rotateFromVector method

Post-multiplies the matrix by a specified rotation transformation and returns the resulting matrix.

Scalable Vector Graphics: Coordinate Systems, Transformations and Units, Section 7.14.3Internet Explorer 9

 

Syntax


ISVGMatrix retVal = object.rotateFromVector(x, y);

Parameters

x [in]

Type: float

The x-coordinate of a vector (x,y) that determines the rotation angle. This coordinate cannot be zero.

y [in]

Type: float

The y-coordinate of a vector (x,y) that determines the rotation angle. This coordinate cannot be zero.

Standards information

Remarks

The rotation angle is determined by taking (+/-)arctan(y/x). The direction of the vector (x,y) determines whether the positive or negative angle value is used.

Post-multiplies means that other matrix operations are performed before this operation.
