ID2D1Transform interface (d2d1effectauthor.h)

  • Article

Represents the base interface for all of the transforms implemented by the transform author.

Inheritance

The ID2D1Transform interface inherits from ID2D1TransformNode. ID2D1Transform also has these types of members:

Methods

The ID2D1Transform interface has these methods.

 
ID2D1Transform::MapInputRectsToOutputRect

Performs the inverse mapping to MapOutputRectToInputRects.
ID2D1Transform::MapInvalidRect

Sets the input rectangles for this rendering pass into the transform.
ID2D1Transform::MapOutputRectToInputRects

Allows a transform to state how it would map a rectangle requested on its output to a set of sample rectangles on its input.

Remarks

Transforms are aggregated by effect authors. This interface provides a common interface for implementing the Shantzis rectangle calculations which is the basis for all the transform processing in Direct2D imaging extensions. These calculations are described in the paper A model for efficient and flexible image computing.
