GDK provides the #GdkPoint and #GdkRectangle data types for representing pixels
|
|
and sets of pixels on the screen. Together with Cairo's #cairo_region_t data
|
|
type, they make up the central types for representing graphical data.

#GdkPoint is a simple structure containing an x and y coordinate of a point.

#GdkRectangle is a structure holding the position and size of a rectangle.
|
|
The intersection of two rectangles can be computed with
|
|
gdk_rectangle_intersect(). To find the union of two rectangles use
|
|
gdk_rectangle_union().
