List of deltaTransform() Examples

Examples of deltaTransform()

ae.java.awt.geom.AffineTransform.deltaTransform()
Transforms the relative distance vector specified by ptSrc and stores the result in ptDst. A relative distance vector is transformed without applying the translation components of the affine transformation matrix using the following equations:
```
 [  x' ]   [  m00  m01 (m02) ] [  x  ]   [ m00x + m01y ] [  y' ] = [  m10  m11 (m12) ] [  y  ] = [ m10x + m11y ] [ (1) ]   [  (0)  (0) ( 1 ) ] [ (1) ]   [     (1)     ] 
```
If ptDst is null, a new Point2D object is allocated and then the result of the transform 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 distance vector to be delta transformed @param ptDst the resulting transformed distance vector @return ptDst, which contains the result of thetransformation. @since 1.2
