[SOLVED] Problem converting to DDS

[nilsca]

Hi

I'm trying to have image magick generate some DDS graphic - input is DDS - the Image magick output can't be loaded by my two dds viewers - one of them Gimp's dds.exe crashes (gimp 2.8.14):

Code: Select all

Problem signature:
  Problem Event Name:	BEX64
  Application Name:	dds.exe

Sequence (for testing)

# 1 the dds original to jpg - works fine of course
convert 8019.dds 8019.jpg

# 2 the jpg back to dds - critical step generating DDS
convert 8019.jpg 8019-from-jpg.dds

# 3 back to jpg from that dds - works fine for Image Magick actually
convert 8019-from-jpg.dds 8019-from-dds.jpg


The all important 8019-from-jpg.dds ends up being not valid. Image Magick itself has no problem in step 3 though. Am I missing a switch? Is ImageMagick's DDS output compatible to the original's format I'm starting with?

.. reporting back that the dds generated by ImageMagick is actually nicely readable by another tool I've tried - paint.net

So I think I'll check with gimp folks and ddsviewer.com on possible problem in their dds file handling.

Thanks

See http://www.imagemagick.org/script/formats.php and http://www.imagemagick.org/script/comma ... php#define about -defines for DDS. Perhaps there is a define you need to specify to be compatible with those other programs.
