Grab bag of topics here. The 3rd one is the nasty bug. (1) Maurice brought up turning on dynamic drivers by default earlier. Since nobody has objected, and I think this will be of some benefit to our users, I have just committed the change. (2) I have also done some preliminary runs of plplot-test.sh, and all the many changes today seem to be working well together. (3) I also did a preliminary test of tkdemos.tcl, and found some bad problems with the colour map handling. To generate the problem simply do the following: ./plserver % source tkdemos.tcl 8 the $w cmd plscmap1 rr gg bb $n_col command in x08.tcl (where n_col is been set to 256) is completely incompatible with plframe although this command works fine for tcldemos.tcl (1) plframe.c assumes the incorrect order of arguments. (2) Once the arguments are rearranged, then the limit on n_col must be raised to at least 256. (3) After those changes it still doesn't work. I don't really understand the scol1 programme logic, but to me it looks unsuitable for what is meant by plscmap1 which should just set the colours in cmap1 without worrying about interpolation. Anyhow, I am beyond my depth, and I have backed out without committing anything. Maurice, could you have a look at this? The reason why this was never noticed in 5.0.4 is the x08.tcl example there had no 3D shaded plot. All my testing of the x08.tcl, etc. changes has been under tcldemos.tcl which has absolutely no problems. I didn't really twig to the fact that some of the API calls were intercepted by plframe.c until tonight so I never worried about a tkdemos.tcl test. BTW, all the other tckdemos.tcl tests go through fine except for example 8. Alan email: ir...@be... phone: 250-727-2902 FAX: 250-721-7715 snail-mail: Dr. Alan W.
