if gdal supplies a color table it uses it, otherwise r.external checks
if the map is type GDT_Byte and if so applies the grey255 rules. Or, if
some other data type applies G_make_grey_scale_colors() based on
headdesk
Thanks!
The handling of overlapping areas is the reason I keep recompiling the
older version of v.buffer as v.oldbuffer. This lets me use the old debug
flag to prevent it from cleaning the areas, which I can then turn into
discrete areas instead of having them combined by the newer

Hi all.
Just ran r.clump, no options, and it obviously misses some areas (those
at the bottom). It only finds 932 areas in my case, 1038 in other
machines. Could someone check if it's a general phenomenon, before
opening a ticket?
Thanks.

Explained: the areas are there, it's just the color
Hi everyone,
I could solve this problem like this:
First: read the rows and columns of your raster map using r.info. Appropiate
sample intervals are obtained by dividing that number by 100.
For example, if you have:
Rows: 7603
It seems to me a minor bug, right?
All the best.
Ticket created (#1598).
Thanks.

Markus,
i do have the grass6_dev package. is that different from grass-dev?
FYI these are the messages i get after
*./configure --with-grass6=/usr/local/grass-6.5.svn*
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
As always, thanks to everyone for helping fix even simple errors!

When I try to open GRASS-6.4.2.app (paper, pencil, ruler and brush icon) I
get a very brief flash of the familiar icon, grass in a diamond, but
nothing

That looks like Michael Barton's package. We both use the same base
frameworks. And we both bundle wxPython in the application so there is no need
to download and install that (it will be ignored by GRASS).
The invalid context error should be harmless.
Certainly make sure the frameworks are
If you downloaded these from my site, take a look at the readme text file in

Good luck, if you succeed please let us know.
All the best.
