My answers are not necessarily official YACReader statements but mostly represent my own opinion in technical matters.

Arithmetic jpeg already works on YACReader on Archlinux. There's a reason it doesn't on Win and Mac:
libjpeg, which is bundled with QT, doesn't support arithmetic. On Linux, this has been replaced by libjpeg-turbo which does support arithmetic decoding and can be used as a drop-in replacement for libjpeg. It's also faster
Some more info: bugreports.qt-project.org/browse/QTBUG-40091
.DjVu is an alternative to .pdf, so it isn't even an image format.

Ok, it turns out that it works with this version
. Perhaps I tried it with corrupted files or something like that, but it definitely works. Try it in your system with the arithmetic JPG file of this site:

Mariner, have you tried opening a jpeg with arithmetic encoding in YACReader?
