| Class | Description |
|---|---|
| FontRenderContext | The FontRenderContext class is a container for the information needed to correctly measure text. |
| GlyphJustificationInfo | The GlyphJustificationInfo class represents information about the justification properties of a glyph. |
| GlyphMetrics | The GlyphMetrics class represents information for a single glyph. |
| GlyphVector | A GlyphVector object is a collection of glyphs containing geometric information for the placement of each glyph in a transformed coordinate space which corresponds to the device on which the GlyphVector is ultimately displayed. |
| GraphicAttribute | This class is used with the CHAR_REPLACEMENT attribute. |
| ImageGraphicAttribute | The ImageGraphicAttribute class is an implementation of GraphicAttribute which draws images in a TextLayout. |
| LayoutPath | LayoutPath provides a mapping between locations relative to the baseline and points in user space. |
| LineBreakMeasurer | The LineBreakMeasurer class allows styled text to be broken into lines (or segments) that fit within a particular visual advance. |
| LineMetrics | The LineMetrics class allows access to the metrics needed to layout characters along a line and to layout of a set of lines. |
| MultipleMaster | The MultipleMaster interface represents Type 1 Multiple Master fonts. |
| NumericShaper | The NumericShaper class is used to convert Latin-1 (European) digits to other Unicode decimal digits. |
| NumericShaper.Range | A NumericShaper.Range represents a Unicode range of a script having its own decimal digits. |
| OpenType | The OpenType interface represents OpenType and TrueType fonts. |
| ShapeGraphicAttribute | The ShapeGraphicAttribute class is an implementation of GraphicAttribute that draws shapes in a TextLayout. |
| TextAttribute | The TextAttribute class defines attribute keys and attribute values used for text rendering. |
| TextHitInfo | The TextHitInfo class represents a character position in a text model, and a bias, or "side," of the character. |
| TextLayout | TextLayout is an immutable graphical representation of styled character data. |
| TextLayout.CaretPolicy | Defines a policy for determining the strong caret location. |
| TextMeasurer | The TextMeasurer class provides the primitive operations needed for line break: measuring up to a given advance, determining the advance of a range of characters, and generating a TextLayout for a range of characters. |
| TransformAttribute | The TransformAttribute class provides an immutable wrapper for a transform so that it is safe to use as an attribute. |
