@Bevinsky The PDF part was just an example of where it happened, the actual files are in png. I tried gimp, but it took close to 30 minutes to typeset one page (though I can probably do it in 5-10 minutes after I do it for a bit longer, but it's still way longer than what it takes on preview)...
Translation seems good, but there's a few typos and I don't even know what is with the random boxes every so often. You may also want to start using png files to reduce compression and use the original image file size from the raws. The typesetting can also be improved a lot. Keep up the good work!
If you want to ask why the second page's font is a little different, it's because I tried using gimp to typeset but it took half an hour just for one page so I gave up on that but I also didn't want to typeset a page I already typesetted.
@Bevinsky Using Preview to edit them. Currently using the version on OS X 10.14 and the compression problem didn't happen on my old macbook that I don't have anymore which had OS X 10.13, but they removed the option to go back to previous versions of OS X in 10.14 so I can't even go back to...
