There is a problem that the processing time is longer than that. On the other hand, the latter device overlaps the main body part and the background part in order to store in advance the font data including the body part and the background part, and the font data with the border part representing the body part and the background part and the background part. There is a problem that the amount of stored font data is doubled.

The present invention provides an apparatus and method for suppressing an increase in processing time and storage amount of font data and generating bitmap data of bordered characters, figures, and borderless characters, figures at high speed with a small storage capacity.

The color number of the notified background color is recorded (step 22).

The borderless coloring unit 131 obtains a color number corresponding to the pixel value of one pixel of the font data notified from the font data reading unit 111 by referring to the gradation color table 503 (step 23), The color number is recorded in the corresponding field of the bitmap data table 504 (step 24). This process is performed for all pixels of the font data (step 25).

Fig. 10 shows the result of executing steps 21 and 22 when the background color is 0 (white), the first body color is 255 (black), the second body color is 128 (gray), and the rim color is 64 (red). The contents of the obtained gradation color table 503 are shown. 0 (white), which is the color number of the background color, is recorded in the color number column of the border part.

FIG. 11 shows the contents of the bitmap data table 504 obtained as a result of performing steps 23 to 25 in accordance with the contents of the gradation color table 503 of FIG. 10 with respect to the font data of FIG. O (white), which is the color number of the background color, is recorded in the pixel of the border portion, and the border is not performed.

As described above, in the first embodiment, when the font data of the bordered character and figure is stored in advance, the font data of the body part, the border part, and the background part is read out from the storage means in the case of the border. Since bitmap data is generated, it is not necessary to perform arithmetic operations for calculating the borders of characters and figures in turn, and the increase in processing time can be suppressed. If no edging is done, the edging portion of the font data stored in the storage means is replaced with a background portion to generate bitmap data of characters and figures consisting of the main body portion and the background portion. There is no need to keep the memory, so that an increase in the storage capacity of the font data can be suppressed.

As a result, it is possible to provide an apparatus for generating bitmap data of borderless characters, figures, and borderless characters and figures with high speed and low memory capacity.

In the above embodiment, bitmap data without borders was generated by substituting the border portion with the background portion, but similarly, the bitmap data of the character with the center removed, consisting only of the fringe portion, was substituted by substituting the body portion with the background portion. Can be generated.

In addition, the generation instruction may be represented in another format. For example, you may want to associate a border need / unnecessary flag with another value, specify the color as an RCB value, and character code as a different code specification. When the color is specified in the generation instruction with RGB values, the recording of the colors in the generation instruction buffer 102, the gradation color table 503, and the bitmap data table 504 is performed with the RGB values.

In addition, a generation instruction for generating bitmap data of a plurality of characters in which the border needs / unnecessary, the background color, the first main body color, the second main body color, and the border color is common, includes one common designation and a plurality of character codes. You may comprise with. In this case, the bitmap data generating device repeats the bitmap data generating process a number of times for one common designated content.

The font data may be supplied from outside of the apparatus. Fig. 16 shows an example of the configuration of the bitmap data generating apparatus 150 in this case. The bitmap data generation device 150 has a font data acquisition unit 151 instead of the font data reading unit 111 and the font data storage unit 110 with respect to the bitmap data generation apparatus 100 of FIG. 3. The font data acquisition unit 151 acquires font data corresponding to the character code notified from the character code acquisition unit 105 from a font data storage unit provided in addition to the device, and makes a border with the coloring unit 130 having a border. Notified to the coloring unit 131 without.

The font data storage unit other than this apparatus may hold font data represented in the outline format. Techniques for generating font data represented in bitmap form by expanding font data represented in outline form are widely known, and font data storage units other than the present apparatus are converted to bitmap form from font data stored in outline form using the known technique. The indicated font data can be generated and supplied to the bitmap data generating device 150.                     

In addition, the rim coloring unit 130 and the rim coloring unit 131 correspond to the color number or RGB value corresponding to each pixel value one by one with respect to the font data notified from the font data reading unit 111. May be obtained from the gradation color table 503, and the acquired color number or RGB value may be output to the display device.
