Description
Technical field
The present invention relates to a kind of keyline layout method and system, relate in particular to a kind of mixed keyline layout method and system.
Background technology
In the plate-making process, the content (comprising image, literal, lines etc.) of the page need be combined on request, form the page; Perhaps need the book size according to printing machine, the requirement that cuts and bind, with a plurality of different page amalgamations together, make printing surface.This content with the page is grouped together and forms the complete page, perhaps a plurality of different pages is grouped together on request, and the process that constitutes printing surface is called layout.The size of layout is determined by the size of printing format and printing sheets.
The layout mode is divided into traditional layout mode and computing machine layout mode.Traditional layout mode is by the manual imposition of manually finishing.Manual imposition is very high to the requirement of operative skill and experience, needs to consume great amount of manpower and material resources, financial resources and time, and may problems such as register trouble occur at final printing stage.
Along with the widespread use of digital printing, produced computing machine layout mode, i.e. digitizing layout mode.Common digitizing layout mode has two kinds, i.e. layout before layout and the rasterisation behind the rasterisation.So-called rasterisation is meant the process that a vector graphics (as straight line, circle) is converted to a series of picture elements.Respectively these two kinds of layout modes are introduced below.
(1) layout behind the rasterisation
Need the little page or leaf page of layout to have various Format Types, for example the suffix descriptive language page (PostScript) but the portable document format page (PDF), the PCL page (PCL), the Tagged Image File (TIF) Format page (TIFF) etc.As shown in Figure 1, layout behind the rasterisation is the little page or leaf page with described various Format Types, uses the corresponding raster image processor of Format Type with this little page or leaf page to carry out rasterisation, generates corresponding data with rasterized; Then described data with rasterized is carried out other layout of dot matrix level, generate the final big version space of a whole page.Wherein, raster image processor is RIP, and it is a kind ofly page-description language to be converted to raster image and at the processor of the enterprising line output of output device (as film setter, computer direct platemaking machine, printer).
Behind rasterisation in this layout mode of layout, what raster image processor received is the form of some standards, tiff format for example, so layout is to the Format Type of the page-description language of input without limits behind the rasterisation.But owing to be subjected to the influence of printing format size and resource for computer system, data with rasterized tends to bigger, can't leave in the computer system memory always.So, just must earlier the data with rasterized of each page-description language file be write on the disk, form disk file and preserve.In layout, will read in internal memory with the data with rasterized of disk file storage before again, carry out layout, form the final big version space of a whole page, and the big edition space of a whole page is delivered to the output device output of rear end.Such processing mode is elapsed time relatively, thereby has just reduced the layout efficient of layout behind the rasterisation.
(2) layout before the rasterisation
Layout is a plurality of little page or leaf page of the same Format Type (for example PostScript form) that will need layout before the rasterisation as shown in Figure 2, at first synthesize the big version page of a justifying, the raster image processor by same format type (for example PostScript form) carries out rasterisation then; The data with rasterized of the little page or leaf page of described same format type (for example PostScript form) is stored in the same storage space of calculator memory or hard disk; At last read data with rasterized in the described storage space by raster image processor, assembling generates the final big version space of a whole page.
Because layout is that the big version page is carried out rasterisation before the rasterisation, and the data behind the described big version page rasterisation are stored on calculator memory or the disk together.Therefore, the read-write operation repeatedly to calculator memory or disk has been avoided in layout before the rasterisation, has improved the layout treatment effeciency to a certain extent.
But, layout before the common rasterisation, raster image processor is more single for the call format of the little page or leaf page, and for example layout requires the page description file form of the little page or leaf page all to be the PostScript file or all to be pdf document etc. before the rasterisation.In addition, because layout before the rasterisation is to need the little page or leaf page of layout once to synthesize the big version page of a justifying each, carry out rasterization process then.Therefore in rasterization process, if find raster image processor some little page or leaf page is wherein explained incorrect situation, the layout system just can not make an explanation to the little page or leaf page of makeing mistakes separately again, but need make an explanation again to the whole big version page.Will make before the rasterisation layout correctness and predictablely reduce greatly so like this, thereby reduce layout efficient.

As shown in Figure 3 be the process flow diagram of mixed keyline layout method of the present invention.The mixed keyline layout here is meant the process that the little page or leaf of the various Format Types page to input (as the little page or leaf page of the little page or leaf page of the little page or leaf page of PostScript language description, PDF type, PCL Format Type, tiff format type etc.) carries out layout.
This method mainly comprises the steps:
(S1) explanation module, Knockdown block, shared memory cell are set respectively; Wherein said explanation module corresponds respectively to a kind of little page or leaf page of Format Type at least for the explanation module of the explanation module of two kinds of different-format types and every kind of Format Type;
(S2) be explanation module setting and distribution layout parameter, and be that explanation module distributes the little page or leaf page;
(S3) explanation module carries out grammar explanation according to the layout parameter that is provided with to the little page or leaf page, generates intermediate file;
(S4) described Knockdown block assembling intermediate file generates big version typeface dot-matrix;
(S5) big version typeface dot-matrix is stored in the shared memory cell.
In above-mentioned steps (S1), the explanation module that is provided with is the explanation module of at least two kinds of different-format types, the explanation module of every kind of Format Type is the little page or leaf page of corresponding a kind of Format Type respectively, explanation module as the corresponding PS Format Type of the little page or leaf page of PostScript Format Type, the explanation module of the corresponding PDF type of the little page or leaf page of PDF type, the explanation module of the corresponding PCL Format Type of the explanation module of PCL Format Type, the explanation module of the corresponding tiff format type of the little page or leaf page of tiff format type etc.
In the above-mentioned steps, form final big version typeface dot-matrix and will be somebody's turn to do the process that big version typeface dot-matrix stores shared memory cell into, without limits the Format Type of each little page of page of input.Method of the present invention is carried out grammar explanation by each explanation module to the little page or leaf page of various Format Types, generate each intermediate file, therefore the layout system was in the process of a rasterisation before this had just broken through rasterisation, can only carry out grammar explanation to the little page or leaf page of same Format Type, and can not be simultaneously the little page or leaf page of multiple Format Type be carried out the restriction of grammar explanation, thereby improve the efficient of mixed keyline layout, improved the compatibility and the extendability of mixed keyline layout.
In above-mentioned steps (S2), described layout parameter comprises: the little page or leaf page output information of big version layout parameter and various Format Types.
Described big version layout parameter comprises: big version type page size, and output device resolution, the output device position is dark, and whether output device supports special look.
The little page or leaf page output information of described various Format Types is meant the positional information of the little page or leaf page of various Format Types at the big version space of a whole page; Described positional information obtains by a transformation matrix of coordinates.
In page description file, described all pels based on coordinate system be referred to as user coordinate system system (User Coordinate System), and this user coordinate system and output device are irrelevant.May there be X in the little page or leaf page with respect to the coordinate system of the big version space of a whole page, the skew of Y direction, and this offset operation can pass through transformation matrix CTM (Transformation Matrix) to be realized.The form of the mathematical description of transformation matrix is as follows:
[1 0 0 1 tx ty]
Wherein, tx, ty are exactly under user coordinate system, the little page or leaf page with respect under the big version space of a whole page coordinate system at x, the translational movement that the y direction need be carried out.
Need the account form of the position coordinates of the little page or leaf page in the big version space of a whole page of various Format Types of layout as follows:
x’＝x+tx
y’＝y+ty
Wherein, x, y are the coordinate figures in the little page or leaf page, and x ', y ' are the coordinate figures in the big version space of a whole page.Coordinate figure in the little page or leaf page is known, the coordinate figure of this little page or leaf page in the big version space of a whole page can be provided with by the user, so just can calculate very easily under user coordinate system, little page of page with respect under the big edition space of a whole page coordinate system at x, the translational movement tx that the y direction need be carried out, ty.
When the little page or leaf page of various Format Types, big version layout information are sent to each explanation module, the transformation matrix of the little page or leaf page correspondence of various Format Types is sent simultaneously, thereby can guarantee that each little page or leaf page obtains correct position in the big version space of a whole page.
The detailed process for the little page or leaf of each explanation module distribution page described in the step (S2) is: be the explanation module of every kind of Format Type, distribute and the corresponding little page or leaf page of its Format Type, for example distribute the little page or leaf page of PDF, distribute little page or leaf page of PS form or the like for the PS explanation module for the PDF explanation module.Like this, just can carry out grammar explanation to the little page or leaf page of the multiple Format Type of input.
In above-mentioned steps (S3), by grammar explanation, the content of pages of the little page or leaf page can be decomposed into independently a series of element figure object, as the literal object, Drawing Object, image object, gradient object and their assembly.
Described intermediate file, can be understood as can be assembled a kind of file that is similar to the page-description language form of module identification.Intermediate file is the little page or leaf page that is independent of original various Format Types, that is to say, this intermediate file has comprised the information of the original little page or leaf page that its corresponding explanation module imports.
In addition, behind the intact little page or leaf page of the every explanation of each explanation module, export the included explain information of this little page or leaf page, and after all little page or leaf pages explanations were finished, output was explained and is finished control signal.
According to the explain information of each explanation module output, determine the assembling parameter, generate the assembling control command, and will assemble parameter and assemble control command and send to described Knockdown block.
Described explain information comprises look face number and the look face title that the little page or leaf page of various Format Types comprises respectively.
Described assembling parameter comprises: high, the total segments of section of each assembling section, and every section every look face needs memory size, and every section needs memory size altogether.
According to the resource for computer system situation, calculate each assembling parameter.The size of each assembling section is mainly determined according to the size of computing machine free memory.
In above-mentioned (S4), Knockdown block assembling intermediate file, the detailed process that generates big version typeface dot-matrix comprises;
(S41) calculate each height H s that assembles section:
Hs＝M/X/n
Wherein, Hs is the height of each assembling section, unit: pixel;
M is the size of computing machine free physical memory, unit: megabyte;
X is the width of the big version of final physical space of a whole page directions X, unit: pixel;
N is the look face number that the big version of the final physical space of a whole page comprises.
(S42) the assembling control module is according to the height of each assembling section in the segmentation assembling that calculates, physics type page size in conjunction with the big version space of a whole page, can further calculate: segments altogether, every section required memory size of every look face, and the size of the section of needs internal memory altogether.These CALCULATION OF PARAMETERS methods once are described below.
Segments Ns altogether:
When Ns=H/Hs is the Hs integral multiple as H;
Ns=H/Hs+1 other.
Wherein, Ns is total hop count;
H is the height of big version space of a whole page physics type page, unit: pixel;
Hs is the height of each assembling section, unit: pixel.
Every section every look face needs memory size Ms:
Ms＝(W*B+7)/8
Wherein, Ms is that every section every look face needs memory size, unit: byte;
B is that the output device position is dark, and general value is: 1 or 8;
W is the width of big version space of a whole page physics type page, unit: pixel.
Every section needs memory size Mt altogether:
Mt＝Ms*n
Wherein, Mt is every section size that needs internal memory altogether, unit: byte;
Ms is that every section every look face needs memory size, unit: byte;
N is the look face number that the big version of the final physical space of a whole page comprises.
After calculating, applying for distributing memory headroom, earlier memory headroom is carried out initialization.This initialized work is only carried out once before Knockdown block is assembled, and does not carry out initialized work in the operating process afterwards.
In the described step (S4), assemble each intermediate file, it should be noted that the only responsible assembling of Knockdown block in the process of the big version of generation typeface dot-matrix, calculator memory is not carried out any initialized operation at Knockdown block.Therefore, when the class description language file of the one little page of page in back stored in the storage unit, the intermediate file of the little page or leaf page of storage before can not be capped, thus the assembling result's of other the little page or leaf page before guaranteeing validity.
As further optimization, Knockdown block carry out segmentation when assembling can be only to having the little page or leaf page of friendship to carry out the assembling of dot matrix with current assembling section, thereby avoided in the assembling process repeatedly scanning work, improve the efficient of mixed keyline layout.
In the assembling process, Knockdown block successively the intermediate file of the corresponding little page or leaf page in the assembling section is assembled, and the result of every section assembling adopts the mode of sharing dot matrix according to described assembling parameter.This has also just been avoided behind the rasterisation needing constantly carry out repeatedly the operation of writable computer internal memory or hard disk to the data with rasterized of each little page or leaf page in the layout system.
The implication of sharing dot matrix is meant, the result of every section assembling, promptly dot array data all will leave in the shared memory cell in advance in the internal memory of its appointment, be that each big version typeface dot-matrix is in storing shared memory cell into the time, according to the positional alignment of each little page or leaf page in the big version space of a whole page of having determined.The big version typeface dot-matrix that to store at last outputs on the output device.
Described step (S5) also comprises: after generating big version typeface dot-matrix, also can read each intermediate file and generate the low resolution preview graph.By this step, can judge early whether each explanation module is correct to the explanation of each little page or leaf page, and then before rasterisation, can make an explanation again to explaining the incorrect little page or leaf page, the layout mode can only further improve the layout efficient of mixed keyline layout system to the whole big edition situation that the page makes an explanation before having avoided rasterisation after certain little page or leaf explanation makes mistakes.
Simultaneously, in the prior art,, be respectively to finish by the explanation module of PDF raster image processor and the explanation module of PostScript raster image processor to the explanation of pdf document and PostScript tab file.Owing to lack necessary connection between the explanation module of two kinds of different raster image processors, like this, traditional rasterization process mode can't combine both functions, adds the PostScript mark when also just can't realize the pdf document rasterisation.
But, according to the method for the invention, owing to can make an explanation to pdf document and PostScript tab file simultaneously, and the intermediate file of generation consolidation form, therefore, when explanation module makes an explanation, just can join the PostScript mark in the pdf document.
Corresponding with mixed keyline layout method of the present invention, the present invention also provides a kind of system of mixed keyline layout.
