Description

DETAILED DESCRIPTION OF THE INVENTION (Field to which the invention pertains) The present invention relates to kerning processing in a document creation device, particularly for Roman languages, equipped with a word processor function (document processing function).

[Description of prior art]

As shown in FIG. 1(a), all the characters in conventional devices of this type have rectangular character faces of the same size. However, because the widths of letters such as W and I are different, it is not possible to line up the letters neatly on a letter surface of the same size, so the width of each letter is changed and output as shown in Figure 1 (b). It was way.

However, if V or W comes after A, or vice versa, if they are lined up as is, it will give the impression that the spacing between the letters is a little wider than the other letters. Therefore A
The document will look better if the spacing between and V is made a little narrower than the normal character width, so as shown in Figure 2, the location of the next character is moved a little 8 times from the normal location. This kind of process is called kerning processing. In the case of English, when writing beautiful documents, it is also necessary to perform kerning processing on characters to a greater or lesser extent.

In order to perform kerning processing, it is necessary to determine the amount of movement of the subsequent character from its normal position based on the relationship between the currently handled character and the previously handled character, which complicates the process and also It is also necessary to register the amount of kerning for all cases of kerning in the dictionary in which kerning is registered, which has the disadvantage that the dictionary also becomes complicated. For this reason, kerning processing has only been performed using high-end document creation devices.

[Object of the present invention]

An object of the present invention is to eliminate the drawbacks in the kerning process as in the above example and to easily perform the kerning process by determining a unique character face and a plurality of reference points for each character.

〔Example〕

FIGS. 3 to 6 are diagrams showing an embodiment of the present invention, which will be explained below in accordance with the figures.

FIG. 3 is a diagram showing an embodiment of the present invention, where 1 is a keyboard (KB) for inputting characters, and 2 is a keyboard for externally storing characters input from the keyboard 1 or for re-entering characters. A floppy disk (FD), 3 is a RAM for temporarily storing input characters and data for calculating character placement.
andomAccess Memory), 4 is a CPU for processing character placement and controlling peripheral devices,
5 is a ROM (Read Only) in which the dot patterns of characters and the positions of reference points are registered.
6 is a CRT for displaying the processed results, and 7 is a printer for printing.

Figure 4 shows examples of character dot patterns, character faces, and reference points registered in the ROM5. This is an example in which reference points representing the shape and size of the character surface are placed at a total of six locations: the upper left corner, the center left edge, the lower left corner, the upper right corner, the center right edge, and the lower right corner. From now on, the embodiments will be described according to the above example.

FIG. 5 is a flowchart showing the operating procedure of this embodiment, with Sl to Sit representing each operating step. In the figure, the symbols A to F shown at each step are the reference points shown in Figure 4, and σ, E', and F' are the positions of reference points D, E, and F when the characters are incorporated into the document. It represents the horizontal coordinate, that is, the horizontal position of the rightmost edge of the document currently being created. This process is performed after a document is input into the RAM 3 from the keyboard 1 or the floppy disk 2.

First, initialize E' and F' (si)
, that is, the horizontal coordinate of the starting position of writing the document is D′,
Put it in g%r. Then input one character from RAM3.
2) Check whether it is an end symbol (EOF in the figure) (S
3). If it is an end symbol, the process returns to the main routine, and if it is not an end symbol in S3, the reference point A of the input character is adjusted to the position of D' (S4). Then, examine the relationship between the position of reference point B and g (S5
). If B is on the left side of Y, the input character is moved to the right and the reference point B is aligned with the position of B (S6). In S5, B matches Bi, or B
If it is on the right side of the corner, the position of the character will not be changed. The above-mentioned positional relationship can be found, for example, as follows.

With the right direction being positive, B is dxt in the horizontal direction from the position of A.
, E' are located at dX2 in the horizontal direction from the position of σ. When A and σ are matched, dxl<dx2-B is to the left of Bi.

dX1=dX2→B is in agreement.

dxl>dx2-B is to the right of g.

Therefore, you can use this. Similarly, the positional relationship between C and C is checked (S7). If C is on the left side, the input character is moved further to the right and the reference point C is aligned with the position of r (S8). C in S7
If C and C match, or C is to the right of r, the position of the character is not changed. Then, store the finally determined character position in RAM3 (S9), incorporate the character into the document (SIO), and set the horizontal coordinates of the reference points D, E, and F of the incorporated character to new D', E'
, F' and return to S2 to repeat the above-described process.

FIG. 6 shows an example of a comparison between the result (a) of document processing according to the procedure of FIG. 5 of the present invention and the result (b) of document processing using conventional rectangular characters. be. However, the width of the rectangular character surface in b) is such that the character surface of each character defined in FIG. 4 has the maximum width. Input characters are AVXOE, and kerning processing is performed between AV and XO, and (
It is slightly narrower than b).

The width between vx and between OE is the same as in (b).

In the above embodiment, six reference points are provided, but the same processing can be performed by defining three reference points A, B, and C and the width at each reference point.

[Explanation of effects]

As described above, according to the present invention, since each character has a unique character face, it is possible to easily perform kerning processing, and the structure of a character registration dictionary for performing kerning processing is also simplified. is now possible.
