Detailed Description

The GlsRuntimeFontBase class provides a specific font face for use within the GL Studio. The font face is determined at construction time by the parameters passed in by the creator of the GlsFontBase instance. Specific instances should be wrapped in a singleton object wrapper, as there is no reason to have more than one instance of the exact same face (meaning font family, style, and point size.)

Once instanced, a GlsFontRenderer object can be used to render characters in Open GL at specific locations and with several different text effects.

Constructor & Destructor Documentation

GlsRuntimeFontBase ( const char *  family,
const char *  style,
const unsigned int  ptSize,
const char *  fontPath,
const unsigned int  maxCharWidth,
const unsigned int  maxCharHeight,
const unsigned int  descender 
)

Class Constructor

Parameters
familythe family name of the font.
stylethe style name of the font.
ptSizethe point size of the font.
fontPaththe path and filename of the font file to load.
maxCharWidththe maximum width of the largest character.
maxCharHeightthe maximum height of the largest character.
descenderthe maximum descender of the largest character.
~GlsRuntimeFontBase ( )
protected

Class Destructor. This is protected so that no one can delete a font except via the font manager GlsFontMan. It is not virtual because we want to avoid calling destructors on unloaded font code, and it is not needed.

Member Function Documentation

const CharAttrRuntime_t& CharAttrRuntime ( Char_t  c) const

Gets the runtime character attribute for the given char

Parameters
cThe character to retrieve attributes for.
Returns
The attributes for the character else char attributes for first character in font if char is not in range for this font
RuntimeGlyphGenerationFont* GetRuntimeGlyphGenerationFont ( )

Gets a pointer to the internal data needed for runtime glyph generation.

Returns
A pointer to the internal data needed for runtime glyph generation.
bool IsValid ( void  ) const

Determine if font was instantiated correctly

Returns
true if valid else false
