15.5 Font protocol

Description of the Font protocol, Revision 5

Minimal support of this protocol consists in the evaluation of the FONT_CHANGED message. Programs that support one of the (GDOS) attributes text angle, text width, kerning, text slope or the setting of the text size in 1/65536 points should also support the XFONT_CHANGED message, which offers additional information.

With the message FONT_SELECT the font-selector can also be called up by the application. During this the currently set attributes can be passsed as well.

If the application also supports the XAcc-2 protocol, then it can also reveal easily the FONT_ACK confirmation message, and search for font selectors in memory even without an environmental variable.
