Using the same source image as my tests in bug 23258, except pre-converted to PNG, the memory usage was 18MB for VIPS, and 411MB for ImageMagick. Memory usage in VIPS was low even if I used interlaced encoding in the source image. Note that im_tiff2vips and im_jpeg2vips are also marked "WIO", but reading TIFF and JPEG images uses a small amount of memory nonetheless. I think file format handlers are a special case. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
