Sind die Bilder nicht im ILBM Format? Das sollte alles Planar abgelegt sein. Siehe Wikipedia: https://en.m.wikipedia.org/wiki/ILBM
ZitatIn ILBM files the BODY chunk stores the actual image data as interleaved bitplanes (and optional mask) by row. The bitplanes appear first from 1 to n, followed by the mask plane. If the image is uncompressed then each line will be made up of
(width + 15) / 16
16-bit values (i.e. one bit per pixel, rounded up to the nearest multiple of 16-bits.) If it is compressed then each line is compressed individually and is always a multiple of 16-bits long when compressed.
Und da es 16 Bit Werte sind könnte es sein dass man noch byteswap machen muss.
