Qtopia Core Fonts

Qtopia Core uses the FreeType 2 font engine to produce font output. For this reason it supports the same font formats as this font engine. In addition, Qtopia Core supports the Qt Prerendered Font (QPF), a light-weight non-scalable font format specific to Qtopia Core. Several of the formats may be rendered using anti-aliasing for improved readability on low-resolution devices.

When Qtopia Core applications run, they look for a file called fontdir in Qtopia Core's /lib/fonts/ directory. This file defines the fonts that are available to the application (i.e. the fonts located in the /lib/fonts/ directory), and can be modified to specify the preferred fonts.

Support for other font formats can be added, contact info@trolltech.com for more information.

• FreeType Formats
• Qt Prerendered Font
• Specifying Fonts

Optimization Both the FreeType and QPF formats are features that can be disabled using Qtopia Core's feature definition system, reducing the size of Qt and saving resources. Note that at least one font format must be defined. See the Fine-Tuning Features in Qtopia Core documentation for details.

All supported fonts use the Unicode character encoding. Most fonts available today do, but they usually don't contain all the Unicode characters. A complete 16-point Unicode font uses over 1 MB of memory.

Warning: The font definition file, naming conventions for the font files, and the format of QPF files may change in future versions of Qtopia Core.
