elements, C<TITLE> for the title, C<AXIS> for the axis labels, C<UNIT>
for the vertical unit label, C<LEGEND> for the graph legend.
-Use Times for the title: C<--font TITLE:13:/usr/lib/fonts/times.ttf>
+Use Times for the title: C<--font TITLE:13:Times>
If you do not give a font string you can modify just the sice of the default font:
C<--font TITLE:13:>.
If you specify the size 0 then you can modify just the font without touching
the size. This is especially usefull for altering the default font without
-resetting the default fontsizes: C<--font DEFAULT:0:/usr/lib/fonts/times.ttf>.
+resetting the default fontsizes: C<--font DEFAULT:0:Courier>.
RRDtool comes with a preset default font. You can set the environment
variable C<RRD_DEFAULT_FONT> if you want to change this.
-Truetype fonts are only supported for PNG output. See below.
+RRDtool uses Pango for its font handling. This means you can to use
+the full Pango syntax when selecting your font:
+
+The font name has the form "[I<FAMILY-LIST>] [I<STYLE-OPTIONS>] [I<SIZE>]",
+where I<FAMILY-LIST> is a comma separated list of families optionally
+terminated by a comma, I<STYLE_OPTIONS> is a whitespace separated list of
+words where each WORD describes one of style, variant, weight, stretch, or
+gravity, and I<SIZE> is a decimal number (size in points) or optionally
+followed by the unit modifier "px" for absolute size. Any one of the options
+may be absent.
[B<-R>|B<--font-render-mode> {I<normal>,I<light>,I<mono>}]
+(this gets ignored in 1.3 for now!)
+
This lets you customize the strength of the font smoothing,
or disable it entirely using I<mono>. By default, I<normal>
font smoothing is used.
[B<-B>|B<--font-smoothing-threshold> I<size>]
+(this gets ignored in 1.3 for now!)
+
This specifies the largest font size which will be rendered
bitmapped, that is, without any font smoothing. By default,
no text is rendered bitmapped.
[B<-i>|B<--interlaced>]
+(this gets ignored in 1.3 for now!)
+
If images are interlaced they become visible on browsers more quickly.
[B<-g>|B<--no-legend>]
at least one print statement to generate a report.
See L<rrdgraph_graph> for the exact format.
+=item Markup
+
+All text in rrdtool is rendered using Pango markup. This means text can contain embeded markup instructions.
+Simple html markup using
+
+ <span key="value">text</span>
+
+can be used. Apart from the verbose syntax, there are also the following short tags available.
+
+ b Bold
+ big Makes font relatively larger, equivalent to <span size="larger">
+ i Italic
+ s Strikethrough
+ sub Subscript
+ sup Superscript
+ small Makes font relatively smaller, equivalent to <span size="smaller">
+ tt Monospace font
+ u Underline
