- ; Filename : COLCODE.INC
- ; Description : ASM include file for defining special colour
- ; see/update also COLCODE.H for C
- ; for transparent code repeated for 1 to UNIQUE_REPEAT_CODE_NUM times,
- ; write FEW_TRANSPARENT_CODE(repeated_times)

- ; write two bytes, MANY_TRANSPARENT_CODE and repeated_times
- TRANSPARENT_CODE = 255
- UNIQUE_REPEAT_CODE_NUM = 7 ; total no. of bytes used by transparent pixels and compressed transparent pixels is 7+1 (the last 1 is the first byte of the 2 bytes compression code)
