Specify the font used for drawing the INCOMMENT and OUTCOMMENT text.
Fonts are specified by number. The GD library that Weathermap uses has 5 built-in fonts, 1-5. You can define new fonts based on TrueType or GD fonts by using the FONTDEFINE directive.
For Link Comments, you must define a TrueType font. These are the only font that can rotate text through any angle, as required by comments. You can change the colour used to render the font with COMMENTFONTCOLOR
