Hi James,

I get the following message when i try to set a pixel in the
bitmap.......whats wrong and how can i fix it.......

"Additional information: SetPixel is not supported for images with
indexed pixel formats."

this is the code.........


bitmap.SetPixel(biheight,biwidth,Color.Black);
The get pixel works perfect but not this........

Try using colors from bitmap palette e.g. by:
Color[] paletteColors=bitmap.Palette.Entries;

If this won't work then only solution i see is
to convert your bitmap to 24bpp pixel format.

Remeber that GetPixel & SetPixel methods are very
unefficient!

Cheers
