Valery Pipin reported the following warning to me: *** PLPLOT WARNING *** Unrecognized cmap1 format #ff0000 100 0
At first glance that is impossible. The line in question is the last line in cmap1_default.pal, and that is just as perfectly formatted as the other lines in that file. However, a closer look at the code in plctrl.c showed a problematic floating-point test for whether pos[i] (calculated from the above 100 value by converting to double and multiplying by 0.01) was in the range from 0. to 1. I have now fixed that test as of revision 10351 to account for small floating-point errors in the calculation of pos[i]. Valery hasn't yet gotten back to me, but when he does I presume he will tell me that fix worked. This whole issue shows how important it is to run PLplot on a large variety of hardware with different floating point errors so that we find problematic floating-point comparisons like what I just spotted and fixed in plctrl.c. Anyhow, if you have access to PowerPC's, sparcstations, Dec Alphas, IBM mainframes or other non-Intel hardware, now would be a good time to do some thorough checking of PLplot on that hardware.
