Public Member Functions
bool	isValid () const noexcept
	Checks whether the geometry is usable.

Public Attributes
SkRect	viewport
	Virtual coordinate space of the surface (source rect).
SkRect	dst
	Destination rect the viewport is mapped to within the backing image.
CZTransform	transform { CZTransform::Normal }
	Transform applied when mapping the viewport onto the destination.

Detailed Description

Describes the coordinate mapping of an RSurface.

Defines how the surface's virtual viewport is mapped onto its destination rect within the backing image, along with the transform applied during that mapping.

Member Function Documentation

isValid()

bool isValid ( ) const

inlinenoexcept

Checks whether the geometry is usable.

Returns

true if both viewport and dst are sorted, non-empty and finite.

viewport

SkRect viewport

Virtual coordinate space of the surface (source rect).

dst

SkRect dst

Destination rect the viewport is mapped to within the backing image.

transform

CZTransform transform { CZTransform::Normal }
