Indicates whether the specified L_MATRIX is an identity matrix.
#include "LtPrimitives.h"
L_LTKRN_API L_BOOL L_Matrix_IsIdentity(matrix)
Pointer to the L_MATRIX to test.
Value | Meaning |
---|---|
TRUE | The L_MATRIX is an identity matrix. |
FALSE | The L_MATRIX is not an identity matrix. |
An identity matrix has a value of 1 in coefficients [1,1],[2,2],[3,3] and a value of 0 in the rest of the coefficients. This correlates to setting m11 and m22 to 1 and m12, m21, offsetX, and offsetY to 0.
In an affine matrix, coefficients [3,1],[3,2],[3.3] are implied to always have the values 0,0,1 respectively.
Win32, x64, Linux.
