20 Setting Up Transformation Matrices

20 Q3Matrix3x3_SetScale

You can use the Q3Matrix3x3_SetScale function to configure a 3-by-3 scaling transformation matrix.

TQ3Matrix3x3 *Q3Matrix3x3_SetScale (
TQ3Matrix3x3 *matrix3x3, 
float xScale, 
float yScale);
matrix3x3 A 3-by-3 matrix.
xScale The desired amount of scaling along the x coordinate axis.
yScale The desired amount of scaling along the y coordinate axis.

DESCRIPTION


The Q3Matrix3x3_SetScale function returns, as its function result and in the matrix3x3 parameter, a scaling matrix that scales an object by the amount xScale along the x coordinate axis and by the amount yScale along the y coordinate axis.
