Re: [Gnuplot-info] png terminal will not print different font size except for the default

[BBands <bb...@gm...>]

There is quite a bit of info on gd here:

http://www.boutell.com/gd/manual2.0.33.html

Many have moved on from gd for png support, so help may be hard to come by.

Here is a snippet from the 4.6 release note:

The 4.6 source code supports three primary cross-platform output modes
in addition to several platform-specific modes.

1) Cairo/pango/wxWidgets
   These terminals were introduced in version 4.4 and are now the most
   stable and full-featured option.  This set of terminals includes
   - pngcairo, pdfcairo, epscairo, and cairolatex for output to a file
   - wxt for interactive display
   This is the default configuration, but requires prior installation of
   libcairo, libpango, libcairo, libwxgtk, and related support libraries
   To disable these terminals:
       ./configure --disable-wxt --without-cairo

2) Qt
   The new qt terminal supports interactive display with menu-driven
   output to png, svg or pdf.
   Requires libqt version >= 4.5
       ./configure --enable-qt
