Description Dominic 2014-03-09 23:36:40 UTC 
This is a bug report to determine whether we can raise the megapixel limit for images higher than the current 50 MP limit. This would better support high-quality archival scans and other complex media.

According to data from Tim Landscheidt (http://tools.wmflabs.org/wikilint/50mps.csv), there are currently over 20,000 files that break the megapixel limit in Wikimedia projects, which results in a thumbnail error that makes them unusable except for downloading. Roughly, raising the limit to 200 MP would fix all but the top-1000 highest-resolution images. Raising it to 100 MP would fix all but the top 5000.

I have no idea how these changes might affect site performance, though. Thoughts?

It seems VipsScaler has to be applied to GIF and TIFF, first. (Already done for PNGs)
* TIF: bug 52045
* GIF: bug 52043

It seems the limit for GIF is 12,5 MP although $wgMaxAnimatedGifArea is set to 50MP. Seems Bug 61711
