Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipSrcPoints

ITcVnContainer*

Source points (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL or ContainerType_Vector_TcVnPoint2_LREAL)

ipDestPoints

ITcVnContainer*&

Returns the transformed points (same type ID as ipSrcPoints; Non-zero interface pointers are reused.)

aTransformationMatrix

TcVnMatrix3x3_LREAL&

Perspective transformation matrix
