Hi all,
I worked around the problem simply overwriting all colr files bigger
than 32K with a correct one. Now the tiles made by r.patch display as
fast as do the tiles made by r.mapcalc, and no changes in colors are
noticed.
But I still would to know why r.patch makes his work wrong sometimes.
Some months ago, I patched some 80.000 RGB tiles without error.
*Please*, can someone explain it?
Thanks,
Roman
