Technical Support Reference Number: 77280
In response to your posting of Friday, 4/21/95:
The error message "Programmer error: destroying a gotten color" is an
internal error message. Users should not see this error message
unless there is a problem with one of The MathWorks' supplied
functions.
We have seen this problem before because of a bug in the M-file blt.m.
This file is located in $MATLAB/toolbox/matlab/graphics. The blt
function is called to transfer from color to black and white; the
problem has occurred when printing a figure which was rendered in
color (specifically, surface plots). The bug appeared in MATLAB 4.0,
and is fixed in MATLAB 4.2c (the current version).
Here is how to fix the bug, if necessary:
Find line 151 in blt.m. It should say
old_colors(1,:) = [];
There is an "end" statement right after that line.
Move
old_colors(1,:) = [];
to *after* the "end" statement.
You may have to contact your system administrator to make this change.
If this change does not fix your problem, or if this description does
not fit your situation, then we need to investigate the problem
further. If you can reproduce the same behavior, please send me the
following information so that I may further investigate this problem:
1) output of the "ver" command in MATLAB
2) platform and operating system where you're running MATLAB
3) the exact steps you take that causes the problem, so that I can try
to reproduce the problem here at my site
If you have further questions regarding this issue, please be sure to
mention the above Technical Support Reference number in your email
response to me.
Sincerely,
Kris Giesing
Technical Support Engineer
