Points and Rectangles Simple graphical data types 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(). #cairo_region_t is usually used for managing clipping of graphical operations. Defines the x and y coordinates of a point. @x: the x coordinate of the point. @y: the y coordinate of the point. Defines the position and size of a rectangle. It is identical to #cairo_rectangle_int_t. @src1: @src2: @dest: @Returns: @src1: @src2: @dest:
