- Hello. I'm using Turbo-C 3.0 soon tobe using 3.1. I've been playing with
- graphics and want to now the format of a turbo-c bitmap produced by getimage()
- function. I know that the must specify the mask map for colors and also
- the bit configuration. But DO they have to specified the color for each bit ?
- If so, the an image of 8 x 8 pixels would require:
- 8 * 8 bits * 4 bits = 256bits = 32bytes
- But in order to address a particular bit it appear to that they would
- have to do so shifting and also set each bit a time, this would entail
- 256 calls to outport command to 256 access to register and or memory data.
- THis doesn't sound very efficient to me. Is, there a better way or is that
- just what the people at Borland do? I'm very curious to know how they, and
- you, do this.

- Thankyou:
