Thanks - looks like these all have invalid extended headers. I guess QuickDraw just ignores the extended header if its version field has an incorrect value in it, so I made resource_dasm do the same (revision da55fe5) and now all of these render properly.

Feel free to reopen this issue if you find more PICTs that don't work - one of the goals of this project is maximum compatibility.

Thanks for the report - this is fixed in revision 7668295. The issue was that in PICT command 0C00 (extended header), we didn't change the canvas size if the extended header specified a different size than the main header. This seems to be a fairly rare case, but fixing it corrects about 120 PICTs in my testing dataset, which is a notable improvement.

Ah, I missed the second part - yeah, for the other PICTs that fail completely, please upload them here and I'll take a look.

Sure, here you go. Three of these PICTs actually fail conversion in picttoppm too. And yet all of them QuickLook correctly in the Finder and can be opened in Preview!
