The interface 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.

| BOOL | isSideways |
| If true, specifies that glyphs are rotated 90 degrees to the left and vertical metrics are used. Vertical writing is achieved by specifying isSideways = true and rotating the entire run 90 degrees to the right via a rotate transform. More... | |
| UINT32 | bidiLevel |
| The implicit resolved bidi level of the run. Odd levels indicate right-to-left languages like Hebrew and Arabic, while even levels indicate left-to-right languages like English and Japanese (when written horizontally). For right-to-left languages, the text origin is on the right, and text should be drawn to the left. More... | |

If any of these callbacks returns an error, the analysis functions will stop prematurely and return a callback error. Rather than return E_NOTIMPL, an application should stub the method and return a constant/null and S_OK.
The interface implemented by the text analyzer's client to receive the output of a given text analysis. The Text analyzer disregards any current state of the analysis sink, therefore a Set method call on a range overwrites the previously set analysis result of the same range.
Analyzes various text properties for complex script processing.
The DWRITE_GLYPH_RUN structure contains the information needed by renderers to draw glyph runs. All coordinates are in device independent pixels (DIPs).
| DWRITE_GLYPH_RUN::_Field_size_ | ( | glyphCount | ) | const |
The indices to render.
| DWRITE_GLYPH_RUN::_Field_size_opt_ | ( | glyphCount | ) | const |
Glyph advance widths.
| DWRITE_GLYPH_RUN::_Field_size_opt_ | ( | glyphCount | ) | const |
Glyph offsets.
| UINT32 DWRITE_GLYPH_RUN::bidiLevel |
The implicit resolved bidi level of the run. Odd levels indicate right-to-left languages like Hebrew and Arabic, while even levels indicate left-to-right languages like English and Japanese (when written horizontally). For right-to-left languages, the text origin is on the right, and text should be drawn to the left.
| FLOAT DWRITE_GLYPH_RUN::fontEmSize |
Logical size of the font in DIPs, not points (equals 1/96 inch).
| _Notnull_ IDWriteFontFace* DWRITE_GLYPH_RUN::fontFace |
The physical font face to draw with.
| UINT32 DWRITE_GLYPH_RUN::glyphCount |
The number of glyphs.
| BOOL DWRITE_GLYPH_RUN::isSideways |
If true, specifies that glyphs are rotated 90 degrees to the left and vertical metrics are used. Vertical writing is achieved by specifying isSideways = true and rotating the entire run 90 degrees to the right via a rotate transform.
