bug#12960: 24.3.50; etc/images/splash.svg is displayed inside GNU Emacs black and white

[Peter Dyballa]

Hello!

SVG images appear in different colours inside GNU Emacs, as displayed  
by ImageMagick's display or as displayed in a PDF viewer after  
conversion to PDF, with svg2pdf. It's not clear what the cause is.  
Maybe it's the MSB format of the PPC platform.

Regarding etc/images/splash.svg it's displayed as PDF in the same  
colours as the PNG variant while display uses wrong colours (light  
grey for the gnu, some brown-red-grey mix for the Emacs text). I'll  
have to report this as an ImageMagick bug…

bug#12960: Acknowledgement (24.3.50; etc/images/splash.svg is displayed inside GNU Emacs black and white)

[Peter Dyballa]

The NS variant, not using ImageMagick but librsvg2, displays etc/ 
images/splash.svg in the correct colours.

The case seems to be solved: I have two ImageMagick installations, one  
from the Fink package manager and one from the MacPorts package  
manager. The former one produces the black&white view, the other  
produces the false-colours view. Both are version 6.8.0-2. Since on my  
intel system (with Mac OS X 10.6.8, Snow Leopard) the presentation is  
OK, so it's probably caused by the byte order on my PowerPC system  
with Mac OS X 10.5.8/Leopard (and maybe as well 10.4.11/Tiger).
