.TH Fonts PL "17-SEP-2001   PL www.sgpr.net"

.SH What fonts are available?
.LP
This depends on what output format you are producing, since
Ploticus does not include its own internal fonts.

.ig >>
<br><br><br>

.SH PNG, GIF, etc.
If the default built-in GD code is used, a basic ascii font is
available in 5 sizes (you can specify any point size in ploticus; the nearest
available size will be used).
You can't set the font from ploticus; \fC-font\fR (etc.) will have no effect.
Vertical rendering is available.
Availability of symbols and nonroman characters is limited to those in ASCII
128-255.

.SH PNG, JPEG, WBMP with FreeType2 support
If your ploticus build uses GD with FreeType2
support, you can use TrueType fonts.
The basic GD ascii font is also available in 5 sizes, and is the default
(its name is \fCascii\fR should you need to use it explicitly).
You can set the font from ploticus using \fC-font\fR,

attribute.
TrueType font names should be given without the .ttf extension, 
e.g. if you have a font file called times.ttf you would use 
.IP
\fC-font times \fR
.LP
You will need to have some TrueType .ttf font files stored in a directory somewhere.  
The environment variable \fBGDFONTPATH\fR must be 
set to contain the pathname of this directory.
TrueType font files may be found on NT machines in 
\fCc:/winnt/fonts\fR or they may be downloaded on the web.  
.LP
Vertical rendering is available.  
Availability of symbols and nonroman characters:
UTF-8 sequences such as \fC&#192\fR may be used.

Usually these fonts are available: \fC/Helvetica /Helvica-Oblique /Helvetica-Bold

usually available as well.

.SH X11
Always uses the same fixed width font.  
You can't set the font from ploticus; \fC-font\fR (etc.) will have no effect.
Depending on availablility, this will be
either \fC-adobe-courier-bold-r-normal\fR, \fC-misc-fixed-medium-r-normal\fR, 
or as a last resort, \fC9x15\fR.  Proper vertical rendering is not available.
Availability of symbols and nonroman characters is limited to those in ASCII
128-255.
