I need to grab the colour data from a bitmap, manipulate it then write it back to the bitmap. This needs to compile in D1.0 (without Win32.API) but needs to run reliably under W3.1 and W95. I really need to treat the data I get from the bitmap as 24BBP information, even if the bitmap was actually palettised. Pixels property and WinAPI GetPixels are WAY TOO SLOW. Speed is of the essence!
