Hiya Curt and Kurt...  ;)

It sure is an RPM issue, the QuantumDepth has not been set in GraphicsMagick.

The latest source of GraphicsMagick allows ./configure
--with-quantum-depth=16 however it has problems with Perl so nearly there.
Installed the latest version of Perl, 5.10.0 via YUM UPDATE (Fedora 9).

However a 'make' of GraphicsMagick complains of a missing file in the
directory below called 'libperl.a' and fails.

/usr/lib/perl5/5.10.0/i386-linux-thread-multi/CORE/

This file IS there: 'libperl.so' so copied it to 'libperl.a', make clean,
then make again and all OK.

Recompiled Xastir and all graphic functions are back to normal.

ImageMagick is OK:

 /usr/lib/ImageMagick-6.3.8/config/configure.xml

 <configure name="QuantumDepth" value="16"/>

Best to 'rpm -e GraphicsMagick GraphicsMagick-devel' prior make install of
the latest source which is available from GraphicsMagick.org

Thanks to all and regs, Rod.
