Ilmari Karonen <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Ilmari Karonen <[email protected]> 2010-07-02 13:25:20 UTC --- This would require either patching ImageMagick to use less memory when scaling such images (which may ultimately require patching libjpeg) or switching to a different image scaler. In principle, there's no reason why downscaling an image in any format couldn't be done using space (at most) proportional only to the size of the target image, not of the source. However, this requires being able to read and decode the source image data without buffering it all in memory. For progressive JPEGs this would mean scaling each pass as it is read, and only combining them after scaling. I'm not aware of any existing image scaler that would do this, but then, I haven't really looked, either. If anyone knows of a program that does this and otherwise fits our needs (i.e. open source, usable from the command line, actively maintained, etc.), please tell us so we can evaluate it. It would also be even more useful to have such a scaler for PNG images. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
