Description Maarten Dammers 2012-10-17 18:53:03 UTC
At the moment Tiff files are only rendered if the file is 12.5 megapixels or less. This limit has been in place for quite some time and has proved to be sufficient for quite some files, but the limit is too low for a lot of other files.

Please raise the limit to 25 megapixels. This covers most files from GLAM/archival sources.
Comment 1 Maarten Dammers 2012-10-17 19:09:23 UTC
Talked with Duesentrieb and Reedy about this on irc.

Tiff rendering is done by . It contains "$wgTiffMaxEmbedFileResolution" but that doesn't seem to be set anywhere.

It looks like$wgMaxImageArea is the one that would need to be raised.
Comment 2 Sam Reed (reedy) 2012-10-17 19:14:38 UTC
Increase $wgMaxImageArea to 1.4e7...
Comment 3 Maarten Dammers 2012-10-17 20:04:15 UTC
Sam raised the limit on test to 2.5e7 and now renders properly.
Comment 4 Dominic 2012-10-17 21:24:07 UTC
Since we are raising the megapixel limit, it would be nice to see some movement on bug 29967 to make these large files more friendly to users.
Comment 5 Maarten Dammers 2012-10-18 19:36:47 UTC
Updated the title to what I think needs to happen (raise $wgMaxImageArea).
Comment 6 Sam Reed (reedy) 2012-10-21 01:32:36 UTC
Up to 20 on the cluster... No problems seemingly noticed so far!

Comment 8 Andre Klapper 2012-10-30 16:17:41 UTC
See bug 41511 for followup fallout.
