Hi ,

I've created an 8bpp grayscale bitmap file using Bitmap.Save().
The dimensions are 504 x 480 pixels.
504 x 480 = 241920 , so I'd expect the file on the system to be at least 241920 bytes ( 8bpp )
but it's less than 1/3 that size (80,045 bytes).

Can anyone explain this to me please, it's twisting my melon man.
