(continued)
I have now recovered the mail archive and browsed it for notes on color
tables.
At one stage it is claimed that 256 gray levels could be got in colormode
float.
I though this would be a good test of our problems, so I created colortables
with 256, 215, 205 different grays, as well as a few others. TO check up on
things I used xshowcmap to show the active colortable - this is a good tool
as it changes dynamically when you allocate more colors. Unfortunately this
confirmed the problem - in colormode float I get 16 (colorful) colors at the
top of the table (grass's default colors? or the vector colors?) and then just
49 grey levels, no matter what! Is the Xdriver routine for filling the color
table really that ineffective? Or am I stuffing up somewhere else?
Thanks
