The open source tool Iff2Bpl converts ILBM image files into raw (interleaved) bitplanes, which can then be integrated into games or applications by developers. The author only provides the source code, interested parties must build the executable version themselves.

Just for fun I'm writing an #ILBM impl. for #Qt (QImageIOPlugin). I'm having trouble with the PCHG chunk. Any #Amiga dev/hobbyist here who might have a clue what's wrong? My code:
parsing: https://github.com/panzi/qilbm/blob/4222c4bdf5b81ab67fc68b3647ca231d1685d53a/src/ILBM.cpp#L865-L1097
rendering: https://github.com/panzi/qilbm/blob/4222c4bdf5b81ab67fc68b3647ca231d1685d53a/src/ILBM.cpp#L1297-L1346
sample file: https://sembiance.com/fileFormatSamples/image/iffILBM/pchgcmp.iff
Other impl. I've looked at and can't finde the difference to:
https://aminet.net/package/dev/misc/PCHGLib14 (includes 2 images that *do* work)
https://fossies.org/linux/netpbm/converter/ppm/ilbmtoppm.c line 1596 and onward, which is used by #ImageMagick. #RetroComputing

A long time ago (11 years ago), I wrote an JavaScript library to display IFF/ILBM files in a browser, surprisingly, it still works…

ILBM Animations

I have been hacking around on my small javascript library to load ILBM/IFF files, once I had fixed HAM decoding the next logical step was to add support for animations. This was for me a good oppor…

One ironic thing I realised while implementing a parser for the various original QuickTime codecs used for compressing images is that Amiga ILBM files with their bitplanes and Packbit compression would have fitted in perfectly. Now I wonder how hard it would be to implement an ILBM codec for 68k QuickTime. #retrocomputing #amiga #iff #ilbm #quicktime #quickdraw #classicmac #imageprocessing

While I was tinkering with my code to render Amiga HAM images, one challenge was finding good images. So I considered generating them myself, but this is not as easy as it sounds. Building an image…

Amiga ILBM files

This image (MEDUSABL.IFF) is one of the few Atari ST IFF files I could find on the web, it is quite typical of the graphics of the time: low resolution, 4 bit palette. The next big thing after the …
