[GRASS-user] problem with d.anaglyph

[Mayeli Sanchez Martinez]

Hi!
I'm trying to make an anaglyph with d.anaglyph using a quickbird image
but I have problems.
The process I use is:
1) Creating a composite image with r.composite
2) Creating a region and a mask  (because I first wanted to try a
smaller fraction)
3) Invoke d.anaglyph (all options are given default and only give name
to the output png) image.
but does not create the image.
If they do it from terminal output image are just colored lines.
I'm using debian grass64.

any of you have used? have had a similar problem?
thanks
