#[repr(transparent)]pub struct Rectangle { /* private fields */ }
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§
source§impl Rectangle
impl Rectangle
pub fn as_ptr(&self) -> *mut GdkRectangle
sourcepub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const GdkRectangle) -> &'a Self
pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const GdkRectangle) -> &'a Self
Borrows the underlying C value.
sourcepub unsafe fn from_glib_ptr_borrow_mut<'a>(
ptr: *mut GdkRectangle
) -> &'a mut Self
pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut GdkRectangle ) -> &'a mut Self
Borrows the underlying C value mutably.
source§impl Rectangle
impl Rectangle
sourcepub fn contains_point(&self, x: i32, y: i32) -> bool
pub fn contains_point(&self, x: i32, y: i32) -> bool
sourcepub fn intersect(&self, src2: &Rectangle) -> Option<Rectangle>
pub fn intersect(&self, src2: &Rectangle) -> Option<Rectangle>
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
Returns
true
if the rectangles intersect.
dest
return location for the intersection of @self and @src2
sourcepub fn union(&self, src2: &Rectangle) -> Rectangle
pub fn union(&self, src2: &Rectangle) -> Rectangle
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
Returns
dest
return location for the union of @self and @src2
