I hope to have working PDF creation code ready by tomorrow. It already works 
in general, it's just super wasteful (3.2 MB JPEG turns into a 117 MB PDF 
since I haven't implemented image compression yet). And I didn't look into 
color profiles yet. Oh, and it is hardcoded to only support a single page with 
a single image until now. I will ping you once I have something worth looking 
at.
