Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a document printing apparatus and method.
[0002]
[Prior art]
HTML (hypertext markup language) data is often created without being aware of the paper size and resolution at the time of output, and the data is output using an Internet Explorer (registered trademark) or a Netscape Navigator (registered trademark). When the size is changed, the layout is often defined by relative coordinate values or ratios so that the layout can be changed according to the changed area. When laying out document data described in a structured description language on a physical page, a minimum character size is detected as specific data from the document data, and a scaling factor for laying out the detected specific data is calculated. Then, the document data is subjected to conversion based on the scaling factor so that layout on a physical page is possible (for example, see Patent Document 1).

Reference numeral 106 denotes a display control unit (CRTC) which reads a character pattern data string stored in the RAM 103 and transfers it to the CRT 107. A display device (CRT) 107 receives a character pattern data string from the CRTC 106 and displays it on a display screen.
[0021]
Reference numeral 108 denotes a disk control unit (DKC) that controls access to the external storage device 109. Reference numeral 109 denotes an external storage device such as a floppy (registered trademark) disk device (FD), a hard disk device (HD), or a CD-ROM. The HD stores a character expansion processing program for reading out character pattern data (font data) and font data and converting the data into bitmap data. An application program and related data are supplied from an external storage device such as an FD or a CD-ROM.
[0022]
A network control unit (NTC) 110 controls the operation of the network device (NT) 111. A system bus 112 transfers data between the above-described components.
[0023]
FIG. 3 shows a memory map of the RAM 103 in FIG. The basic I / O program is read into the RAM 103 by a system startup program in the ROM 102. The application program and related data can be executed from the FD or CD-ROM serving as the external storage device 109 by loading the application program and related data from the HD to the RAM 103 once the power is turned on in a state where the application program is installed in the HD. It becomes. It is also possible to directly load the program from the FD or CD-ROM into the RAM 103 and execute the program without installing the program on the HD. In the file server 1, a printer information table, which will be described later, is formed in a related data area.
[0024]
FIG. 4 shows the configuration of the printer 5 of FIG. The printer 5 may be any type such as a laser beam printer, a bubble jet (registered trademark) printer, or a thermal transfer printer, and has a capability of processing XML format data.
[0025]
The printer 5 includes a CPU 211, a ROM 212, a RAM 213, a printer controller (PRTC) 215, a printer engine (PRT) 219, a disk controller (DKC) 216, a hard disk device (HD) 217, and a network controller (NTC). 220 and a network device (NT) 218 are interconnected via a system bus 214.

[0027]
The CPU 211 controls the entire apparatus, and executes various processes necessary for printing according to a program stored in the ROM 212 while using the RAM 213 as a work area or the like. The system bus 214 is a path for exchanging data and control signals between the above components. Note that the ROM 212 stores character pattern data (font data) and the like. Document data, image data, font data, and the like requested to the Web server 2 are downloaded from the Web server 2 and stored in the RAM 213 or the HD 218.
[0028]
The CPU 211 generates character pattern data and image data (bitmap data) from the document data, image data, or font data supplied from the Web server 2 according to a program stored in the ROM 212, and develops the data into a print buffer in the printer controller 215. I do. The printer controller 215 outputs a print control signal generated based on the bitmap data to the printer engine 219.
[0029]
The network controller 220 controls the operation of the network device (NT) 218 when transmitting and receiving data to and from the client personal computers 3 and 4 and the file server 1 via the network 7.
[0030]
FIG. 9 shows the flow of the file conversion process. This processing is divided into processing on the host side and processing on the printer side. The processing on the host side is performed on the Web server 2 in FIG. 1 or performed on the client personal computer 3 or 4. First, a document stored in the XML format or a document stored in the HTML format is read from the file server, and is once converted into data in the XHTML (Extensible Hyper Text Markup Language) format. Then, it is converted into an SVG (Scalable Vector Graphic) that performs an appropriate layout based on the output paper size and resolution according to the flowchart shown in FIG. However, the output of the automatically laid-out document may be different from the user's expectation.
[0031]
At this time, a print image of the automatically laid out document is displayed on the personal computer screen so that the user can change to the desired output, the layout itself can be edited on the display screen, and the edited result is newly displayed. Output to the printer as a simple SVG document. Details of this layout editing will be described later with reference to the flowchart of FIG.
[0032]
The contents of XHTML and SVG are described in the W3C technical report. Basically, XHTML is an extension of the HTML grammar according to the XML format, and is suitable for display. On the other hand, SVG is similar to the grammar of a page description such as PS (Post Script), is XML-extended, and is suitable for an output format. Therefore, HTML or XML document data is once converted into XHTML, and then the output paper size and resolution are obtained, converted into SVG format data, and transferred to a printer that can interpret SVG as an SVG file. By doing so, it becomes possible to properly lay out and output document data written in XML or HTML.
[0033]
FIG. 5 is a flowchart showing an example of a control program stored in the ROM 102 of FIG. 2, which is a control program for converting document data in XHTML format into document data in SVG format. In step S501, a font size serving as a conversion reference is first determined from XHTML format data to be converted. The reference font size is not particularly specified in the XHTML file. Therefore, each browser often defines its own reference font size, but here, a value such as 10 points or 10.5 points is determined as the reference font size for output paper. If the reference font size is written in the XHTML document, the value is determined as the reference font size.
[0034]
In step S502, the entire XHTML document is checked to determine whether there is a table attribute. If there is no attribute of the table, the horizontal area of the size of the predetermined paper or screen to be output becomes the reference size of the horizontal area of the tag as each XHTML element. If table attributes exist, the contents of each table are compared. For example, when the attribute of width matches the <TABLE> element of XHTML, the value becomes the value of the width of the table, and the value having the largest value is selected. If the <TABLE> element has no attribute of width, the horizontal area of the output area is the horizontal area of the table.
[0035]
In step S503, the enlargement / reduction ratio of the output area is calculated from the maximum value of the table obtained in step S502. The calculation method can be obtained from the ratio between the horizontal area of the output area and the maximum horizontal area of the table obtained in step S502. That is, the enlargement / reduction ratio = the horizontal area of the output area / the maximum horizontal area of the table.
[0036]
Then, in step S504 and subsequent steps, the arrangement of each element and the arrangement position of characters in the element are calculated.
[0037]
In step S504, it is first determined whether the target element is a table element, a text element, or an image element. The table elements include <TABLE>, <TR>, <TH>, <TD>, <CAPTION>, <THEAD>, <TFOOT>, <TBODY>, and the like. Text elements include <H1> to <H6>, <P>, <Q>, <BLOCKQUAOTE>, <EM>, <STRONG>, <SUP>, <SUB>, and the like. The image elements include <IMG>, <MAP>, <AREA>, <OBJECT>, <APPLET>, and the like. For the meaning of each element, see http: // www. w3. org / TR / xhtml1 /, and the specification of XHTML and http: // www. w3. See the HTML specification at org / TR / html40 /.
[0038]
If it is determined in step S504 that the target element is an element in the table, the process proceeds to step S505. In step S505, the layout in the table is performed. Details of this processing will be described later with reference to the flowchart of FIG.
[0039]
If it is determined in step S504 that the element is a text element, the process proceeds to step S506. In step S506, an arrangement position for each character in the text element is determined.
[0040]
The text area is divided into a block element and an inline element. Block elements include <H1> to <H6> and <P> elements, and inline elements include <EM> and <STRONG>. This inline element is used as a child element of the block element when emphasizing a character string in the text or changing the color.
[0041]
As a method of arranging the block elements of the text, first, the horizontal area of the text area is determined. Here, the horizontal area of the parent element of the text element is the horizontal area of the text area. For example, if the parent element is <XHTML>, it is the top element, so the horizontal area of the size of the paper or screen to be output is set as the horizontal area of the text area.
[0042]
If the character size is specified by a CSS property that is a W3C specification, if the character size is not specified, the standard size obtained in step S501 is used. The value obtained by multiplying the character size by the enlargement / reduction ratio obtained in step S503 is defined as the character size. At this time, it is checked whether or not the determined character size is set to a value larger than the preset minimum size in step S510, and is stored.
[0043]
Then, the characters are arranged one by one at the determined character size, the characters are folded back beyond the horizontal area, and the continuation is arranged from the beginning of the next line.
[0044]
Then, when all the characters have been arranged, the height of the area is calculated from the number of lines and the font size at that time. At this time, if the size of the line spacing is specified in the CSS property, it follows the size. If not specified, a certain value for the character height is used as a standard value. Set.
[0045]
In addition, as the method of arranging inline elements of text, the end point of the arrangement position of the character immediately before the character string specified inline is used as a reference point, and each character is specified by the character type and character size specified by the element. Are arranged according to the pitch information.
[0046]
On the other hand, if it is determined in step S504 that the element is an image element, the process advances to step S507. In step S507, processing for determining the area of the image element and determining the arrangement position is performed. The size of the image area is determined by multiplying the size of the image area specified in the XHTML document by the enlargement / reduction ratio obtained in step S503. become.
[0047]
Then, in step S508, the contents of each element obtained in steps S505 to 507 are converted into SVG data. At this time, the text element is converted to <tspan> and the image element is converted to <image>. For example, the layout data as shown in FIG. 11 is represented by an XHTML document as shown in FIG. 10, and when it is represented by SVG, it becomes as shown in FIG.
[0048]
In step S509, it is checked whether or not the processing from step S505 to step S507 has been completed for all elements. If the processing has not been completed, the process returns to step S504, and the arrangement position of each element is determined. Is calculated. If the processing has been completed for all elements, the process proceeds to step S510.
[0049]
After the arrangement positions of all elements are calculated in step S510, the entire document is surrounded by <svg> and </ svg>, and a style sheet is defined by a <style> element as necessary to create an svg document. To end.
[0050]
FIG. 6 is a flowchart showing in detail the step S505 in FIG. 5, that is, the processing for calculating the arrangement position of the contents of the table. In step S601, the horizontal area of each cell in the table is calculated. In this calculation method, the sizes of the areas of the cells surrounded by the <TR> elements are summed, and the horizontal area of the table element, which is the parent element, is allocated according to the proportion of each cell. For example, there are three cells as child elements of a table in an XHTML document, and the horizontal area of each cell is 10 for cell 1, 20 for cell 2, 10 for cell 3, and the horizontal area of the table of the parent element. Is 100, the horizontal area of cell 1 is 100 × (10/40) = 25, and similarly, the horizontal area of cell 2 is 50 and the horizontal area of cell 3 is 25.
[0051]
In step S602, the contents of each cell for checking the contents of each cell may be a table, a text, or an image.
[0052]
Each of the determination methods is similar to the method described in step S504, such as <TABLE>, <TR>, <TH>, <TD>, <CAPTION>, <THEAD>, <TFOOT>, <TBODY>, etc. If it is the element, the table element is determined, the process proceeds to step S607, the enlargement / reduction ratio is recalculated, and the process returns to step S601 to process the table element.
[0053]
On the other hand, if elements such as <H1> to <H6>, <P>, <Q>, <BLOCKQUAOTE>, <EM>, <STRONG>, <SUP>, <SUB>, etc., are determined as text elements, The process proceeds to step S603. On the other hand, if the element is <IMG>, <MAP>, <AREA>, <OBJECT>, <APPLET>, or the like, it is determined to be an image, and the process proceeds to step S606.
[0054]
Steps S603 to S605 are cases where it is determined that the element is a text element, and the arrangement position for each character in the text element is determined.
[0055]
The text area is divided into a block element and an inline element. The block elements include <H1> to <H6> and <P> elements. In-line elements include <EM>, <STRONG>, and the like. The inline element is used as a child element of the block element to emphasize a certain character string in the text or change the color.
[0056]
As a method of arranging the block elements of the text, first, the horizontal area of the text area is captured. Here, the horizontal area of the cell determined in step S601 is the horizontal area of the target text.
[0057]
If the character size is specified in the CSS property that is the W3C specification in step S603, the value is calculated in step S501 if the character size is not specified particularly if the value is not specified. The value obtained by multiplying the standard character size by the enlargement / reduction ratio obtained in step S503 or S607 is defined as the character size.
[0058]
Then, it is checked whether or not the size of the character size determined at this time is set to a value larger than the preset minimum size in step S510, and is stored.
[0059]
Then, the characters are arranged one by one at the character size determined in step S604, the characters are folded back beyond the horizontal area, and the continuation is arranged from the beginning of the next line. In addition, as a method of arranging inline elements of text, the end point of the arrangement position of the character immediately before the character string specified inline is used as a reference point, and from there, each character is specified by the character type and character size specified by the element Are arranged according to the pitch information.
[0060]
When all characters have been arranged, the height of the area is calculated from the number of lines and the font size in step S605. At this time, if the size of the line is specified in the CSS property, it follows the size. If not specified, the value of the line height is set as a standard value for the character height. Set.
[0061]
On the other hand, if it is determined in step S602 that the image element is an image element, in step S606, a process of determining the area of the image element and determining the arrangement position is performed. The size of the image area is determined by applying the aspect ratio of the size of the image area specified in the XHTML document to the horizontal area of the cell obtained in step S601 to obtain the height.
[0062]
On the other hand, if it is determined in step S602 that there is another table element in the cell, then in step S607, the size of the cell serving as the parent element of the target table is obtained in step S601. Therefore, it is necessary to convert the size of the table so that it fits in that size. The enlargement / reduction ratio is obtained from the enlargement / reduction ratio = (enlargement / reduction ratio of the table of the parent element) × (horizontal size of the table) ÷ (width of the cell of the parent element).
[0063]
In step S608, it is checked whether or not there is a cell to be further processed. If there is a cell, the process returns to step S602 to perform the same processing. If there is no cell, the processing ends. .
[0064]
FIG. 7 is a flowchart illustrating an example of a layout editing procedure on a screen on which a print image is displayed. In step S701, when the layout of the current SVG document layout image displayed on the screen is to be edited in units of a table, text, or image area, the area is designated with a mouse or the like as shown in FIG. I do.
[0065]
Then, in step S702, it is determined whether the designated area is a table area, a text area, or an image area. If the designated area is a table area, the process proceeds to step S703. If the designated region is an image region, the process proceeds to step S705. If the designated region is a text region, the process proceeds to step S706.
[0066]
In step S703, the designated area is a table, and the area is changed by expanding or reducing the entire area of the table. As a method of changing the area at this time, a method of dragging the mouse may be used, or a method of directly inputting a value on the UI screen may be considered. However, the method of designating the area is not particularly described here.
[0067]
Then, in step S704, the contents of each cell are changed corresponding to the changed area. First, the changed entire area is compared with the entire area before the change to determine an enlargement / reduction ratio, and the enlargement / reduction ratio is reflected in the contents of each cell. For example, when the contents of the cell are text, the same enlargement / reduction ratio is applied to the arrangement position and font size of each character. On the other hand, in the case of an image, the same enlargement / reduction ratio is applied to the vertical and horizontal sizes of the image area.
[0068]
In step S705, the designated area is an image, and the image area is enlarged or reduced, and the vertical and horizontal areas of the image are changed according to the ratio of the original image area to the changed image area. .
[0069]
Steps S706 to S714 are changes relating to the text area. First, in step S706, it is checked whether or not the text area is related to an area change. If the change is related to an area, the process proceeds to step S707, and if the change is related to a font size or font other than the area, the process proceeds to step S708.
[0070]
Step S707 is a case where the text area is changed, and the ratio of the horizontal size of the original text area size and the changed text area size is applied to the font size of each character. Then, since the new font size is defined, the arrangement position of the area is calculated, and the arrangement is performed with the new character size. Then, after the placement is completed, if the placed vertical area is smaller than the changed vertical area, the changed vertical area is used as a new vertical area, and the placed vertical area is changed. If it is larger, the arranged vertical area is used as a new vertical area.
[0071]
Steps S708 to S714 are procedures in a case where the designation of the change is not the designation of the change of the area but directly the designation of the font size, the font, the modification, and the like.
[0072]
In step S708, if the change designation is a font size designation, the process proceeds to step S709, and if the change of the font is designated, the process proceeds to step S7011, where the change designation to the modifier character such as a bold font or an italic font is performed. If there is, the process proceeds to step S713.
[0073]
In step S709, the change is designated as the font size, and the horizontal area of the original text area is not changed. Then, the characters are arranged one by one in the newly designated font size. If it exceeds the horizontal area, the character will wrap there. Then, the enlargement / reduction ratio from the original size to the new designated size at this time is calculated here for use in later step S715. Then, in step S710, after all the character strings are arranged, a vertical area is obtained, and the size of the vertical area is used as a new vertical area of the text area. In step S715, based on the point size changed in step S709, the ratio between the point size before the change and the point size after the change is calculated, and the process of simultaneously changing the characters in other character areas at that ratio is performed. Do. Details of this processing will be described later with reference to the flowchart in FIG.
[0074]
On the other hand, if the change is designated to change the typeface, the horizontal area of the original text area is not changed, but in step S711, the characters are arranged one by one in the font of the newly specified typeface. If it goes beyond the horizontal area, the character will wrap there. Then, in step S712, after all the character strings have been arranged, a vertical region is obtained, and the size of the vertical region becomes a new vertical region of the text region.
[0075]
On the other hand, if the designation of the change is to change the font to bold or italic or to a character without modification as a font modification, the horizontal region in the original text region is not changed, but in step S713 Then, the characters are arranged one by one in the font of the newly designated typeface, and when the characters exceed the horizontal area, the characters are folded back there. Then, in step S714, after arranging all the character strings, a vertical area is obtained, and the size becomes a new vertical area of the text area.
[0076]
In step S716, a new page layout is performed by reflecting the changed area on the entire area. The situation at this time is shown in FIGS. The example of FIG. 13 shows that the table area is specified because the page area is exceeded by enlarging the character of the “heading” of the title, and FIG. 14 adjusts the area of the table area that exceeds the page area in FIG. An example is shown in which the content is stored in one page.
[0077]
Then, in step S717, if the user is satisfied with the current layout, the process ends. If not satisfied, the process returns to step S701 to further specify the same area or another area, and to perform a new area conversion. I will do.

FIG. 15 is a flowchart showing in more detail the process of step S715 of FIG. 7, that is, the process of simultaneously changing the size of characters in another character area. In step S1501, a UI as shown in FIG. 16 is displayed, and the user is allowed to select one of the following three methods (1) to (3). {Circle around (1)} The character size is changed only for the currently targeted block. {Circle around (2)} The character size is changed for all the blocks specified by the tag of the text element such as <P>, <Q>, <BLOCKquote>, and <EM>. {Circle around (3)} When the user specifies an arbitrary tag, the character size is changed for the block specified by the tag. In this case, the user can arbitrarily specify a block to be enlarged or reduced with the current setting. The example of FIG. 16 is a case where the user specifies to perform processing on all text elements.
[0079]
Then, in step S1502, it is determined whether the user has selected only the current block. If there is only the current block, the process ends there. Otherwise, the process proceeds to step S1503.
[0080]
In step S1503, since there is a target block other than the current block, the target block is searched. As a search method, the document is searched from the tag currently targeted, and the search is performed while checking whether the next existing tag is the target tag. In the example of FIG. 16, the processing is applied to all text blocks. Therefore, here, a check is performed to determine whether or not the tag is a text-related tag. When the text block specified in the example of FIG. 16 is selected, it is checked whether or not the specified tag exists, and when the specified tag is found, the block is set as a new target block.
[0081]
In step S1504, if no target tag is found, it is checked whether the processing has been completed for all target tags. If the target tag no longer exists, the process ends there. If the target tag has been found, the process advances to step S1505.
[0082]
In step S1505, as in the case where the processing is performed in step S709, the change is designated as the font size. The processing is performed with the change size ratio being the same as the enlargement / reduction ratio in step S709. Then, the horizontal area of the original text area is not changed, and the characters are arranged one by one at the newly designated font size. When the horizontal area is exceeded, the characters are folded back there.
[0083]
In step S1506, after all the character strings have been arranged, a vertical area is obtained, and the size of the vertical area becomes a new vertical area of the text area.

【The invention's effect】
As described above, according to the present invention, since the configuration is as described above, the area and the font size can be changed after the area is once allocated.
