The escape sequence for unicode characters is - - #[nnn] - -where nnn can be decimal or hexadecimal. Escape sequences are also defined -to change fonts mid-string. - -There are known bugs for our unicode font implementation that are listed in -a special section of the PROBLEMS file, but the current implementation is -good enough so we turn on unicode support by default for the psc, ps, png, -gif, jpeg, and gcw devices. Although all examples look better with unicode -fonts, the new PLplot unicode capabilities are especially demonstrated in -examples x23 and x24. (The latter example requires special fonts to be -installed and at run time environment variables have to be set to access -them, see the self-documentation of the example 24 source code). - - -2.1.2 Extended cmap0 support. - -There have been many updates to cmap0 handling in the effort to wipe away all -vestiges of the old 16 color limit. The theoretical limit should now be 2^15 -colors, since the metafile and tk drivers use a short for communication of the -cmap0 index. Should be *plenty* for the given application, i.e. fixing colors -for lines, points, labels, and such. - -Since both the metafile & tk data stream formats have changed due to the -change from U_CHAR -> short for cmap0 index representation, the format -versions have been upgraded.

Several now present TrueType or PostScript fonts by -default, which produces higher-quality output than in the past: see the -examples from the GD (png) driver on the PLplot Web site at -http://plplot.sourceforge.net/examples/index.html . - - -2.2.1 PostScript - -The PostScript driver is unicode-enabled, and Type 1 PostScript fonts are -used by default. Although the Type 1 symbol fonts do have a significant -number of mathemetical symbols available some key special symbols (squares, -triangles) are missing so that by default Hershey fonts are used to produce -the symbols generated by calls to "plpoin" and "plsym" while PostScript -fonts are used for calls to PLplot routines that plot text strings (e.g., -"plmtex"). If you prefer a pure Hershey font environment, specify -drvopt -text=0, and if you prefer a pure Postscript font environment, specify --drvopt hrshsym=0. - -Tranforms to the text (i.e., rotations, shears) -have been dramatically improved, and the PostScript driver now produces -"publication quality" output with the default PostScript fonts for text -and Hershey fonts for special symbols. - - -2.2.2 GD (png, jpeg, gif) - -The GD driver is unicode-enabled, and uses TrueType fonts by default. The -examples on the PLplot Web site at -http://plplot.sourceforge.net/examples/index.html were produced using this -driver. - - -2.2.3 GCW "Gnome Canvas Widget" - -The GCW "Gnome Canvas Widget" is a new driver that provides PLplot output in -a tabbed Gnome window. It can alternatively be used to drive a special -widget called the PlplotCanvas that can be embedded in Gnome applications. -The driver, associated widget, and specialized API are fully documented in -the PLplot Programmer's Reference Manual in the sections titled "The GCW -Driver" and "Embedding Plots in Gnome/GTK Applications", respectively. - -The GCW driver is unicode-enabled, and uses TrueType fonts by default. - -Special examples that demonstrate the use of the PlplotCanvas are provided -for both the C and Python programming languages. - -To install the GCW driver, use the "--enable-gcw" option during the -configure step of the install process. - -For more information on GTK, see http://www.gtk.org/ . - - -2.2.4 AquaTerm (Mac OS X) - -AquaTerm is a new driver that provides PLplot output in the AquaTerm -graphics terminal program. Aquaterm is a native Cocoa graphics terminal -program for Mac OS X that provides a familiar look and feel to Mac users. -More details about AquaTerm and how to install it can be found at -http://aquaterm.sourceforge.net/. - -The driver is unicode-enabled, however it currently only supports the -default OS X fonts which are not TrueType. - -To install the AquaTerm driver, use the options "--disable-dyndrivers" and -"--disable-f77" during the configure step of the install process. - - -2.2.5 Tk - -The plframe widget (and by extension, the Tk driver) now saves a plot using the -correct aspect ratio, as represented by the actual window size.
