Name

PEXInvertMatrix2D

Synopsis

int PEXInvertMatrix2D(PEXMatrix3x3 transform, PEXMatrix3x3 transform_return)

Arguments

transformThe transformation matrix to invert

transform_return
The inverse transformation

Returns

Zero if successful; non-zero if unsuccessful. 

Description

This function computes the inverse of a 2D transformation matrix. 

An unsuccessful status is returned if the matrix is non-invertible. 

The two arguments may be the same variable, in which case the inversion is performed in-place, overwriting the original transform. 

Errors

None
