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:
