Hello,
Commons received this offer on its Village pump recently:
<quote> == PNG images not thumbnaling to JPG == As discussed [[Commons:File_types#Images|here]], "thumbnails are generated in the same format as the original image and are always in 24-bit color ...".
Obviously the reason this issue still exists is because some images should by all means be thumbnailed to PNG (line art, comics, maps, etc), and would suffer from JPEGification. However, as also pointed out on that page, this discourages people from uploading PNGs, which are particularly favourable for long-term archival purposes.
I have some background in digital imaging and watermarking, and could probably throw together a set of scripts and programs in a month's spare time to algorithmically analyse candidate images and determine how they should be thumbnailed. The issue of properly handling greyscale images would also be handled.
But of course, I don't want to start on this, only to find out later that it's rejected for some reason <tt>:-)</tt>.
Is this something the Wikimedia community would find useful? </quote>
What is necessary for his work to be useful, and used, in MediaWiki?
