GlyphRun Class

Definition

Represents a sequence of glyphs from a single face of a single font at a single size, and with a single rendering style.

Remarks

The GlyphRun object includes font details such as glyph indices and individual glyph positions. In addition, The GlyphRun object contains the original Unicode code points the run was generated from, character to glyph buffer offset mapping information, and per-character and per-glyph flags.

The Glyphs element represents the output of a GlyphRun in XAML. The following markup syntax is used to describe the Glyphs element.
