class Gdk::Rectangle

Overview

A GdkRectangle data type for representing rectangles.

GdkRectangle is identical to cairo_rectangle_t. Together with Cairo’s cairo_region_t data type, these are the central types for representing sets of pixels.

The intersection of two rectangles can be computed with Gdk::Rectangle#intersect; to find the union of two rectangles use Gdk::Rectangle#union.

The cairo_region_t type provided by Cairo is usually used for managing non-rectangular clipping of graphical operations.

The Graphene library has a number of other data types for regions and volumes in 2D and 3D.

Defined in:

lib/gi-crystal/src/auto/gdk-4.0/rectangle.cr
