Really - I didn't know that! Or are you talking about just
24bit *.rle's? My (delphi\)winapi.hlp says "... and each 3-byte
sequence in the bitmap array represents the relative intensities of
red, green, and blue, respectively, for a pixel."
I've never tried this (a Delphi T24BitBitmap is close to the
top of my to-do list) so you may be right - if you were only talking
about RLE's we could both be right.
