SL CACHE VIEWER BLURRY HOW TO
And, as per this community's rules, I will not be providing any information on how to remove the DRM from these files. Please keep in mind, this method is only intended to be used on books you have legally borrowed from Internet Archive, and will return to them when your loan period concludes. Though with books that are primarily text-based, you can also download the PDF, convert it to JPGs (I do this with all of my IA downloads anyway, so I can batch-edit the color/contrast to make them clearer and easier to read - and also because IA's automatically-made PDFs are slow to render for me), and replace any illustrations in the book with the JPG files from your cache.Īnyway, I figured I'd share this here, on the off-chance that this method might help someone else out there.
SL CACHE VIEWER BLURRY PDF
Of course, many files on IA aren't effected by this, because either the original upload IS a high quality PDF, or because the book itself is mostly text - in which case, downloading the PDF is your best bet. But for small out-of-print children's books from decades past (like the Care Bears book I referenced above), this is a completely valid workaround to get the highest quality images available of otherwise UNavailable things. Admittedly, opening each individual page and saving it as a new file would be a bit too tedious for most of us to bother with for, say, a 100+ page artbook.
Incidentally, this can also work with video and audio files. Unfortunately, it doesn't let you directly save the files as what they're meant to be, but you can open them in an external program, and save them from there. However, you can download a nifty little tool by NirSoft called Chrome Cache Viewer that will let you view media in your cache as what it is, instead of the html/text files Chrome saves them as. Those JPGs are in your browser's cache once you view the book in IA's embedded viewer, but because of the way Chrome stores the cache, they're not directly viewable by you - and scouring the coding of the embedded viewer doesn't result in any unsecured file links to view them outside of the viewer. However, the ridiculous blurriness in the second image can't be so easily remedied. Admittedly, both images are dark, but this can easily be fixed in almost any image editing program. Here's an example from an out of print Care Bears book from the 1980s: Original JPG versus Same Page in downloadable PDF. The PDF file you download is, in fact, the "official" PDF of those images - but the compression it undergoes in its creation can wreak havoc on picture book illustrations and artbooks.
SL CACHE VIEWER BLURRY ARCHIVE
I've figured out that Internet Archive is displaying the hard data in their viewer - namely, the jpg images taken from the zip/cbz file that was directly uploaded by the person who scanned the book.
No one had any answers for me, but I kept at it off and on since then. So awhile ago, I posted a question on here about picture books I was borrowing from Internet Archive where the illustrations in the downloaded PDF were noticeably lower quality than the illustrations in the embedded IA viewer.
