[Plplot-general] Plplot + octave question/problem

[Jonathan B. B. <jon...@dy...>]

Hello plplot-general,

I've just installed plplot 5.5.2 and Octave on a Redhat Linux 9 system.

The compile options for plplot are:

./configure --enable-octave --disable-tk --disable-tkwin --with-freetype \
            --with-freetype2-incdir=/usr/include/freetype2            \
            --with-freetype-font-dir=/usr/local/freettf/sfd


I have the freefont ttf files installed in /usr/local/freettf/sfd

When I run the plplot test program using the following command:
./plplot-test.sh --device=png --front-end="octave"


I get the following errors and warnings:


*** PLPLOT WARNING ***
Too many colours in cmap0.

*** PLPLOT ERROR ***
plscol0: Illegal color table value: 136, aborting operation

*** PLPLOT ERROR ***
plscol0: Illegal color table value: 151, aborting operation

*** PLPLOT ERROR ***

*** PLPLOT ERROR ***

What do these messages mean, and do I have to worry about them?

Thanks in advance.

There is a known problem with the gd.c devices (png, jpeg, and gif) if
colour map 0 is changed in the middle of a plot. This happens in example 2
which is why running that example as part of plplot-test.sh generates all
the error messages.  We are still puzzling out a solution. Until we get a
fix in place, I think you should be all right if you avoid changing the
color map in the middle of a plot when you use -dev png.
