Re: [Gnuplot-info] white labels in epslatex terminal

[Thomas S. <t.s...@fz...>]

interesting:
'xdvi' shows black text while 'dvips' produces a postscript
file with white text.

'set term epslatex ... colortext' produces black text - so let's
see if there's a difference between 'traj2.tex' produces with
'blacktext' vs. 'colortext':

the main difference between 'blacktext' and 'colortext' is a
sequence of '\color{black}%' and '\color{white}%' lines within
the '\gplgaddtomacro\gplfronttext{%' section which is not
existing in the 'colortext' case.
after deleting those lines in 'traj2.tex' (produced with 'blacktext')
the text is black.

the bug is in pslatex.trm, the '\color{...}%.' commands shouldn't
be written into the output file directly but into the variable
'tex_current_color' like all other color changing commands.

i've submitted a patch.
