Dear Agus!
I'm trying to test the new 24 bit
driver, which should be an important improvement
for us.2 questions:
1. Once we have the new bins, d.mon start=x0 opens
the graphic window along with the following message:got a TrueColor (Read-Only!) Visual
ncolors: 32768
allocating memory...
Graphics driver [x0] startedIs this number of colors what should be expected?
Yes, this is the ncolors if no further parameter is
specified. To get *more* colors use:
d.mon x0 nlev=256
got a TrueColor (Read-Only!) Visual
ncolors: 16777216
allocating memory... [takes time]
Graphics driver [x0] started
The new nlev parameter defines the number of color levels per
channel.
2. Should the output of d.rgb have 24-bit color resolution?
(was the example in the web produced with d.rgb?)
Yes, it should. Here the composites' quality is much better
than before.
The web example was a plain d.rast output. In in recently
published GRASS 5 beta3 you find "r.in.ppm" updated to import
true color ppm images (before colors were limited to 32768).
Just now I have received r.in.tiff updated to 24bit as well.
It will be published in the forthcoming GRASS 5beta4 soon.
Best regards
Markus Neteler
