![]() |
It is frequently used to represent the logical or ink extents of a single glyph or section of text. The coordinate system for each rectangle has its origin at the base line and the horizontal origin of the character with increasing coordinates extending to the right and down. get_ascent(), get_descent(), get_lbearing(), and get_rbearing() can be used to convert from the extents rectangle to more traditional font metrics. The units of rectangles usually are in 1/PangoSCALE of a device unit.

int Pango::Rectangle::get_ascent | ( | ) | const [inline] |
Extracts the ascent from a Pango::Rectangle representing glyph extents.
The ascent is the distance from the baseline to the highest point of the character. This is positive if the glyph ascends above the baseline.
int Pango::Rectangle::get_descent | ( | ) | const [inline] |
Extracts the descent from a Pango::Rectangle representing glyph extents.
The descent is the distance from the baseline to the lowest point of the character. This is positive if the glyph descends below the baseline.
int Pango::Rectangle::get_height | ( | ) | const [inline] |
Gets the height of the rectangle.
int Pango::Rectangle::get_lbearing | ( | ) | const [inline] |
Extracts the left bearing from a Pango::Rectangle representing glyph extents.
The left bearing is the distance from the horizontal origin to the farthest left point of the character. This is positive for characters drawn completely to the right of the glyph origin.
int Pango::Rectangle::get_rbearing | ( | ) | const [inline] |
Extracts the right bearing from a Pango::Rectangle representing glyph extents.
The right bearing is the distance from the horizontal origin to the farthest right point of the character. This is positive except for characters drawn completely to the left of the horizontal origin.
