3. OPERATION AND TIMING
r. Color Editing
This block executes the following color editing:
• Gradation
• Color filter
• Base color
• Coloring
• Special effect
• Text composition
Except in “text composition,” bit map data is generated based on the mode data (pattern and color of
gradation or area) selected on the control panel and integrated with image A, which has been read by the
scanner.
Figure 3-341
In the case of “text composition,” image A, which has been read by the scanner, is converted into binary
data by the ED Board A1; then, bit map data is generated based on the area data. The bit map data is
temporarily stored in the bit map memory and integrated with image B, which has been read next.
