Constructor & Destructor Documentation

ion::text::StaticFontImage::StaticFontImage ( const FontPtr font,
size_t  max_image_size,
const GlyphSet glyph_set 
)

The constructor sets up the single ImageData instance to contain glyphs for all the requested glyphs.

StaticFontImage functions.

If the Font is not valid, the glyph set is empty, or the resulting image would exceed max_image_size in either dimension, the ImageData instance will be empty.

Definition at line 473 of file fontimage.cc.

ion::text::StaticFontImage::StaticFontImage ( const FontPtr font,
size_t  max_image_size,
const ImageData &  image_data 
)
protected

Protected constructor for MockFontImage that bypasses normal processing and allows ImageData to be set directly.

Member Function Documentation

const FontImage::ImageData & ion::text::StaticFontImage::FindImageData ( const GlyphSet glyph_sets)
overridevirtual

Implements this function to return the single ImageData instance, whether or not it contains all the requested glyphs.

You can use HasAllGlyphs() to test whether all of the glyphs appear in the ImageData, or use HasGlyph() or GetTextureCoords() to test individual glyphs.

Implements ion::text::FontImage.
