Abstract

PROBLEM TO BE SOLVED: To provide a technology capable of performing the line typesetting process of characters having different fonts and different size properly without depending on a base line which is preliminarily set to the fonts. SOLUTION: In an electronic line typesetting, the embox (virtual body) of characters is decided based on the size of the characters which are to be subjected to a line typesetting process and a new matched point is decided by comparing the M-box with a preliminarily decided reference character belonging to the same font and, then, the pertinent characters to be processed are made to be matched on the matched line in the line by using this matched point.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates generally to desktop publishing (DTP) technology, and more particularly to line publishing technology in DTP.

[0002]

2. Description of the Related Art A reference line called a baseline is set for a digital font used in DTP, and even a CJK (ideographic character such as Chinese, Japanese, or Korean) font including a Japanese font is usually used. A baseline has been set. For line formatting, when Japanese and Western are mixed in one line, use the baseline of each font to adjust the relative positional relationship between Japanese and Western. .

FIG. 13 shows a state in which text in which both Japanese and European texts are mixed is line-composed. The first five characters "depression" to "X" are Japanese fonts and the next five characters " “Å” to “x” are European fonts. In a Japanese font, one character is a substantially square embox (same as a so-called “virtual body”) 21
The embox 21 is located at the top 21
a, an intermediate portion 21b, and a bottom portion 21c. The vertical distance between the top 21a and the bottom 21c of the embox 21 defines the height of the embox. Further, a baseline 21d is set for the emboxes for these Japanese characters. On the other hand, in the European font, the ascender line 31a, the cap line 31b, and the base line 31
d, descender lines 31c and the like are set. The vertical distance between the cap line 31b and the base line 31d defines the cap height, that is, the height of a half-width capital letter in Western text. In FIG. 13, the line composition is performed by matching the baseline 21d for the Japanese font with the baseline 31d for the European font.

By the way, CJK including Japanese fonts
Although a baseline is set for fonts,
In Japanese fonts, the position of the baseline does not have a direct meaning, especially in relation to the embox, and is thus set independently and arbitrarily by the font designer. For this reason, in the CJK font, the position of the baseline is not the same in all the CJK fonts, and differs in principle from one font to another. Therefore, for a person who thinks that the line composition state is appropriate for a text in which Japanese and European characters are mixed as shown in FIG. 13, if the character is replaced with a Japanese character of another font, a line different from FIG. It is fully expected that it will be in typesetting. In such a case, it is necessary to shift the baseline of the Japanese or European character side up and down with respect to the other baseline. Alternatively, it is necessary to input a numerical value via a keyboard and move it.

Further, even if the fonts are the same, if the size of the character (for example, the point size) is different, the absolute position becomes larger as the size increases, even if the relative position of the baseline is the same. Shift. Therefore, FIG.
As shown in FIG. 4, when characters having the same font but different point dimensions are aligned on the alignment line 23 with their respective baselines, the lower part of the large-sized character is lower than the small-sized character. Will protrude. That is, in FIG. 14, in the embox 21 of each character having a different size, the portion near the bottom of the large embox protrudes downward by Δh as compared with the small embox. Such a line composition state is not acceptable in Japanese composition. Therefore, even in this case, using a mouse or keyboard,
It is necessary to manually modify the line composition.

[0006]

FIG. 3 schematically shows a series of text data composed of a plurality of characters C1 to C5. These characters C1 to C5 can be input, for example, by a user operating a keyboard, or A state where the data is stored in a storage medium in the DTP processing control device 2 from another storage medium, such as an FD, via the input unit 5 is shown.
Therefore, these characters C1 to C5 merely show a difference in size according to their order and their emboxes, and the characters C1 to C5 are subjected to the typesetting processing based on the line typesetting control of the present invention. To be arranged in one row in a predetermined matching state. It is assumed that each character Ci has at least font information and size (for example, point size) information as its attributes.

FIG. 4 is a flowchart showing a flow of a series of processing of a line composition control procedure for matching characters in a line based on an embox according to one aspect of the present invention. That is, when the line composition process for a plurality of characters is started in the DTP system 1 or 10 as shown in FIG. 1 or 2, first, the character C to be matched with a matching line (for example, a reference straight line) in the line.
An embox for each of i (i = 1 to 5 in the example shown in FIG. 3) is determined (step S1). Note that, in the present invention, the embox corresponds to a so-called “virtual body”, and refers to the outermost contour of a character, and the height and width are defined by the size (for example, point size) of the character. Is a substantially square outer frame.
The fact that the embox of each character Ci is determined in step S1 means that it is possible to match the character Ci with the matching line in the line based on the embox, and accordingly, the embox Is implied that a new matching point of the embox is determined.

FIG. 5 is a flowchart showing one procedure for determining a new matching point of the embox as a preferred embodiment in step S1 in the flowchart of FIG. Then, FIG.
FIG. 6E is a schematic view exemplarily showing a state in which the matching point of the embox is determined according to the procedure shown in the flowchart of FIG. 5. That is, as shown in the flowchart of FIG. 5, first, it is determined whether or not the font of the character C1 (in this example, the character “skill” 20 of 12 points) has the embox matching point information (step). S11). That is, if the font of the character C1 has the embox matching point information, if the matching point of the embox of the character C1 can be determined based on the matching point information, step S18 is performed.
Branch to On the other hand, if the M-box matching point information does not exist, or if it does exist, it is impossible to determine the necessary matching point from it, the process proceeds to step S12, and the process proceeds to step S12. It is determined whether or not it is possible to obtain the bounding box information of a predetermined reference character (in this example, “depression” and “eternal”). Note that the bounding box is a box composed of a pair of horizontal lines and a pair of vertical lines surrounding the glyph of the character C1, and is usually slightly smaller in size than the embox of the character C1. To be housed. If the bounding box information is obtained, the relative position of the embox is calculated using the bounding box information, and the process proceeds to step S14 to determine the position of the character C1. If there is no bounding box information, the process proceeds to step S13 to determine the bounding box by another method.

In step S13, the character C
A bounding box 22a of a predetermined reference character (in this example, a single-byte capital letter "H" having a size of 12 points) having the same font (12 points in this example) as the font 1 is determined. The single-byte capital letter "H" has a size of 12 points, but its cap height is about 10 points. In this embodiment, the single-byte capital letter "H" is used as the reference character. However, the reference character in this case is not limited to the single-byte capital letter "H", and is basically a character C1.
It is possible to use a character belonging to the same font and having a cap height. For example, it is also possible to use a half-size capital letter "X" as a reference character. A character having a cap height has its lower end corresponding to the baseline of the font.

Next, in step S14, an embox 21 having the width and height of the point size (12 points in this example) of the character C1 is formed. Step S14 can be performed before step S12.

Next, the centering of the bounding box 22a of the reference character (in this example, one-byte capital letter "H") is performed within the embox 21 (step S1).
5). On the other hand, it is also possible to center the single-byte capital letter “H” as the reference character in the em box 21 together with the bounding box 22a. Next, the centering bounding box 22
a or the bottom (lower end) of the single-byte capital letter "H" is determined as a new origin of the M-box 21 (step S1).
6) Further, at least one of the top, middle, bottom, and origin of the embox 21 is defined as a reference point (matching point) of the embox 21.
Is determined (step S17). The character C1 can be positioned at a predetermined position in the line by aligning the reference point (alignment point) determined in this way with the alignment line in the line. FIG. 6E shows the origin of the embox 21 determined by the above-described procedure (that is, the bottom (lower end) of the bounding box 22a).
Is determined as a matching point, and the matching point is matched with the matching line 23 of the row. Therefore, Mbox 2
A horizontal line passing through the first origin may be regarded as the corrected baseline of the character 20.

According to this embodiment of the present invention, the embox 2 which sets the point size of the character 20 to the vertical and horizontal dimensions.
1 and a new alignment point is determined as the modified baseline (origin) for the embox 21 and using this alignment point the embox 21, and thus the character 20, is aligned with the alignment line 23 of the line. It is possible to align and position. Furthermore, it is also possible to determine another arbitrary point on the embox 21 as another matching point with the new matching point thus determined as a base point. That is, according to this embodiment of the present invention, it is possible to determine a uniformly corrected baseline based on the principle of this embodiment, regardless of which font the character 20 belongs to. Yes, therefore, even if a plurality of characters belonging to different fonts or a plurality of characters belonging to the same font but having different dimensions are to be line-composed, the same principle is applied to all the characters in the line. The corrected baseline, which is the reference point (coincidence point) determined by the above, is newly determined and the line composition is performed based on the reference point (coincidence point). It is possible.

The processing for the character C1 has been completed as described above, and the process loops back in the procedure of FIG. 5 to return to step S11, and the same processing is repeated for the next character C2. However, although not shown in the flowchart of FIG. 5, when the character C2 belongs to the same font as the character C1 and has the same size (point size), the matching point determined for the character C1 is adopted. However, it is possible to avoid repeating the same process as C1 for C2. This makes it possible to improve the processing speed. On the other hand, if the character C2 is different from the character C1 in any one of the font type and the font size, the procedure of FIG. 5 is repeated again for the character C2. For example, among the five characters shown in FIG. 3, characters C1, C2, C3,
If character C4 belongs to the same font and has the same dimensions, and character C4 belongs to the same font as the other characters but has different dimensions, the matching point determined by the procedure of FIG.
2, C3 and C5 are applied as they are. Therefore,
The procedure in FIG. 5 is not repeatedly performed for each of the characters C2, C3, and C5, and the processing efficiency is improved. On the other hand, since the size of the character C4 is different from that of the other characters, the procedure of FIG.
Is uniquely determined for the matching point.

As described above, the five characters C in FIG.
An embox and its matching point are determined for each of 1 to C5 (step S1). Next, returning to FIG. 4, the character having the largest dimension (in this case, the character C4) among the plurality of characters C1 to C5 to be arranged in one line is Cim.
ax is determined (step S2). Next, the height of the character Cimax having the maximum size is set to the height T of the line.
(Step S3). Then, reference points (matching points) determined for each of the characters C1 to C5
With the reference line (alignment line) of the line
The character C5 is positioned, and then the characters C1 to C5 thus positioned are positioned at the center with respect to the line height T (step S4). Thereby, the character C
The line composition processing for 1 to C5 ends.

FIGS. 7A and 7B show a state in which five Japanese characters 24a to 24e are subjected to line composition processing according to the prior art and the present invention, and are aligned on the alignment line 23. . Although the characters 24a to 24d have the same dimensions, the characters 24a, 24d, 24e
And the characters 24b and 24c belong to different fonts, respectively, and the characters 24a, 24d and 24e belong to the same font. Further, it is assumed that the character 24a and the character 24d have the same size, but the character 24e has a larger size. FIG. 7A shows the character 24
This is a case where the baseline set in advance for each of the characters a to 24e (that is, the baseline defined by the designer of each of these characters) is aligned on the alignment line 23 and positioned. On the other hand, FIG. 7B shows a case where a new embox is determined for each of the characters 24a to 24e based on the embodiment described above with reference to FIGS. The figure shows a case in which the positioning is performed while being aligned above.

FIGS. 8A to 8C show a new alignment of the bottom, top, or middle of the em box 21 determined according to the row composition control procedure of the present invention described with reference to FIGS. The state of matching on the matching line 23 as a point is shown. Note that these are all cases where typesetting is performed in horizontal composition, but it is needless to say that the present invention is applicable to the case where typesetting is performed in vertical composition.

Next, a row composition control procedure according to another embodiment of the present invention will be described with reference to FIGS.
In this case, it is assumed that also in the line composition control procedure, the line composition processing is performed on a series of characters including a plurality of characters C1 to C5 shown in FIG. First, as shown in the flowchart of FIG.
Is determined (step S2).
0). The M box 21 in this case has the same configuration as the M box 21 in the embodiment described above. Therefore, a substantially square frame having the vertical and horizontal dimensions of the character C1 (for example, point dimensions) is determined as the embox 21.

Next, an ICF box for the character C1 is determined (step S21). Where ICF
(Ideographic Character Face) is an ideographic character face (also called "average character face")
One embodiment of the routine for determining the F box is shown in FIG. Therefore, the procedure for determining the ICF box and its matching point will be described with reference to FIGS.

That is, first, the font of the character C1 is determined (step S30). Next, the bounding boxes of two predetermined different reference characters belonging to the font thus determined are determined. In this embodiment, as the two different reference characters, two characters "depression" and "eternal" are used as shown in FIGS. 11A and 11C. However, the reference character in this case is not necessarily limited to these two specific characters, and in another embodiment, another character can be used as the reference character. In that case, the reference character in this step is (1) the glyph is relatively square,
Other characters can be used as long as they satisfy the three conditions of (2) being a Chinese character and (3) being as large as possible. Note that, in the present embodiment, the “eternal” character is used as one reference character. Although the reference character deviates somewhat from a square shape, the reason why it is adopted as the reference character is that it is a typical kanji character that well reflects the balance of the font design. Therefore, in the present embodiment, it is possible to determine an optimal ICF box of a font by using two characters “depression” and “eternal” as reference characters.

Although two reference characters are used in this embodiment, the number of reference characters in this case should not be limited to two, but one, three or more. Any number of reference characters can be used. However, although the accuracy can be improved as the number of reference characters increases,
Since the processing time (particularly, the processing time for determining the bounding box) increases, the processing is delayed. In order to obtain sufficient accuracy without causing significant delay, it is preferable to use two reference characters as in this embodiment.

As a result of the processing in step S31, in this embodiment, as shown in FIG. 11A, the bounding box 30 of the first reference character "depression" is determined, and is further shown in FIG. 11C. As described above, the bounding box 30 of the second reference character “Ya” is determined.
Then, as shown in FIG. 11 (B), the difference a, a ', b, b', c, c ', up, down, left and right between the bounding box 30 and the embox 21 of each reference character.
d and d 'are determined (step S32). Next, these eight differences are added, and the result of the addition is divided by 8 to determine the average value of the differences (step S3).
3). Next, a new box is defined by being positioned inside the em box 21 by the distance of the average value of the differences thus obtained, and this box is defined as the ICF box 31 (see FIG. 12) (step S34). Next, ICF
One of the top, middle, and bottom of the box 31 is selected as a matching point (step S35). In this way, the ICF box 31 for the character C1 is determined, and the matching point is also determined.

Next, the same processing is performed for the next character C2. In this case, for example, if the character C2 and the character C1 belong to the same font and have the same dimensions, the character C1 It is needless to say that the values of various parameters that have already been determined in the processing can be used as they are, and it is not necessary to repeat the same processing. However, if the next character to be processed belongs to a different font, or if the font is the same but the size is different (for example, character C4), it is possible to carry out all of the procedures in FIG. is necessary. In this way, matching points are determined for each of the characters C1 to C5 based on the ICF box (step S21 in FIG. 9). Therefore, character C
By arranging the respective matching points 1 to C5 so as to be aligned with the matching lines in the line, the characters C1 to C5 can be accurately and visually positioned (step S22).

FIG. 12 shows an example in which the ICF box 31 is determined based on the above-described embodiment, and the ICF box 31 is aligned on the alignment line 23 with the bottom of the ICF box 31 as an alignment point. In this case, the emboxes of adjacent characters are out of alignment and are not aligned, but their ICF boxes are aligned on the alignment line 23 at the bottom. ICF
The box determines the relative position between a pair of adjacent glyphs based on the actual glyph of the character,
It is possible to perform line formatting with higher accuracy as compared to the line formatting procedure based on Mbox. Therefore, especially when the size of the character to be line-composed is large, I
It is desirable to use a line formatting procedure based on CF boxes. However, in the line composition procedure based on the ICF box, it is necessary to calculate the bounding box of the glyph, so that the processing time tends to be increased.

In the above embodiment, one of the three possible positions of the top, middle and bottom of the ICF box is selected as the matching point.
Of course, any other point on 1 can be selected as the matching point. Further, in the above-described embodiment, when determining the ICF box, one average value is calculated for the difference between the bounding box of the glyph of the reference character and the em box of the character under consideration. However, in another embodiment, a first average value of the upper and lower differences and a second average value of the left and right differences between the bounding box of the reference character and the embox of the character under consideration are determined, It is also possible to determine the ICF box inside the embox by separating the embox vertically and horizontally by the first and second average values, respectively. Further, it goes without saying that the present invention can be applied to not only Japanese fonts but also European fonts. That is, for example, it is also possible to determine an embox for a European font and use the embox to arrange along an alignment line.

Although the specific embodiments of the present invention have been described in detail above, the present invention should not be limited to these specific examples, but may be variously modified without departing from the technical scope of the present invention. Of course is possible.

According to the present invention, line composition can be performed accurately and visually beautiful even for a plurality of characters having different fonts or dimensions. Furthermore, according to the present invention, even if a character is misaligned when a line is formatted based on a baseline set by a font designer, the character is automatically and without requiring manual work. It is possible to eliminate such misalignment and efficiently implement a desired line composition.
