Hyper Text Markup Language
e). And from there Figure 9
SVG (Sca) that performs an appropriate layout according to the output paper size and resolution according to the flowchart shown in FIG.
(Layer Vector Graphic).

Then, a case occurs where the output of the automatically laid out document is different from the user's intention. 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 the output to a desired output, the layout situation 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 the layout editing at this time will be described with reference to the flowchart shown in FIG.

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 processing.

On the other hand, SVG is a PS (Pod made by Adobe).
It is similar to the grammar of a page description such as (stScript), is XML-extended, and is suitable for an output format. Therefore, the HTML or XML document data is once converted to XHTML, and then the output paper size and resolution are obtained and converted to SVG format data.
It is transferred as an SVG file to a printer that can be interpreted by SVG. By doing so, XML and H
Document data written in TML can be appropriately laid out and output.

FIG. 6 is a diagram for explaining the example of the document in the XHTML format shown in FIG. 5, and FIG. 7 is a diagram for explaining the layout structure of the example of the document in the XHTML format shown in FIG. FIG. 8 is a diagram illustrating an example of an SVG conversion list of the document in the XHTML format illustrated in FIG. 7.

Next, according to the flowchart shown in FIG. 9, the detailed flow of the process of converting the document data in the XHTML format into the document data (document) including the image in the SVG format in the information processing apparatus according to the present invention will be described. Do.

FIG. 9 is a flowchart showing an example of a first data processing procedure in the information processing apparatus according to the present invention. (5-1) to (5-11) indicate each step.

First, in step (5-1), a font size serving as a conversion reference is obtained from XHTML format data as a conversion source. The reference font size is not specified in the XHTML file.

Accordingly, each browser often determines its own reference font size, but here, 10 points or 1 point is set as the reference font size for output paper.
Determine a value such as 0.5 point.

When the reference font size is described in the XHTML document, the value is determined as the reference font size.

Next, in step (5-2), X
The entire HTML document is checked to see if there is any table attribute, and the maximum horizontal size table is extracted. If there is no table attribute, the horizontal area of the paper or screen size desired to be output is set to each XHTML. The size is a reference size of the horizontal area of the tag as an element.

On the other hand, if there is a table attribute, the contents of each table are compared. For example, if the <HTML> element of XHTML has an attribute of width, the value becomes the value of the width of the table, and the value having the largest value is selected.

On the other hand, width is added to the <TABLE> element.
If there is no attribute, the horizontal area of the output area becomes the horizontal area of the table.

Next, in step (5-3), the enlargement / reduction ratio of the output area is calculated (calculated) from the maximum value of the table extracted in step (5-2). 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 (5-2).
That is, the enlargement / reduction ratio = the horizontal area of the output area / the maximum horizontal area of the table.

In step (5-4) and subsequent steps, the layout of each element and the layout of characters in the element are calculated. Determines whether the element is a text element or an image element.

Here, as an example of a table element, <TA
BLE>, <TR>, <TH>, <TD>, <CAPT
ION>, <THEAD>, <TFOOOT>, <TBO
DY> and the like. As text elements, <Hl>-<
H6>, <P>, <Q>, <BLOCKQUAOTE>,
<EM>, <STRONG>, <SUP>, <SUB>
Etc.

Then, as an image element, <IMG
>, <MAP>, <AREA>, <OBJECT>, <
APPLET> and the like. Regarding the meaning of each element, an address on the WWW, for example, http: // WW
W. W3. org / TR / xhtml1 / and the specification of XHTML and http: // www. w
3. org / TR / htm140 / in accordance with the HTML specifications.

If it is determined that the target element is a table element, the process proceeds to step (5-5). If it is determined that the target element is a text element, the process proceeds to step (5-6). The process proceeds to step (5-7) if it is determined that the element is an image element.

Then, in step (5-5),
This is the case when it is determined that the element is a table element, and the arrangement in the table is performed. For details of the process here,
Since the details will be described with reference to the flowchart shown in FIG. 10, the description here will be omitted.

On the other hand, in step (5-6), when it is determined that the element is a text element, the arrangement position for each character in the text element is determined. The text area is divided into a block element and an inline element. The block elements include <Hl> to <H
6> and <P> elements. Further, examples of the inline element include <EM>, <STRONG>, and the like. further,
The inline element is used as a child element of the block element to emphasize a character string in the text or change the color.

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.

Then, regarding the size of the character,
If it is specified in the CSS property that is the specification of 3C, the value is changed to the standard character size obtained in step (5-1) if the character size is not specified. On the other hand, a value obtained by multiplying the enlargement / reduction ratio obtained in step (5-3) is set as the character size.

The size of the character size determined at this time is checked in a step (5-10) to be described later to see whether it is set to a value larger than a preset minimum size. deep. And
Characters are arranged one by one at the determined character size, and characters are wrapped beyond the horizontal area.
Continues from the beginning of the next line. 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 is specified in the CSS property, it follows that size. Unless otherwise specified, the value of the line height is set as a standard value for the character height. I do.

As a method of arranging the inline element of the text, the end point of the arrangement position of the character immediately before the character string designated inline is set as a reference point, and the character type and the character size designated by the element from there. Is arranged according to the pitch information of each character.

On the other hand, in step (5-7), when it is determined that the image element is an element, the process of determining the area of the image element and determining the arrangement position is performed. Note that in the present embodiment, the method of determining the size of the image area is as follows: the size of the image area is determined by the step (5-) with respect to the size specified in the XHTML document.
It becomes the size of the area multiplied by the enlargement / reduction ratio obtained in 3).

Then, in step (5-8), the contents of each element obtained in steps (5-5) to (5-7) are converted into SVG data. At this time, the text element is <tspan> and the image element is <image
e>.

Thus, for example, the data of the layout shown in FIG. 7 is represented by the XHTML document shown in FIG. 6, and when it is represented by SVG, it becomes as shown in FIG.

Next, in step (5-9), it is checked whether or not the processing from step (5-5) to step (5-7) has been completed for all the elements. If it is determined that there is no such element, the process returns to step (5-4) to calculate the arrangement position of each element.

On the other hand, if it is determined in step (5-9) that the processing has been completed for all elements, the arrangement positions of all elements have been calculated in step (5-10). Later, the entire document is converted to <svg> and </ svg
Enclose the style sheet as necessary.
> SVG conversion defined by the element is performed, and the creation process of the svg document ends.

FIG. 10 is a flowchart showing an example of the second data processing procedure in the information processing apparatus according to the present invention. In FIG. 10, the calculation of the arrangement position of the contents of the table in step (5-5) shown in FIG. It corresponds to the detailed procedure to be performed. (6-1) to (6-8) indicate each step.

First, in step (6-1), the horizontal area of each cell in the table is calculated. In the present embodiment, the horizontal area of each cell is calculated by adding the size of the area of each cell surrounded by the <TR> element and dividing the horizontal area of the table element, which is the parent element, by the ratio of each cell. Assign according to.

For example, there are three cells as child elements of a table in an XHTML document, and the horizontal area of each cell is “1” for cell 1, “20” for cell 2,
Cell 3 is “10” and the horizontal area of the parent element table is “1”.
00 ”, the horizontal area of cell 1 is 100 × (10 /
40) = 25, and similarly, the horizontal area of cell 2 is “5
0 ", and the horizontal area of cell 3 is" 25 ".

Next, in step (6-2), the content of each cell to be checked is a table, a text, or an image. There are cases.

Each determination method is similar to the method described in step (5-4) shown in FIG.
BLE>, <TR>, <TH>, <TD>, <CAPT
ION>, <THEAD>, <TFOOOT>, <TBO
If it is an element such as DY>, it is determined as a table element, the process proceeds to step (6-7), the enlargement / reduction ratio is recalculated, and the process returns to step (6-1) to recursively process the table element. Do.

Step (6-7) is a case where it is further determined that the cell is a table element.
Since the size of the cell serving as the parent element of the target table has been obtained in step (6-1), it is necessary to convert the size of the table so as to fit within the size. Then, the calculation method at that time is: enlargement / reduction ratio = magnification and reduction ratio of the table of the parent element × horizontal size of the table / width of the cell of the parent element.

On the other hand, in step (6-2), <Hl> to
<H6>, <P>, <Q>, <BLOCKQUAOTE
>, <EM>, <STRONG>, <SUP>, <SU
If the element is an element such as B>, it is determined to be a text element, and the process proceeds to step (6-3), where <IMG>, <MAP>,
If the element is an element such as <AREA>, <OBJECT>, <APPLET> or the like, it is determined to be an image, and step (6-6)
Proceed to.

Then, in steps (6-3) to (6-5), when it is determined that the element is a text element, the arrangement position for each character in the text element is determined.

The text area is divided into a block element and an inline element.
There are <Hl> to <H6>, <P> elements and the like, and 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 character string in the text or change the color.

As a method of arranging the block elements of the text, first, the horizontal area of the text area is fetched. Here, the horizontal area of the cell determined in step (6-1) is the horizontal area of the target text.

First, in step (6-3), if the size of a character is specified by a CSS property that is a W3C specification, no particular character size is specified for that value. In this case, a value obtained by multiplying the standard character size obtained in step (5-1) shown in FIG. 9 by the enlargement / reduction ratio obtained in step (5-3) or step (6-7) is used. The size of the character size.

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 minimum size set in advance in step (5-10) shown in FIG. Keep it.

Then, the characters are arranged one by one with the character size determined in step (6-4), the characters are folded back beyond the horizontal area, and the continuation is arranged from the beginning of the next line. Go. 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 with the character type and character size specified by the element When all the characters have been arranged, the height of the area is calculated from the number of lines and the font size in step (6-5).

At this time, if the size of the line is specified by the CSS property, it follows the size. If not specified, a certain value for the character height is set as a standard. Set the value of.

On the other hand, this is the case where it is determined in step (6-2) that the element is an image element.
Proceeding to 6), processing for determining the area of the image element and determining the arrangement position is performed. In the present embodiment, the method of determining the size of the image area is as follows. The aspect ratio of the size of the image area specified in the XHTML document is determined by calculating the aspect ratio of the cell obtained in step (6-1). Determine the height by applying to the horizontal area.

Then, in step (6-8),
It is checked whether or not there is a cell to be further processed. If it is determined that there is a cell, the process proceeds to step (6).
Returning to -2), the same processing is performed. If it is determined that no cell exists, the processing is terminated.

FIG. 11 is a diagram showing an example of a print image displayed on the display device of each of the client personal computers X and Y shown in FIG.

In the figure, an arrow indicates a region to be edited, for example, a heading region, with a cursor by a pointing device (not shown) or the like, and the region is displayed in a form different from other regions, and indicates a currently selected state. .

FIG. 12 is a flowchart showing an example of a third data processing procedure in the information processing apparatus according to the present invention, and corresponds to a layout editing processing procedure on a screen on which a print image is displayed. (7-1) to (7-
16) shows each step.

First, in step (7-1), as shown in FIG. 1, a table, text, or the like is displayed on the current SVG document layout image displayed on the screen of the display device of the client personal computer X or Y. If you want to edit the layout for each area of the image, specify the target editing area with a mouse or the like.

In step (7-2), it is determined whether the specified area is a table area, a text area, or an image area.

When it is determined that the designated area is a table area, the process proceeds to step (7-3). When it is determined that the designated area is an image area, step (7-) is performed.
Go to 5) and if it is determined that the area is a text area,
Proceed to step (7-6).

When the process proceeds to step (7-3), since the designated area is a table, 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 a mouse such as a pointing device may be used, or a method of directly inputting a value on the UI screen may be considered. Do not mention.

Then, in step (7-4), the contents of each cell are changed corresponding to the changed area.

More specifically, 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 on 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. In the case of an image, the same enlargement / reduction ratio is applied to the vertical and horizontal sizes of the image area.

On the other hand, when the process proceeds to step (7-5), since the designated area is an image, the image area is enlarged or reduced to change the original image area. Change the vertical and horizontal area of the image according to the ratio of the image area.

On the other hand, if the designated area is a text in step (7-2), a change in the text area is performed in steps (7-6) to (7-14) as described later.

First, in step (7-6), it is checked whether or not the text area is related to an area change. When it is determined that the change is related to the area, the process proceeds to step (7-7), and when it is determined that the change is related to the font size and the typeface other than the area, the process proceeds to step (7-8).

In step (7-7), since the text area is changed, the ratio of the horizontal size to the original text area size and the changed text area size is calculated as follows. Apply to 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.

On the other hand, if it is determined in step (7-6) that the designation of the change is not the designation of the change of the area, that is, if it is the designation of the font size, typeface, decoration, etc. directly, From (7-8) to step (7-1)
In step (7-8), the process proceeds to step (7-8) to determine the change specification. If it is determined that the change specification is a font size specification, the process proceeds to step (7-9), and the typeface is changed. If it is determined that the change has been designated, step (7)
When the process proceeds to -11) and it is determined that the designation is to change the character to bold or italic, the process proceeds to step (7).
Go to -13).

Then, in step (7-9),
Since the specification of the change is the specification of the font size, the size is changed and arranged.

More specifically, the horizontal area of the original text area is not changed, and the characters are arranged one by one in a newly designated font size. When the character exceeds the horizontal area, the character is folded back there.

Then, in step (7-10),
After all the character strings have been arranged, a vertical area is obtained, and its size becomes a new vertical area of the text area.

On the other hand, if it is determined in step (7-8) that the typeface is to be changed, then in step (7-11), the horizontal area in the original text area is not changed, but is newly specified. Characters are arranged one by one in the font of the typeface. When the character exceeds the horizontal area, the character is folded back there.

Then, in step (7-12),
After all the character strings have been arranged, a vertical area is obtained, and its size becomes a new vertical area of the text area.

On the other hand, if it is determined in step (7-8) that the designation of the change is a change of the font to a bold font, an illuminated font, or a character without modification, the process proceeds to step (7-8). In (7-13), the horizontal area of the original text area is not changed, and the characters are arranged one by one in the font of the newly specified typeface. When the character exceeds the horizontal area, the character is folded back there.

Then, in step (7-14),
After all the character strings have been arranged, a vertical area is obtained, and its size becomes a new vertical area of the text area.

Next, in step (7-15),
A new page layout is performed by reflecting the changed area on the entire area.

Then, in step (7-16), it is determined whether or not the user is satisfied with the current layout and instructs termination, and if it is determined that termination is instructed, the process is terminated. If the process is not completed and the condition is not satisfied, the process returns to step (7-1), and the same region or another region is designated, and a new region conversion is performed.

As a result, as shown in FIGS. 13 and 14, it is possible to change the layout to a layout intended by the user and perform print processing.

FIGS. 13 and 14 are diagrams showing examples of layout editing output in the information processing apparatus according to the present invention.
