You'll probably have to set the palette up before you try drawing |
|
in the new colours. |
|
Use the bios interrupt calls to set the r g & b values (in the range |
|
from 0-63 for most cards) for a particular palette colour (in the |
|
range from 0-255 for 256 colour modes). |
|
Then you should be able to draw pixels in those palette values and |
|
the result should be ok. |
|
You might have to do a bit of colourmap compressing if you have |
|
more than 256 unique rgb triplets, for a 256 colour mode. |
