Amiga IFF to Bitplane converter: iff2bpl 1.0

FF2bpl converts IFF-ILBM images into various formats that are important for programmers or pixel artists:

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: github.com/panzi/qilbm/blob/42
rendering: github.com/panzi/qilbm/blob/42
sample file: sembiance.com/fileFormatSample
Other impl. I've looked at and can't finde the difference to:
aminet.net/package/dev/misc/PC (includes 2 images that *do* work)
fossies.org/linux/netpbm/conve line 1596 and onward, which is used by #ImageMagick. #RetroComputing

The way https://sembiance.com/fileFormatSamples/image/iffILBM/pchgcmp.iff should look like.My broken rendering of it.

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

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.
