blended, carry out difference between the result of color matching, and
(2) in the input colour gamut, in the result who utilizes alpha blended to reproduce and after color matching, carry out difference between the result of alpha blended.
One with less difference is registered in the checking result database.Thereby, requiring under the same conditions (color value, input configuration file, output profiles, reproduce intention) under the situation about handling,, can obtain the result fast and need not calculate once more by from the checking result database, reading the result of registration.
Finish in step S1112 flow process.The value of variable " return " is returned as return value.
The output function of printer is described below with reference to Figure 14.Figure 14 is the flow chart of explanation about the operation of the processing of printer output definition.The processing of this definition is called from the step S807 of the flow chart of Fig. 9.
Step S1201 begins the processing of this definition.Parameter b mp has with initialization in the step S805 of Fig. 9, flow chart shown in Figure 10 and at step S820,824 variable bmp identical values reproduced with S826.
Step S1202 is that initialization of variable is handled.Wherein " coord " is that wherein (x is y) with pixel increment denotation coordination value at the variable that is used to keep coordinate figure from the upper left side during to lower right sweep bitmap data b mp.data.Flowchart configuration shown in Figure 20 is for being a kind of circular treatment, and wherein variable " coord " is once (primary) cyclic variable." inputProf " is the variable that is used to keep import the content of configuration file 305." printerProf " is the variable that is used to keep the content of printer profile 307." intent " is the variable that is used to keep reproduce the content of intention 308.Oputputbmp[] be the array that is used to be kept for the data bitmap of printer output, its size and bmp.data[] measure-alike.
Step S1203 is used for obtaining by from bmp.data[] and bmp.pre_or_post[] variable " coord " and the processing of the data bitmap of the coordinate figure of the value representation of " pre " or " post ".The value that is obtained is respectively stored among variable " data " and " pre_or_post ".
Step S1204 is used for determining whether variable pre_or_post has the processing of value " pre ".Carrying out for pixel under the situation that alpha blended reproduces, at the variable bmp.pre_or_post[of the step S805 value of being initialized to post] have the value pre or the post that store therein at step S906.Under the situation of other reproduction, basic void value is stored.Thereby, in step S1204 YES remain genuine unique situation be pixel be carried out reproduce before color matching and alpha blended situation about reproducing.In this case, flow process advances to step S1206.Otherwise flow process advances to step S1205.
Step S1205 is the CMM.gm function that is used to use CMM311, according to reproducing intention " intent " the processing of pixel data (data bitmap) from the input Color Gamut Mapping to the colour gamut of printer 313.The result is overwritten on the variable " data ".
At step S1206, the color value of variable " data " has been mapped to the colour gamut (being represented by printerProf) of printer 313.The CMM.cc function of use CMM 311 is transformed into variable " data " colour gamut (being represented by printerProf) of printer 313 from input colour gamut (being represented by inputProf).The result is stored at printer output data bitmap outputbmp[] in the coordinate position of variable " coord " expression.
Step S1207 is a circular treatment to step S1210.Step S1207 is used to make the horizontal direction value coord.x of variable coord to increase by one processing.Step S1208 is whether the horizontal direction value coord.x that is used for determining variable coord becomes and equal that the size of data bitmap is the processing of bmp.w on the horizontal direction.Under the situation that they equate, flow process advances to step S1209, if unequal, then flow process is returned step S1203.
Step S1209 is used to make the vertical direction value coord.y of variable coord to increase by one processing.Step S1210 is whether the vertical direction value coord.y that is used for determining variable coord becomes and equal that the size of data bitmap is the processing of bmp.h on the vertical direction.Under the situation that they equate, flow process advances to step S1211, if unequal, then flow process is returned step S1203.
Step S1211 is used for sending the printer output data bitmap outputbmp[that produces to the controller 314 of printer 313] processing.Printer 313 is stored the data bitmap of reception as data bitmap 315 in RAM 209, and exports to carry out according to data bitmap 315 control Printer Engines 212.
Step S1212 finishes.There is not return value.
At last, will use intermediate code data shown in Figure 8, an example of the operation of reconstructors 310 will be described with reference to Figure 15 and 16.Figure 15 and Figure 16 are illustrated in after the flow process shown in Fig. 9 to 11 and 13, and reconstructor 310 reproduces the mode of intermediate code data shown in Figure 8.
The intermediate code data are read into variable dlc at step S802.Variable " fill " be initialized to fill (r, g, b, a)=(1.0,1.0,1.0,1.0).Variable " stroke " be initialized to stroke (r, g, b, w)=(0.0,0.0,0.0,1).
In first command code of dlc (PageStart), be initialised at step S804 and S805 variable bmp.Suppose that printer resolution is 300dpi (dots per inch), the resolution that converts PPM (every millimeter pixel) to is 11.811PPM, because 1 inch is 25.4mm.Printer resolution after using this to change obtains bmp.w=210.0 * 11.811=2480.31 ≌ 2480 (decimal system rounds), bmp.h=297.0 * 11.811=3507.867 ≌ 3507 (decimal system rounds), wherein bmp.res=11.811 (PPM).In addition, array bmp.data[] and bmp.pre_or_post[] size be 2480 * 3507=844856.Bmp.data[] be initialized to the fill that is initialised at step S802 (r, g, b, a)=(1.0,1.0,1.0,1.0).Pre_or_post[] be initialized to " post ".
In second command code (Fill) of dlc, be updated at step S809 and S810 variable fill.At this, and fill (r, g, b, a)=(1.0,1.0,0.0,0.7).
In the 3rd command code (Stroke) of dlc, be updated at step S811 and S812 variable " stroke ".At this moment, obtain live width by making 2.0 operand multiply by resolution bmp.res, it equals 2.0 * 11.811=23.622 ≌ 23 (decimal system rounds), so as to produce stroke (r, g, b, w)=(0.0,0.0,1.0,23).
At the 4th operand (PathStart) of dlc, be initialised at step S813 and S814 variable " path[] " and " cursor ".Here do not carry out the processing relevant with operand, thus cursor (x, y)=(0,0).
In the 5th command code (PathMoveTo) of dlc, be updated at step S821 and S822 variable " cursor ".This is obtained by making coordinate figure multiply by resolution bmp.res, i.e. cursor.x=80.0 * 11.811=944.88 ≌ 944 (decimal system rounds), and cursor.y=30.0 * 11.811=354.33 ≌ 354 (decimal system rounds).
Utilize the 6th command code (PathArc) of dlc, arc 1301 is reproduced.Starting point 1302 is currencys of variable " cursor ", and it is (944,354).Multiply by resolution bmp.res by (80.0,80.0) that make operand and obtain central point 1303, it is 80.0 * 11.811=944.88 ≌ 944 (decimal system rounds), so as to producing (944,944), and is 360 degree according to this operand angle.Profile is blue, and it is the currency of variable " stroke ", and live width is 23 pixels.Be added to variable path[at starting point 1302 beginning, the coordinate of describing and turn back to the profile of starting point 1302 clockwise along arc 1304].
Utilize the 7th command code (PathEnd) of dlc, operand is not 1, does not therefore carry out the processing of step S818.Be maintained at path[] in starting point and end point all by 1302 the expression (944,354), thereby, determine that at step S819 this is a closed path.This calls the processing (Figure 11) that definition is filled in the path at step S820.
Fill in the processing in the path, whether each pixel coordinate of determining data bitmap is at path[] in, if at path[] in, then carry out handling according to the colouring of " fill ".According to the currency of variable " fill ", promptly (b a)=(1.0,1.0,0.0,0.7) fills for r, g.Alpha value is not 1.0, thereby calls the processing (Figure 13) of alpha blended definition at step S906.
Suppose at step S1103 and in the checking result database, do not find record, then carry out alpha blended to S1111 and handle at step S1104.Wherein, at bmp.data[] initialized value (1.0,1.0,1.0,1.0) and fill (1.0,1.0,0.0,0.7) between mix.Color matching or reproduce the back color matching and select before reproducing according to input configuration file 305, printer profile 307 and the content of reproducing intention 308, but supposition here selected to reproduce before color matching.Also suppose the data bitmap bmp.data[of the point in profile 1301 that obtains as mixing resultant] value be (0.9,0.2,0.2,1.0), and the supposition pre_or_post[] value be " pre ".Such reproduction result as shown in figure 15.
In the 8th command code (Fill) of dlc, be updated at step S809 and S810 variable " fill ".Here, and fill (r, g, b, a)=(1.0,0.0,0.0,0.5).
In the 9th command code (PathStart) of dlc, be initialised at step S813 and step S814 variable " path[] " and " cursor ".Do not carry out the processing relevant herein with operand, thus cursor (x, y)=(0,0).
In the tenth command code (PathMoveTo) of dlc, be updated at step S821 and S822 variable " cursor ".This is obtained by making coordinate figure multiply by resolution bmp.res, i.e. cursor.x=140.0 * 11.811=1653.54 ≌ 1653 (decimal system rounds), and cursor.y=30.0 * 11.811=354.33 ≌ 354 (decimal system rounds).
Utilize the 11 command code (PathArc) of dlc, arc 1304 is reproduced.Starting point 1305 is currencys of variable " cursor ", and it is (1653,354).By making (140.0 of operand, 80.0) multiply by resolution bmp.res and obtain central point 1306, it is 140.0 * 11.811=1653.54 ≌ 1653 (decimal system rounds) and 80.0 * 11.811=944.88 ≌ 944 (decimal system rounds), so as to producing (1653,944), and according to this operand, angle is 360 degree.Profile is blue, and it is the currency of variable " stroke ", and live width is 23 pixels.Be added to variable path[at starting point 1305 beginning, the coordinate of describing and turn back to the profile of starting point 1305 clockwise along arc 1304].
Utilize the 12 command code (PathEnd) of dlc, operand is not 1, does not therefore carry out the processing of step S818.Be maintained at path[] in starting point and end point all by 1305 the expression (1653,354), thereby, determine that at step S819 this is a closed path.This calls the processing (Figure 11) that definition is filled in the path at step S820.
In fill to handle in the path, whether the coordinate of each pixel of determining data bitmap was at path[] in, if at path[] in, then carry out handling according to the colouring of " fill ".According to the currency of variable " fill ", promptly (b a)=(1.0,0.0,0.0,0.5) fills for r, g.Alpha value is not 1.0, thereby calls the processing (Figure 13) of alpha blended definition at step S906.
Suppose for this situation and also in the checking result database, do not find record, then carry out alpha blended to S1111 and handle at step S1104 at step S1103.At this, for the profile overlapping areas 1308 of arc 1301, at bmp.data[] value (0.0,0.0,1.0,1.0) and fill (1.0,0.0,0.0,0.5) between mix.For with the inside overlapping areas 1307 of arc 1301, at bmp.data[] value (0.9,0.2,0.2,1.0) and fill (1.0,0.0,0.0,0.5) between mix.
For remaining zone 1306, at bmp.data[] initial value (1.0,1.0,1.0,1.0) and fill (1.0,0.0,0.0,0.7) between mix.Color matching is handled or is reproduced the back color matching and handle according to input configuration file 305, printer profile 307 and the content of reproducing intention 308 and select before reproducing, but supposition has here selected to reproduce the back color matching.
About mixing resultant, with the profile overlapping areas 1308 of arc 1301, data bitmap bmp.data[] value be (0.5,0.0,0.5,1.0).And, with the inside overlapping areas 1307 of arc 1301, data bitmap bmp.data[] value be (0.95,0.1,0.1,1.0).At remaining regional data bitmap bmp.data[] value be (1.0,0.5,0.5,1.0).Pre_or_post[] value all be " post ".Like this, reproduce the result as shown in figure 16.Then, for the 13 to the 17 command code of dlc, carry out identical processing.
At the 18 command code (PageEnd), call the processing (Figure 14) of printer output definition at step S807.
At this moment, for pre_or_post[] have the pixel of value " pre ", for example the pixel in the zone in the overlapping arc 1301 of another arc of discord 1304 is mapped to the printer colour gamut at step S1205.Then, at step S1206, proceed to the conversion of printer colour gamut for all pixels.At step S1211, Zhi Bei printer output bitmap is sent to the controller 314 of printer 313 like this, so as to obtaining final output.
Though Fig. 4 represents intermediate code data 303 and data bitmap 304 and 305 and is maintained among the RAM, can carry out such configuration, wherein data are stored in permanent memory for example in file, the database etc.In addition, also it is contemplated that such configuration, the intermediate code data that wherein are used for identical PDL document are by high-speed cache, and are used to processing subsequently.
In addition, though Fig. 7 represents the regulation of intermediate code, the regulation of operable intermediate code is not limited thereto.For example, increment is not limited to millimeter, can be other selectable increment, or both combinations.Path description can be that Bessel's curve, elliptic arc maybe can be with other optional paths of mathematical expression.Colouring is not limited to single color, can allow complicated colouring, for example paintbrush, image, gradient etc.Color is not limited to RGB or RGBA, can allow by the color profile regulation, by the device color assignment, by the color code regulation, etc.In addition, it only is an example that command code is used the integer of 1 byte and the configuration of the floating number that operand uses 2 bytes, can use other coding method.Perhaps, be sent in the configuration of printer 103 PDL that can use printer 103 to explain in intermediate code.
In addition, though Figure 11 represents to use general-purpose algorithm to scan whole bitmap, and determine whether each coordinate is included in the situation in the path of parameter " path " expression, the another kind of method that can expect is, extract the coordinate in the path that is included in parameter " path " expression in advance, and carry out reproduction about these coordinates.
In addition, Figure 13 represents to use CIE L *a *b *Aberration (CIE 1976) still also can use other aberration, for example CIE Δ E as the situation of aberration 94(CIE 1994) or CIE Δ E 2000(CIE 2000).
Thereby, according to the present invention, under the situation that need carry out the alpha blended reproduction to the PDL document, can more suitably carry out color matching.And, determine the PDL document for example be used among SVG etc. alpha blended drawing instruction, extract this instruction and when reproducing, the colouring information of stipulating can accurately carry out color matching (S906 of Figure 11) with the colouring information of printing equipment in PDL.Specifically, can control, so that checking:
(1) before the reproduction that relates to alpha blended, carries out color matching, still
(2) after the reproduction that relates to alpha blended, carry out color matching,
Be more accurate, and select more accurate a kind of.Thereby, when relating to the reproduction of alpha blended, can realize that the color to wanting processed PDL data is real color matching.And using the record of storage in checking result database 312 is efficiently, because this does not need to calculate the repeatedly like combinations of color matching and reproduction.

The overview of the operation of reconstructor 1711 is described below with reference to Figure 22 and Figure 23.Figure 22 and Figure 23 represent that reconstructor 1711 reproduces intermediate code data 1703 to produce the operational flowchart of data bitmap 1704, and described data bitmap is sent to the controller 314 of printer 313.
Operating process is from step S1801.Step S1802 is the processing that is used for initializing variable.The intermediate code data 1703 that obtain by conversion SVG document files 1702 are read into variable dlc." fill " is the variable that is used to keep filling used color that is applied to reproduction instruction, and wherein (r, g, b, a) expression is by the element of the color of RGBA expression.Initial value is (1.0,1.0,1.0,1.0), that is, and and opaque fully (alpha value is 1.0) white." stroke " is the variable that is used to keep used color of profile and live width that is applied to reproduction instruction, and wherein (b w) represents the element of color with RGB, and live width (is unit with the pixel) for r, g.Initial value is (0.0,0.0,0.0,1), that is, width is the black line of 1 pixel." grad " is the variable that the linear gradient that is used to keep to be applied to reproduction instruction is filled the gradient vector that will use.At this, (x1 is y1) with (x2 y2) is the coordinate (pixel) of starting point and end point respectively, and (r1, g1 is b1) with (r2, g2 b2) utilize RGB to express the color of representing gray scale (gradation) starting point and end point respectively.There is not initial value." paint " is used to determine to be to use solid color " fill " also to be to use the variable of linear gradient " grad ", and keeps the value of " fill " or " grad ".Initial value is " fill ".
Step S1803 is the processing that is used for obtaining from middle code data dlc next command code and operand.The command code and the operand that obtain are stored in respectively among variable " op " and " operand ".Step S1804, S1806, S1809, S1811, S1813, S1815, S1818, S1825, S1827 and S1829 are used for determining the type of command code op, make to carry out suitable processing corresponding to each command code.
At step S1804, be under the situation of 0 (memonic symbol PageSart) in command code " op ", flow process proceeds to step S1805.Otherwise flow process proceeds to step S1806.
Step S1805 is used to carry out various initialized processing.At first, " inputProf " is the variable that is used to keep import the content of configuration file 305." printerProf " is the variable that is used to keep the content of printer profile 307." intent " is the variable that is used to keep reproduce the content of intention 308." bmp " is the variable that is used for storage bitmap data 1704.Notice that the element w of bmp represents the width (pixel) of data bitmap.Page width W (mm) in operand " operand " multiply by output resolution ratio res, and thereby is converted into bitmap increment (pixel).The element h of Bmp represents the height (pixel) of data bitmap.The high H of page or leaf (mm) in operand " operand " multiply by output resolution ratio res, and thereby is converted into bitmap increment (pixel).Element res in bmp is with the output resolution ratio of PPM (every millimeter pixel) expression printer 313.
Element among the bmp " pdef " storage is reproduced preceding color matching or is reproduced the back color matching.Be that " post " is held as this value under 1 the situation at the sign F of operand " operand ", otherwise " pre " is held as this value.
Element data[in bmp] be to be used for the storage bitmap array of data, its horizontal size is w (pixel), vertical dimension is h (pixel).Data[] element (r, g, b, a) expression represent each color of pixel with RGBA.Data[] the value of element be initialized to current " fill " value, that is, and the white of opaque fully (alpha value is 1.0).Value at variable " pdef " is under the situation of color matching before " pre " thereby regulation are reproduced, and is reproducing intention " intent " afterwards, uses the CMM.gm function the colour gamut of the value of fill from the input Color Gamut Mapping to printer 313, and the value of Storage Mapping.The element pre-or-post[of bmp] be used for storing color matching before each pixel of bitmap carried out reproducing or reproduce the array of back color matching, its size and array data[] identical.Under the situation of color matching, " pre " is held as described value before having carried out reproducing, and carrying out reproducing under the situation of back color matching, and " post " is held.Initial value is the value of variable pdef.After this was handled, flow process was returned step S1803.
Op is under the situation of 1 (memonic symbol PageEnd) in step S1806 command code, calls the processing that printer output defines at step S1807, and flow process finishes at step S1808.Otherwise flow process proceeds to step S1809.The processing of this printer output definition will describe with reference to Figure 28 in the back.
At step S1809, be under the situation of 2 (memonic symbol Fill) at command code op, flow process proceeds to step S1810.Otherwise flow process proceeds to step S1811.
Step S1810 is that the renewal of variable " Fill " is handled.In operand " operand " regulation color (R, G, B, A) be stored in variable " fill " element (r, g, b, a) in.In addition, the value of variable " paint " is set to " fill ", thereby uses solid color to fill in colouring subsequently.In case this processing finishes, flow process is returned step S1803.
At step S1811, be under the situation of 3 (memonic symbol GradLinear) at command code op, flow process proceeds to step S1812.Otherwise flow process proceeds to step S1813.
Step S1812 is that the renewal of variable " grad " is handled.In operand " operand " regulation the gray scale vector (X1, Y1, X2, Y2, R1, G1, B1, R2, G2, B2) be stored in variable " grad " element (x1, y1, x2, y2, r1, g1, b1, r2, g2, b2) in.In addition, the value of variable " paint " is set to " grad ", thereby uses gradient in colouring subsequently.In case this processing finishes, flow process is returned step S1803.
At step S1813, be under the situation of 4 (memonic symbol Stroke) at command code op, flow process proceeds to step S1814.Otherwise flow process advances to step S1815.
Step S1814 is that the renewal of variable " stroke " is handled.In operand " operand " regulation color (R, G, B) and live width (W) be stored in variable " stroke " element (r, g, b, w) in.At this moment, for the increment of operand (mm) being converted to the increment (pixel) of bitmap, bmp.res multiply by W with output resolution ratio.In case this processing finishes, flow process is returned step S1803.
At step S1815, be under the situation of 5 (memonic symbol PathStart) at command code op, flow process advances to step S1816.Otherwise flow process advances to step S1818 from step S1817.
Step S1816 is the preliminary treatment of the variable that is used for reproducing in the path " path[] " and " cursor ".This path[] be the array that is used for the coordinate figure of store path.Path[] element (x y) is the coordinate figure of the coordinate of delegated path, and its increment is a pixel.This cursor is used to store the variable that the position is reproduced in current path, and wherein (x is the coordinate figure that the position is reproduced in expression y) to element, and increment also is a pixel in this case.In case this processing finishes, program is just returned step S1803.
At step S1818, be under the situation of 6 (memonic symbol PathEnd) at command code op, flow process advances to step S1819.Otherwise flow process advances to step S1825.
Step S1819 is whether the sign F that is used for determining operand " operand " is 1 processing.Be that flow process advances to step S1820 under 1 the situation, otherwise flow process advance to step S1821.
Step S1820 is the closed path reproduction processes.Command code 8 (memonic symbol PathLineTo) is inserted at the current reading location of variable dlc.When operand is as path[0] the starting position of current path the time, carry out conversion, so path[0 from bitmap increment (pixel) to operand increment (mm)] by divided by output resolution ratio bmp.res.In addition, command code 6 (memonic symbol PathEnd) also is inserted into, to carry out the path end process once more.Do not need the closed path reproduction processes specifically, so operand is 0.In case this processing finishes, flow process is returned step S1803 from step S1831.
Step S1821 is the processing that is used to need to determine whether the path filling.The value of the variable " cursor " of the current reproduction position in expression path and as the variable path[0 of starting position, path] value compare, under the situation that they equate, determine that then the path is closed, thereby need to fill, so flow process advances to step S1822.Otherwise flow process is returned step S1803 from step S1831.
Step S1822 is used to determine the processing that is to use solid color also to be to use gradient to paint.Value at variable paint is under the situation of fill, determines to use the solid color colouring, and flow process advances to step S1823, otherwise, just to determine to use the gradient colouring, flow process advances to step S1824.
Step S1823 is the processing that is used to call to the processing of monochromatic path colouring definition.The processing of this path colouring definition will describe with reference to Figure 24 in the back.

Below with reference to Figure 24 path padding is described.Figure 24 is used to be illustrated as the flow chart that the processing operation of definition is filled in the path.The processing of definition is called from the step S1823 of flow chart shown in Figure 23.
Step S1901 begins path padding, and bmp wherein, path and fill are the parameters when the processing of definition is called.Parameter b mp is initialised at the step S1805 of the flow chart of Figure 22 and Figure 23, and has and at step S1823, S1824, the identical value of upgrading among S1828 and the S1830 of variable bmp.The step S1816 of parameter " path " in the flow chart of Figure 22 and Figure 23 is initialised, and has and at step S1828, the identical value of upgrading among the S1830 of variable path.Parameter f ill is initialised at the step S1802 of Figure 22, and has and the identical value of upgrading in step S1810 of variable fill.
Step S1902 is that initialization of variable is handled.At this, " coord " be used for from the upper left side to lower right sweep bitmap data b mp.data[] time keep the variable of coordinate figure, wherein (x y) with the pixel is the incremental representation coordinate figure.Initial value is (0,0), the upper left side of expression data bitmap bmp.data.The flow chart of Figure 24 is a circulation, and wherein variable coord is a cyclic variable.
Step S1903 be used for determining expression variable coord coordinate figure whether by the processing in the path of variable " path " expression.Only determine that at step S1821 variable " path " is a closed path thereby always just calls this under the situation of closed path at this by path of variable " path " expression and handle, and can carry out whether being in determining in the path about coordinate figure arbitrarily.Under the situation of determining to be in this path, flow process advances to step S1904.If not in the path, then flow process advances to step S1907.
Step S1904 is used for determining whether the alpha value of the color of variable " fill " expression is the processing of 1.0 (opaque fully).At alpha value is under the situation of 1.0 (opaque fully), and then determining does not need alpha blended, and flow process advances to step S1905.At alpha value is not under the situation of 1.0 (promptly having transparency), then determine to carry out alpha blended, and flow process advances to step S1906.
Step S1905 is that the alpha value at variable " fill " is that the filling of carrying out under the situation of 1.0 (opaque fully) is handled.In this case, do not need alpha blended, thereby replace at data bitmap bmp.data[with the color of variable " fill " regulation] in the color of coordinate position coord.
Step S1906 is that the alpha value at variable " fill " is not the processing of carrying out under the situation of 1.0 (promptly having transparency) to the processing of alpha blended definition of calling.To the return value of the processing of alpha blended definition, follow alpha blended color (RGBA) so and close carried out reproducing before color matching or reproduce after the sign of color matching (pre or post).As a result, data bitmap bmp.data[] value and at the sign bmp.pre_or_post of coordinate position coord] value that is returned replaces.Processing to the alpha blended definition describes with reference to Figure 25 after a while.

Step S2004 is the reproduction processes of carrying out under the situation of color matching before reproducing.At first, follow and reproduce intention " intent ", the CMM.gm function of using CMM 312 is the colour gamut of the value of parameter c olor2 from the input Color Gamut Mapping to printer 313, and the result is stored among the parameter c olor2 once more.Value at parameter p re_or_post is under the situation of " pre ", the data bitmap at this coordinate place has been carried out Color Gamut Mapping, does not therefore have the required processing of parameter c olor1.Then, color1 and the value of color2 after mapping are mixed, and the result be stored in variable return (r, g, b, a) in.At last, value " pre " is stored among the variable return.pre_or_post.Mixed processing can utilize following formula from the value of color1 (r, g, b, a) and the value of color2 (b a) calculates for r, g.
return.r＝color1.r×color1.a×(1-color2.a)+color2.r×color2.a
return.g＝color1.g×color1.a×(1-color2.a)+color2.g×color2.a
return.b＝color1.b×color1.a×(1-color2.a)+color2.b×color2.a
return.a＝color1.a×(1-color2.a)+color2.a
Step S2005 is the reproduction processes of carrying out under the situation of reproducing the back color matching.The value of the value of variable color1 and variable color2 is mixed, the result be stored in variable return (r, g, b, a) in, and " post " be stored among the variable return.pre_or_post.Identical among this mixed processing and the step S2004.
