TProjectiveTransformation = class(T3x3Transformation)

Description ​

TProjectiveTransformation performs projective (perspective) spatial mapping by mapping a source rectangle (SrcRect) onto an arbitrary 4-corner convex destination quadrilateral defined by vertex properties (X0..X3, Y0..Y3).

Note

The destination quadrilateral must be convex, otherwise the result is undefined.
