set term png tiny
On most systems libgd also provides access to Adobe Type 1 fonts (*.pfa) and
TrueType fonts (*.ttf). You must give the name of the font file, not the name
of the font inside it, in the form "face
{,
pointsize
}".
face
is either the full pathname to the font file, or the first part of a
filename in one of the directories listed in the GDFONTPATH environmental
variable. That is, 'set term png font "Face"' will look for a font file named
either
somedirectory
/Face.ttf or
somedirectory
/Face.pfa.
For example, if GDFONTPATH contains /usr/local/fonts/ttf:/usr/local/fonts/pfa
then the following pairs of commands are equivalent
set term png font "arial" set term png font "/usr/local/fonts/ttf/arial.ttf" set term png font "Helvetica" set term png font "/usr/local/fonts/pfa/Helvetica.pfa"To request a default font size at the same time:
set term png font "arial,11"
Both TrueType and Adobe Type 1 fonts are fully scalable and rotatable. If no specific font is requested in the "set term" command, gnuplot checks the environmental variable GNUPLOT_DEFAULT_GDFONT to see if there is a preferred default font.
