IDWriteFontFaceReference Represents a reference to a font face. A uniquely identifying reference to a font, from which you can create a font face to query font metrics and use for rendering. A font face reference consists of a font file, font face index, and font face simulation. The file data may or may not be physically present on the local machine yet.
IDWriteFontFaceReference1 Represents a reference to a font face. A uniquely identifying reference to a font, from which you can create a font face to query font metrics and use for rendering.
IDWriteFontFallback Allows you to access fallback fonts from the font list.

IDWriteFontFamily Represents a family of related fonts.
IDWriteFontFamily1 Represents a family of related fonts.
IDWriteFontFamily2 Represents a family of related fonts. IDWriteFontFamily2 adds new facilities, including retrieving fonts by font axis values.
IDWriteFontFile Represents a font file. Applications such as font managers or font viewers can call IDWriteFontFile::Analyze to find out if a particular file is a font file, and whether it is a font type that is supported by the font system.
IDWriteFontFileEnumerator Encapsulates a collection of font files. The font system uses this interface to enumerate font files when building a font collection.
IDWriteFontFileLoader Handles loading font file resources of a particular type from a font file reference key into a font file stream object.
IDWriteFontFileStream Loads font file data from a custom font file loader.
IDWriteFontList Represents a list of fonts.

IDWriteTextAnalysisSource Implemented by the text analyzer's client to provide text to the analyzer. It allows the separation between the logical view of text as a continuous stream of characters identifiable by unique text positions, and the actual memory layout of potentially discrete blocks of text in the client's backing store.
IDWriteTextAnalysisSource1 The interface you implement to provide needed information to the text analyzer, like the text and associated text properties.
IDWriteTextAnalyzer Analyzes various text properties for complex script processing such as bidirectional (bidi) support for languages like Arabic, determination of line break opportunities, glyph placement, and number substitution.
IDWriteTextAnalyzer1 Analyzes various text properties for complex script processing.
IDWriteTextAnalyzer2 Analyzes various text properties for complex script processing.
