L_Matrix_Set

#include "LtPrimitives.h"

L_LTKRN_API L_VOID L_Matrix_Set(matrix, m11, m12, m21, m22, offsetX, offsetY)

L_MATRIX* matrix;	pointer to the structure to set
L_DOUBLE m11;	The m11 value
L_DOUBLE m12;	The m12 value
L_DOUBLE m21;	The m21 value
L_DOUBLE m22;	The m22 value
L_DOUBLE offsetX;	The offsetX value
L_DOUBLE offsetY;	The offsetY value

Sets the values of the specified L_MATRIX structure.

Parameter	Description
matrix	Pointer to the L_MATRIX to set.
m11	The value of the first row and first column.
m12	The value of the first row and second column.
m21	The value of the second row and first column.
m22	The value of the second row and second column.
offsetX	The value of the third row and first column. The offsetX member is so named because it specifies the amount to translate the coordinate space along the x-axis.
offsetY	The value of the third row and second column. The offsetY member is so named because it specifies the amount to translate the coordinate space along the y-axis.

None.

Comments

The L_MATRIX is stored using row-major order and has the following structure:

The members in the last row, offsetX and offsetY, represent translation values.

In functions and structure memebers, the transformation matrix is usually specified as a vector with only six members, as follows:

(m11, m12, m21, m22, offsetX, offsetY)
