Detailed Description

FontEnginePlugin is the interface definition for font engine plugins.

Font engine plugins contain both font loaders for creating FontFile objects and shapers. Kanzi uses the shapers to shape text that uses Fonts from the same plugin.

Member Enumeration Documentation

◆ FontEngine

enum kanzi::FontEnginePlugin::FontEngine

strong

Enumeration for different types of font engine (rasterizer library).

Enumerator
MockFontEngine	MockFontEngine does not use a rasterizer and you cannot use it to render text.
FreeTypeFontEngine	FreeTypeFontEngine uses the FreeType rasterizer, HarfBuzz shaper, and ICU bidirectional library, and libunibreak for line breaking.
ITypeFontEngine	ITypeFontEngine uses the Monotype iType rasterizer and WorldType® Shaper™ for shaping.

Member Function Documentation

◆ getEngineType()

virtual FontEngine kanzi::FontEnginePlugin::getEngineType ( ) const

pure virtual

Returns the font engine type that is used by this font engine plugin.

Returns: Type of the font engine.

Implemented in kanzi::FreeTypeFontEnginePlugin, and kanzi::ItypeFontEnginePlugin.

◆ getFontLoader()

virtual FontLoaderPtr kanzi::FontEnginePlugin::getFontLoader ( Domain * domain ) const

pure virtual

Creates a FontLoader object.

Parameters

domain The UI domain to which you want the font family to belong.

Returns: Pointer to the FontLoader object.

Implemented in kanzi::FreeTypeFontEnginePlugin, and kanzi::ItypeFontEnginePlugin.

◆ getShaper()

virtual TextShaperPtr kanzi::FontEnginePlugin::getShaper ( const FontRuntime & font ) const

pure virtual

Creates a TextShaper object.

Parameters

font	The Font that the shaper will use.

Returns: Pointer to the TextShaper object.

Implemented in kanzi::FreeTypeFontEnginePlugin, and kanzi::ItypeFontEnginePlugin.

Member Data Documentation

◆ s_FreeTypeFontEngineName

const string kanzi::FontEnginePlugin::s_FreeTypeFontEngineName

static

Name of the FreeType font engine plugin.

Kanzi uses this name to automatically search and register font engine with this name to be available to the font manager.

◆ s_iTypeFontEngineName

const string kanzi::FontEnginePlugin::s_iTypeFontEngineName

static

Name of the iType font engine plugin.

Kanzi uses this name to automatically search and register font engine with this name to be available to the font manager.
