Description Thibault North 2011-04-25 15:06:56 UTC

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.

Comment 1 Rex Dieter 2011-04-25 15:16:11 UTC

I assume by 16 bits, you mean a build with QuantumBits=16 per http://www.graphicsmagick.org/FAQ.html ?

Comment 2 Thibault North 2011-04-25 15:28:24 UTC

Yes.

It requires a single line change to the spec file:

Comment 6 Rex Dieter 2011-04-28 19:07:07 UTC

I'm testing the viability of issuing 16bit-enabled builds for fedora< 15 too, still trying to check how that affects abi

Comment 7 Thibault North 2011-04-28 21:27:09 UTC

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.

Comment 8 Fedora Update System 2011-05-05 05:09:13 UTC

GraphicsMagick-1.3.12-4.fc15 has been pushed to the Fedora 15 stable repository.  If problems still persist, please make note of it in this bug report.
