[19:05:00] hi [19:05:11] Please, someone could take a look to https://commons.wikimedia.org/wiki/File:DSC_8200-Pano.tif [19:05:22] its like a thumbnail generation server side problem [19:09:49] I mean, the image is a 1.82GB TIF [19:10:37] RAW file formats are very recomended for scans and films and its a normal size for a TIFF [19:11:13] Well, sure [19:11:25] But that doesn't mean we'll necessarily thumbnail it [19:11:35] same as we don't for images over 100MP [19:12:19] Slightly surprising it's not seemingly pulled out any of the metadata [19:13:51] It looks like MW knows it's too big and just hasn't bothered, based on https://commons.wikimedia.org/w/resources/assets/file-type-icons/fileicon.png being provided [19:13:55] Rather than it happening and failing [19:19:07] ? [19:19:27] ? [19:19:56] what do you mean with "It looks like MW knows it's too big and just hasn't bothered..." [19:20:36] It decided to not try, rather than trying and failing. [19:20:53] based on the size [19:21:10] I see [19:23:10] It looks a lot like tiffinfo doesn't extract the metadata properly [19:23:23] Now I am wondering.. EXIF data can contain a thumbnail. Maybe if you create that before upload and it's in there, would MW use it? [19:23:26] trying it locally, it seems to spew most of the file contents too, so indeed thinks it's too large [21:41:14] mutante, Have not checked for MediaWiki itself, but Thumbor won't on Wikimedia sites [21:42:18] And yes, the problem with that file is that tiffinfo isn't extracting the metadata properly [21:42:52] if MediaWiki thinks that the file is 0x0 px, it won't bother trying to thumbnail it at all and displays the default icon [21:44:23] #upstream [21:44:48] https://upload.wikimedia.org/wikipedia/commons/thumb/6/6a/DSC_8200-Pano.tif/220px-DSC_8200-Pano.tif.jpg [21:45:23] Thumbor works independently of MediaWiki, so thumbnail generation itself works fine [21:49:34] `tiffinfo DSC_8200-Pano.tif` gives two errors then starts spewing hex at me, that's always fun [21:50:45] it looks like it's trying to output the whole file in hex to the console [21:50:56] AntiComposite: thanks! [21:51:31] sounds like if you can delete metadata then it might work? [21:53:05] `TIFFReadDirectory: Warning, Unknown field with tag 37724 (0x935c) encountered.` is likely the important error [21:53:56] https://gitlab.com/libtiff/libtiff
