Struct gdk4::Rectangle[][src]

#[repr(transparent)]
pub struct Rectangle(_);
Expand description

A Rectangle data type for representing rectangles.

Rectangle is identical to cairo_rectangle_t. Together with Cairo’s cairo::Region data type, these are the central types for representing sets of pixels.

The intersection of two rectangles can be computed with intersect(); to find the union of two rectangles use union().

The cairo::Region 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.

Implementations

Returns true if @self contains the point described by @x and @y.

x

X coordinate

y

Y coordinate

Returns

true if @self contains the point

Calculates the intersection of two rectangles.

It is allowed for @dest to be the same as either @self or @src2. If the rectangles do not intersect, @dest’s width and height is set to 0 and its x and y values are undefined. If you are only interested in whether the rectangles intersect, but not in the intersecting area itself, pass None for @dest.

src2

a Rectangle

Returns

true if the rectangles intersect.

dest

return location for the intersection of @self and @src2

Calculates the union of two rectangles.

The union of rectangles @self and @src2 is the smallest rectangle which includes both @self and @src2 within it. It is allowed for @dest to be the same as either @self or @src2.

Note that this function does not ignore ‘empty’ rectangles (ie. with zero width or height).

src2

a Rectangle

Returns
dest

return location for the union of @self and @src2
