Deluxe Paint can't open that file as well. (I guess software from the early 90's also isn't supposed to open 3840x5760 24 bit images :-) ) PhotoShops IFF implementation is - I assume - mostly targeted towards Maya. it certainly is not compatible with anything Deluxe Paint related. (Photoshop can't read Deluxe Paint IFF files and vica versa)
I'll take a quick look what causing it, but as IFF is by design a container format where every program can define it own chunks, it's probably Photoshop specific, and probable a bit out of scope.
But still ... could be easy to implement.
Oh Interesting! I didn't know Maya supported IFF.
Btw I was unable to find grayscale IFF files (these don't have a CMAP chunk and are usually 8 bpp or less from what I could read). Any idea where I could find or how to generate one?
Couldn't Deluxe Paint V open IFF-24 pictures? I thought so. I'll dig up my original CD to find out.
Yes Deluxe Paint V can open IFF-24 bit pictures (and so can dpaint.js) But this is not a standard one.
Interestingly, some Amiga 24-bit image editors open it with the exact same garbled pixels as dpaint.js, so at least there's some consistency. :-)
And double interestingly: if the latest IFF datatypes are installed, multiview on Amiga CAN open it ... (and surprisingly fast)
OK, I'm intrigued. Time is limited this week, but I'll figure it out next week.
Hmm.. that's interesting.

That may be a hint: some 24bit ILBM files may be encoded using a different ordering:

ffmpeg also outputs garbage. I wrote an ILBM decoder for SerenityOS: I'll see what happens there.

I found a sample iff file that from what I read can be opened with Photoshop, but DPaint-js produces random pixels instead.
I don't have PhotoShop so I could not see the expected output.
