Cropped text[edit]

@Arlo Barnes: The cropped-out text can be seen in the original raw scan at IA. For works from the Internet Archive, there will be a listing of all files for a work—like this—with an option to browse ZIP archives. The _jp2.zip archive will the post-processed scan page images and is the best place to go for extracting illustrations and such (since the page images in the DjVu are often more compressed). The _raw_jp2.zip archive is the raw unprocessed scan images and is where to look if the page is garbled in some way, like on this page, since the corruption may have happened during post-processing. Case in point, on this page the post-processing excessively cropped the page and nobody noticed. --Xover (talk) 06:22, 22 October 2019 (UTC)[reply]

Wow, 5010×3336, I had no idea they got cropped so much. I used imagemagick (which uses the Jasper library for JPEG 2000) to convert the JP2 into a PNG for more comfortable viewing. Arlo Barnes (talk) 21:54, 22 October 2019 (UTC)[reply]
@Arlo Barnes: Note that for interactive display the Internet Archive also provides regular JPEGs of these images if the JPEG 2000 files are inconvenient. The downloaded ZIP archives still come with .jp2 files though. PS. for images that are or are similar to photographs, JPEG generally does a better job than PNG and so we generally prefer that in those cases. Not a big concern so long as the resulting image looks good, but all else being equal… --Xover (talk) 04:09, 23 October 2019 (UTC)[reply]
