IXRRotateTransform::SetAngle (Windows Embedded CE 6.0)
1/6/2010
This method sets the angle, in degrees, of clockwise rotation.
Syntax
virtual HRESULT STDMETHODCALLTYPE SetAngle(
float Angle
) = 0;
Parameters
- Angle
[in] A value that indicates the angle, in degrees, of clockwise rotation.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
When you use an IXRRotateTransform object, the transformation rotates the coordinate system for a particular object around the point (0,0). The object itself is not necessarily rotated around its center. For example, if an object is positioned 200 units from the x-axis, a rotation of 30 degrees will swing the object 30 degrees along a circle that has a radius of 200 centered at the origin. To rotate an object in place, pass the x-coordinate and y-coordinate of the center of the object in IXRRotateTransform::SetCenterX and IXRRotateTransform::SetCenterY.
The local origin point for an object can be offset on an IXRCanvas container object by setting the Canvas.Left and Canvas.Top attached properties through IXRDependencyObject::SetAttachedProperty. However, this does not count as a transform. The object keeps its own local origin point for transformation purposes.
