Using the Font Manager

The Font Manager describes how you can use fonts in general and TrueType

fonts specifically. There are certain guidelines you should consider when

integrating fonts into your application-for instance, how to show which point

size is currently selected and how to make sure that the font used in a document

is the same on different computer systems. If you want to take best advantage

of TrueType fonts, your application should be aware of how TrueType glyphs

may behave differently than bitmapped glyphs.

To determine whether your application can use TrueType fonts on a user's

computer system, call the Gestalt function with the selector

gestaltFontMgrAttr. If the Gestalt function returns noErr and bit 0 of the

response ( gestaltOutlineFonts) is 1, outline fonts are present in the system

software. (See the Compatibility Guidelines for more information on the

Gestalt function.)
