Details:
I will submit a changeset having a number of bug fixes in the graphics toolkit
for printing.
1) There are several printf errors whereby a float is passed into an octal
formatted number.
2) There are several strings for the parse options which are incorrectly
accessed using curly parentheses rather than round parentheses.
3) The "mono" setting is passed into the graphics toolkit so that gnuplot can
make the decision about what is format strings to create.
4) I've changed the default setting to "color" for PostScript. I'd much
prefer a printed output that looks similar to what the default figure plot
appears.
5) I've overridden the "png16m" and "pdfwrite" behaviors so that gnuplot does
"png" and "pdf" if possible. I prefer gnuplot doing the "-dpng" option as
opposed to creating an EPS figure and then some translation utility to create
a PNG file. PNG fonts are something more suited for bitmap graphics (easier
to read) than would-be scalable fonts (EPS) transformed to bitmap. The
plot-to-postscript-to-png technique is something that can be done by the user
if they like. I think that the exact implementation of these:
function aliases = gs_aliases ();
## Aliases for other devices: "bmp", "png", "tiff", "tiffn", "pdf",
## "ps", "ps2", "psc", "psc2"
file formats should be done at the toolkit level and not the print() level.
