Overview

A Gdk::Rectangle data type for representing rectangles.

Gdk::Rectangle 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

Constructors

• .new(pointer : Pointer(Void), transfer : GICrystal::Transfer)
