This option greatly increases the amount of memory required for decompression, and thus reduces performance both for the server and for clients such as browsers. All three cited test cases use this compression mode. I have uploaded one of the three files with interlacing removed: <http://commons.wikimedia.org/wiki/File:Suikoden_(no_interlace).jpg> As you can see, it works just fine. You can do this with ImageMagick using: convert Source.jpg -interlace none Destination.jpg Omitting the -interlace, i.e. a null convert, also appears to work. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
