|
| TEXT_IS_PERSISTENT |
When set, the text string pointer used to create the text run is guaranteed to be available during the lifetime of the text run.
|
| TEXT_IS_ASCII |
When set, the text is known to be all-ASCII (< 128).
|
| TEXT_IS_RTL |
When set, the text is RTL.
|
| TEXT_ENABLE_SPACING |
When set, spacing is enabled and the textrun needs to call GetSpacing on the spacing provider.
|
| TEXT_ENABLE_HYPHEN_BREAKS |
When set, GetHyphenationBreaks may return true for some character positions, otherwise it will always return false for all characters.
|
| TEXT_IS_8BIT |
When set, the text has no characters above 255 and it is stored in the textrun in 8-bit format.
|
| TEXT_NEED_BOUNDING_BOX |
When set, the RunMetrics::mBoundingBox field will be initialized properly based on glyph extents, in particular, glyph extents that overflow the standard font-box (the box defined by the ascent, descent and advance width of the glyph).
When not set, it may just be the standard font-box even if glyphs overflow.
|
| TEXT_DISABLE_OPTIONAL_LIGATURES |
When set, optional ligatures are disabled.
Ligatures that are required for legible text should still be enabled.
|
| TEXT_OPTIMIZE_SPEED |
When set, the textrun should favour speed of construction over quality.
This may involve disabling ligatures and/or kerning or other effects.
