Matrix2x4::SetParlToRect

Matrix2x4& SetParlToRect(const T* parl, T x1, T y1, T x2, T y2);

Description

SetParlToRect transforms a parallelogram to a rectangle.

The parallelograms are defined by the matrices which represent the edge coordinates of the parallelogram. The 3 corners of the parallelogram are identified by a float array Float[6] mapped to x1, y1, x2, y2, x3, y3 and the fourth point is calculated internally.

Parameters

Parameters	Description
const T* parl	Pointer to float array representing the coordinates of the parallelogram.
T x1	The x coordinate value of the bottom left corner of the rectangle.
T y1	The y coordinate value of a bottom left corner of the rectangle.
T x2	The x coordinate value of top right corner point of the rectangle.
T y2	The y coordinate value of top right corner point of the rectangle.

Return Value

Matrix2x4 representing the transformed rectangle.
