Hi,

EDIT(2), hexdumping `Grapes.Pict'

00000000  03 f0 - signature=$0f03
00000002  68 01 d6 00 01 00 - width=$0168, height=$00d6, depth=$0001
(B&W)
00000008  e0 3e 92 82 80 17 d4 00 d4 00 d4 00 d4 00 d4 00 - colour
table?

R,G,B = {byte}{byte}
colour = {R|G|B}
table = colour[0..255]

Then I am lost, which offset bitmap data starts? How to determine if it
is `RLE' compressed? 

Why we record the same width, twice?
  B.width := width;
  B.wth := width;

Tomas
