DDS quality, filtering

I'm using ImageMagick (command line tool) under osx.
I don't see any quality improvement when using dds:cluster-fit=true. The compression is pretty bad compared to other tools. But I would like to use ImageMagick since it far more flexible.
This is the command I'm running:

Code: Select all

convert input.png -flip -define dds:compression=dxt5 -define dds:cluster-fit=true output.dds
Anyone else seeing this?
Is there any workaround to get better quality out of compressed dds files?

Thanks.

It seems I made a mistake in the dds writer. The 'dds:cluster-fit' option does nothing at the moment. I will submit a patch so this will fixed in ImageMagick 6.8.8-8.

Thats good news, thanks!

When will the binaries for 6.8.8-8 be available for download? :)
