Virtual Method

PangoFontget_glyph_extents

Declaration [src]

void
get_glyph_extents (
  PangoFont* font,
  PangoGlyph glyph,
  PangoRectangle* ink_rect,
  PangoRectangle* logical_rect
)

Description [src]

Gets the logical and ink extents of a glyph within a font.

The coordinate system for each rectangle has its origin at the base line and horizontal origin of the character with increasing coordinates extending to the right and down. The macros PANGO_ASCENT(), PANGO_DESCENT(), PANGO_LBEARING(), and PANGO_RBEARING() can be used to convert from the extents rectangle to more traditional font metrics. The units of the rectangles are in 1/PANGO_SCALE of a device unit.

If font is NULL, this function gracefully sets some sane values in the output variables and returns.
