I did not generate that command line invocation, so I can't really explain the justification for it. It comes from the thumbnailing code in Gallery, some imageboard software, and probably some other places. It does not seem uncommon, and works as expected (at least, how I expected it to work) in GraphicsMagick. I'm not sure I understand upstream's response, though... is he trying to say that it is expected that the provided example generates a jpg that is tens of thousands pixels wide and tall? Even though the -size and -geometry options specified a size of 217x159? Using -resize instead of -geometry doesn't seem to change this behavior, but '-layers merge' does. > Are you trying to merge all the layer ? something like this : > > convert -resize '217x159!' -layers merge 'foo.gif[0]' foo.jpg The -layers option makes this incompatible with older ImageMagick releases, and GraphicsMagick, which is possibly why various software uses the other invocation. > BTW according to upstream they are no security breach. Reading the referenced link makes me think upstream did not understand what I'm complaining about. While it is certainly reasonable for imagemagick to generate images this large, and the failure mode is understandable, why is imagemagick trying to create such a large image in this case at all? -- Andrew Deason adea...@dson.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
