AcquireBiasTransform

The AcquireBiasTransform method returns a reference to the bias transform associated with this canvas.

ODTransform AcquireBiasTransform ();

return value

A reference to the bias transform associated with this canvas, or kODNULL if no bias transform has previously been assigned to this canvas.

DISCUSSION

If you call methods that modify the returned transform, you must then call this canvas's SetBiasTransform method to set its bias transform to the modified transform.

This method increments the reference count of the returned transform. When you have finished using that transform, you should call its Release method.
