| #define PANGO_GLYPH_EMPTY ((PangoGlyph)0x0FFFFFFF) |
PANGO_GLYPH_EMPTY:
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 [func@is_zero_width]). PANGO_GLYPH_INVALID_INPUT:
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 PANGO_GLYPH_UNKNOWN_FLAG set.
Since: 1.20 PANGO_GLYPH_UNKNOWN_FLAG:
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'. PANGO_GET_UNKNOWN_GLYPH: @wc: a Unicode character
The way this unknown glyphs are rendered is backend specific. For example, a box with the hexadecimal Unicode code-point of the character written in it is what is done in the most common backends.
Returns: a PangoGlyph value that means no glyph was found for @wc.

PANGO_SCALE_XX_SMALL:
The scale factor for three shrinking steps (1 / (1.2 * 1.2 * 1.2)). PANGO_SCALE_X_SMALL:
The scale factor for two shrinking steps (1 / (1.2 * 1.2)). PANGO_SCALE_SMALL:
The scale factor for one shrinking step (1 / 1.2). PANGO_SCALE_MEDIUM:
The scale factor for normal size (1.0). PANGO_SCALE_LARGE:
The scale factor for one magnification step (1.2). PANGO_SCALE_X_LARGE:
The scale factor for two magnification steps (1.2 * 1.2). PANGO_SCALE_XX_LARGE:
The scale factor for three magnification steps (1.2 * 1.2 * 1.2).

PangoFontMetrics:
A PangoFontMetrics structure holds the overall metric information for a font.
The information in a PangoFontMetrics structure may be restricted to a script. The fields of this structure are private to implementations of a font backend. See the documentation of the corresponding getters for documentation of their meaning.
For an overview of the most important metrics, see:
