At this point Dillo supports the display of GIF, PNG, and JPG, but SVG is used heavily by sites like, for example, Wikipedia. Has the Magick++ library in ImageMagick been considered for supporting these other image formats? The FLTK people seem enthusiastic about the Imago library in spite of its alpha state of development; librsvg, which looks, at least to my untutored eye, like it requires a fair amount of voodoo to use, is apparently no longer actively supported and would at any rate only provide SVG support; but ImageMagick is pretty standard with Linux distributions, and the Magick++ interface makes conversions from any format to PNG for the purposes of display extremely easy. In src/misc.c, at the end of the image part of the else-if ladder in a_Misc_get_content_type_from_data(), one could add another "rung" that uses Data and Size to create a Magick::Blob, and from this a Magick::Image, then use Magick::Image.write() to write this to another Magick::Blob of type PNG, and then replace Data and Size with those of the resulting Magick::Blob. A try-catch block would catch the cases where Data is not an image. Altogether this sort of "cheat" would require very few lines of code to implement. And the Magick++-config utility could supply the needed -D..., -I..., -l... flags to the configure script. I'm not suggesting this is an ideal long-term solution, but in the interim would at least allow the display of other image types. The most recent mention of this on the mailing list seems to be Jorge's indication on 22 April 2016 that No, there's no SVG image support in dillo yet. It should not be hard to implement though, but it needs an effort similar to GIF or PNG or JPEG code. Patch welcomed! ;) But surely someone has thought of ImageMagick before. Are there objections to using it? And if so, maybe a flag could be set by the configure script to conditionally compile this in for those who want it? (If this is pursued, the configure script should probably also check that the version of ImageMagick is recent enough to have been patched against that serious exploit in just this sort of conversion code.) A test program shows that the invocation of ImageMagick and conversions really are as simple as the steps outlined above. But I would be happy to make an attempt at a patch, if you don't mind this being undertaken by an amateur.
