Documentation

pattern VERSION_STRING :: Text

A string literal containing the version of Pango available at compile-time.

pattern VERSION_MINOR :: Int32

The minor component of the version of Pango available at compile-time.

pattern VERSION_MICRO :: Int32

The micro component of the version of Pango available at compile-time.

pattern VERSION_MAJOR :: Int32

The major component of the version of Pango available at compile-time.

pattern SCALE :: Int32

The scale between dimensions used for Pango distances and device units.

The definition of device units is dependent on the output device; it will typically be pixels for a screen, and points for a printer. SCALE is currently 1024, but this may be changed in the future.

When setting font sizes, device units are always considered to be points (as in "12 point font"), rather than pixels.

pattern GLYPH_UNKNOWN_FLAG :: Word32

Flag used in PangoGlyph to turn a gunichar value of a valid Unicode character into an unknown-character glyph for that gunichar.

Such unknown-character glyphs may be rendered as a 'hex box'.

pattern GLYPH_INVALID_INPUT :: Word32

A PangoGlyph value for invalid input.

PangoLayout produces one such glyph per invalid input UTF-8 byte and such a glyph is rendered as a crossed box.

Note that this value is defined such that it has the GLYPH_UNKNOWN_FLAG set.

Since: 1.20

pattern GLYPH_EMPTY :: Word32

A PangoGlyph value that indicates a zero-width empty glpyh.

This is useful for example in shaper modules, to use as the glyph for various zero-width Unicode characters (those passing [funcisZeroWidth]).

pattern ATTR_INDEX_TO_TEXT_END :: Word32

Value for endIndex in PangoAttribute that indicates the end of the text.

Since: 1.24

pattern ATTR_INDEX_FROM_TEXT_BEGINNING :: Word32

Value for startIndex in PangoAttribute that indicates the beginning of the text.

Since: 1.24

pattern ANALYSIS_FLAG_NEED_HYPHEN :: Int32

Whether to add a hyphen at the end of the run during shaping.

Since: 1.44

pattern ANALYSIS_FLAG_IS_ELLIPSIS :: Int32

Whether this run holds ellipsized text.

Since: 1.36.7

pattern ANALYSIS_FLAG_CENTERED_BASELINE :: Int32

Whether the segment should be shifted to center around the baseline.

This is mainly used in vertical writing directions.

Since: 1.16
