int ViewSetRotate(int vw, int degrees);

Rotates a View by the specified number of degrees.

Return Value

Returns zero if function fails.

Parameters

vw

View handle returned from ViewAdd().

degrees

Number of degrees by which to rotate the image.  Positive values rotate clockwise; negative values rotate counter-clockwise.

Remarks

The ViewSetRotate() function rotates the image contained in the view.  This function will rotate the image based on its original size and will not scale the image.  If ViewSetSize() is called prior to a call to ViewSetRotate() then ViewSetRotate() will scale the image back to its original size.
