Examples of java.awt.geom.AffineTransform.transform()

java.awt.geom.AffineTransform.transform()
Transforms the specified ptSrc and stores the result in ptDst. If ptDst is null, a new {@link Point2D}object is allocated and then the result of the transformation is stored in this object. In either case, ptDst, which contains the transformed point, is returned for convenience. If ptSrc and ptDst are the same object, the input point is correctly overwritten with the transformed point. @param ptSrc the specified Point2D to be transformed @param ptDst the specified Point2D that stores theresult of transforming ptSrc @return the ptDst after transformingptSrc and stroring the result in ptDst. @since 1.2
