)

Parameters

sourceType

The source coordinate type.

destinationType

The destination coordinate type.

rect

The rectangle to be converted.

Return Value

Use this method to convert a rectangle value from control to image coordinates or back. This method will simply multiply the rectangle value by the transformation matrix (Transform) when converting from image to control coordinates and by the inverse of this matrix when converting from control to image coordinate.

If sourceType has the same value as destinationType, then this method will return a value equal to rect.
