Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation device such as a Japanese word processor, and particularly to a method for outputting character decoration.

[Summary of the Invention] A document creation device according to the present invention extracts the outline of a character,
This outline part is not modified, and only the part outside the outline part is modified, so that the characters do not become difficult to read.

[Prior Art] Conventionally, document creation devices such as Japanese word processors have been configured to be able to display or print out inputted characters by applying character modification such as shading.

The output of characters with such character modification, such as print output, is usually simply a diagonal line above the character.

This is done by overwriting the stitches. For example, when adding a diagonal line as shown in Fig. 8(b) to the character ``A'' as shown in Fig. 8(a), the same dot pattern is added by taking the logical sum of the respective dot patterns. As shown in Figure (C), characters modified with diagonal lines are generated and output.

[Problems to be Solved by the Invention] However, as described above, in the 8-power method of character modification that takes the logical sum of dot patterns,
As can be seen from the modified characters obtained as a result, there is a problem in that the shape of the characters is distorted by diagonal lines, making the characters difficult to read.

The reason for this is that by simply calculating the logical sum of two patterns to be synthesized, the outline of the character to be synthesized and the synthesized pattern such as diagonal lines are confused.

In other words, if the outline of the character to be composited and the composite pattern can be separated, that is, if the composite pattern is not composited with the outline of the character to be composited, then the resulting composite character will not be difficult to read. That is clear.

An object of the present invention is to prevent a synthetic pattern from being synthesized on the outline of a character to be synthesized.

[Means to solve the problem] The means of the present invention are as follows.

A character dot image data storage means 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) stores character dot image data of characters to be synthesized.

The combination pattern storage means 2 stores a combination pattern to be combined with a character to be combined.

The outline extraction means 3 extracts the outline of the character to be synthesized from the character dot image data stored in the character dot image data storage means 1.

When compositing a character to be composited with a composite pattern stored in the composite pattern storage means 2, the composition control means 4 selects among the character dot patterns of the character to be composited stored in the character dot image data storage means 1. The synthesis pattern stored in the synthesis pattern storage means 2 is synthesized only with respect to the range of the character dot image data excluding the outline portion of the character to be synthesized extracted by the contour extraction means 3.

[Action Co. The operation of the means of the invention is as follows.

When synthesizing the character to be synthesized and the synthesis pattern stored in the synthesis pattern storage means 2, the outline extraction means 3 extracts the outline of the character to be synthesized from the character dot image data stored in the character dot image data storage means 1. extract,
The composition control means 4 extracts the character dot image data of the character dot pattern of the character to be composited stored in the character dot image data storage means 1 excluding the outline portion of the character to be composited extracted by the outline extraction means 3. The synthetic patterns stored in the synthetic pattern storage means 2 are synthesized only for the range of .

Therefore, it is possible to prevent the composite pattern from being composited on the outline of the character to be composited, so that the resulting composite character does not become difficult to read.

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 2 to 6.

FIG. 2 is a diagram showing its configuration, and reference numeral 11 is a CPU that controls the entire system. 12 is an input section for inputting characters, and 13 is an external storage section for storing document files. A memory section 14 includes a document data area 14a for storing created documents, a character dot data area 14b for storing character dot data, and a buffer area 14c as a work area used for display, printing, etc.

Actually, the document data area 14a and the buffer area 14
c consists of a RAM, and the character dot data section 14b is composed of a RAM.
Consists of OM. Of course, this character dot data section 14b may be constructed from a RAM. Reference numeral 15 is a printing section for printing documents, and 16 is a display section for displaying characters.

Note that the character dot data section 14b stores dot images of characters, and based on this data, the characters are displayed and displayed.
Printing is done. Dot image data has one bit of data for each pixel, and if the data is ``1'', it is filled, and if it is ``0'', it is not filled. A character is composed of data for all pixels of one character. That is, if one character or 48X48)' cut, 48X48-2
It consists of 304 bits. Hereinafter, in this embodiment, one character is treated as 48×48 dots, but it goes without saying that the present invention is equally applicable to characters composed of other numbers of dots.

Further, the buffer area 14C is configured with six buffers A to F, and each buffer is configured as shown in FIG.
It has a capacity of 48x48 dots (-288 bytes), which is one character. Note that the storage format of each buffer is 0°1.2... ...and...

In the document creation device having such a configuration, characters input from the input section 12 are stored in the document data area 14a, and corresponding data is read out from the character dot image data section 14b and displayed on the display section 16. At this time, characters that have been modified (shading, etc.) are displayed in the state in which they have been processed. Similarly, when printing, the character dot data section 14
Data is read out from b and printed by the printing section 15.

Here, the modification to the output characters during display or printing is performed as shown in the flowchart of FIG.

That is, a modified character to be output, for example character data for "A", is read out from the character dot data section 14b (step S1), or data is read out from the buffer area 14c as shown in FIG. 5(a). A (step S2
). Further, modification data to be synthesized, for example diagonal line data, is read out from the character dot data section 14b, as shown in FIG. 5(b).
As shown, the data is stored in buffer B in the buffer area 14c (step S3). And the buffer area 14
The X register and the X register configured in c are each initialized to "0" (step S4).

Next, move up, down, left and right with respect to the dot at the coordinates of buffer A indicated by the X register and the value of the X register.

4. Calculate the logical sum in the diagonal direction and store the result in the buffer area 14c.
(step S5). That is, in FIG. 6, the position of D45 is D45''D41AD42Δ
It is calculated as D43AD44ΔD46ΔD47AD48AD49. Then, the value of the X register is increased by "+1" (step S6), and the resulting value of the X register is Max.
It is determined whether or not the value has reached X (48 in this embodiment) (step S7), and if it has not yet reached MaxX,
Return to step S5 above.

By repeating steps S5 to S7,
When the processing for the line is completed, next, set the value of the X register to "0", add the value of the X register to r+IJ (step S8), and set the value of the resulting X register to Max.
It is determined whether Y (48 in this embodiment) has been reached (step S9). If MaxY has not yet been reached, the process returns to step S5 and processes the next line. When the processing is completed for all dots in buffer A, the outline of the modified character "a" stored in buffer A is stored in buffer C, as shown in FIG. 5(C). Stored.

Next, two registers configured in the buffer area 14C are initialized to "0" (step 510). That is, the processing up to this point has been performed in bits (dots) using the x and X registers, but in order to increase speed, from now on, the values in these two registers are used to perform the processing in bytes.

That is, the inversion (NOT) of the data in the buffer C of the byte number indicated by the value of these two registers is obtained, and the result is stored in the byte position indicated by the value of the two registers of the buffer D in the buffer area 14C (step 511). Then, the value of register 2 is set to ``+IJ'' (step 512).
), the resulting value of the two registers is MaxXXMaxY
/8 (in this embodiment, 48×48/8 to 288 (bytes)), that is, it is determined whether all bytes have been processed (step 813). If all bytes have not been processed yet, the process returns to step Sll to process the next byte of data. In this way, when all the bytes of buffer C are processed, the buffer D stores the part other than the outline stored in buffer C, as shown in FIG. 5(d). become.

Next, after initializing the two registers to "0" (step 514), the data in buffer B (modified data with diagonal lines) and the data in buffer D (modified character (dots in the area other than the outline), and the result is stored in the buffer area 14c.
(step 515). Then, the value of the 2nd register is +IJ (step 516), and it is determined whether the resulting value of the 2nd register is MaxXxMaxY/8, that is, whether the processing for all bytes has been completed (step 516). 517). If all bytes have not yet been processed, the process returns to step 515 to process the next byte of data. In this way, when processing is completed for all bytes in buffers B and D, the outline of the modified character is stored in buffer E from the modification data stored in buffer B, as shown in FIG. 5(e). Partial or deleted data will be stored.

Next, after initializing the two registers to "0" again (step 518), the data of buffer A (character data of the modified character) and the data of buffer E (character data of the modified character) of the byte numbers indicated by the values of these two registers are set. The data is logically summed (data in which the outline part of the modified character is erased) and the result is stored in the byte position indicated by the values of the above two registers of the buffer F in the buffer area 14c (step 51).
9). Then, the value of the 2nd register is r+IJ (step 520), and the resulting value of the 2nd register is MaXXX
It is determined whether the value has reached MaxY/8, that is, whether the processing for all bytes has been completed (step 521).

If all bytes have not yet been processed, the process returns to step S19 to process the next byte of data. In this way, when processing is completed for all bytes of buffers A and H, as shown in FIG. The combined data will be stored.

As shown in step 2, it becomes possible to display or print out the outline of a character without modifying it.

Therefore, as shown in FIG. 7(a), in the conventional modification method, the composite pattern destroys the outline of the character, making the character difficult to read, whereas according to this embodiment, As shown in FIG. 5B, processing such as shading can be performed without destroying the contours of the characters, and the resulting composite characters will not become difficult to read.

In addition, in the above-mentioned embodiment, a hatching pattern for modifying character data was explained as a composite pattern, but the present invention is not limited to this, and for example, image data read from an image reader, etc. It may also be used as a composite pattern.

[Effects of the Invention] According to the present invention, since it is possible to prevent a composite pattern from being composited on the outline of a character to be composited, processing such as shading can be performed without destroying the outline of the character, and the result is The resulting composite characters will no longer be difficult to read.
