- How does one read pixels in 16 color planar modes?
- There seems to be only 2 read modes.
- 1 comparing 8 pixels to a color compare register.
- 2 reading the byte plane by plane.
- It seems to me that the 1st method requires up to 15 compares
- and the 2nd needs 4 reads.
- Surely there must be a better method (NOT int 10h service 13)
-
- thanks.
