Formats other than PNG might be more appropriate, yes. > http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557238 This one (vtk-doc) doesn't compress PNGs, but reduces their quality in a lossy way to 256 colours. And in this case, using optipng+advpng would reduce the files by more than a half (comparing sizes of .tar.xz). -- ᛊᚨᚾᛁᛏᚣ᛫ᛁᛊ᛫ᚠᛟᚱ᛫ᚦᛖ᛫ᚹᛖᚨᚲ -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
