Description of problem: GraphicsMagick is currently compiled with 8-bits support only. Some applications, such as Photivo(.org) rely on 16-bits support in order to process RAW images without quality loss. However, compiling GraphicsMagick with 16-bits support would significantly increase its memory consumption, which can be a problem for most uses of GraphicsMagick (webservers, etc.). How reproducible: Compile photivo with the packaged version of GraphicsMagick. Missing 16-bits support leads to strong image artifacts. Expected results: Proper compilation against a 16-bits GraphicsMagick when its support is required and specified in the spec file.
I assume by 16 bits, you mean a build with QuantumBits=16 per http://www.graphicsmagick.org/FAQ.html ?
Yes. It requires a single line change to the spec file: @@ -106,6 +107,7 @@ %build %configure --enable-shared --disable-static \ + --with-quantum-depth=16 \ --with-lcms \ --with-magick_plus_plus \ --with-modules \

I'm testing the viability of issuing 16bit-enabled builds for fedora< 15 too, still trying to check how that affects abi
Thank you. Is there a way to list all Fedora packages that require GM ? Some people may be unhappy of that switch, affecting in a hidden way their existing applications by the new memory requirements.
