I am using octave at the moment and run in a little limitation:
octave and graphicsmagick are compiled with 8bit 'quantum depth'. This is suboptimal because the function imread and imwrite are limited and thus the input and output data may be limited. (As described here:

Additional info:
I compiled graphicsmagick and octave with the PKGBUILD's from the extra repo with the needed configure change.
I tried to verify that graphicsmagick (compiled with 32qd) don't break other things for example pdf2djvu, it was working in my test case (just one try tbh.).

graphicsmagick updated configure line:
./configure \
--prefix=/usr \
--enable-shared \
--with-modules \
--with-perl \
--with-gs-font-dir=/usr/share/fonts/Type1 \
--with-quantum-depth=32 \

octave updated configure line:
./configure --prefix=/usr --libexecdir=/usr/lib \
--enable-shared --disable-static \
--with-quantum-depth=32 \
--with-umfpack="-lumfpack -lsuitesparseconfig" #

This task depends upon

I am personally in favor of this change, at least for graphicsmagick.
Although I am no octave user, I recally we had a related issue in the past:
If this is fixed I'd be happy to update graphicsmagick to use 32-bit quantum depth.
I'll just leave this bug report open for a few days before taking any action, in case other developers have any comments about this.
