- TransfertRectIter

All Implemented Interfaces:

RectIter, WritableRectIter
```
public final class TransfertRectIter
extends Object
implements WritableRectIter
```
A writable iterator that read pixel values from an image, and write pixel values to a different image. All get methods read values from the source image specified at creation time. All set methods write values to the destination image specified at creation time, which may or may not be the same than the source image. This is different than the usual WritableRectIter contract, which read and write values in the same image. This TransfertRectIter is convenient for the implementation of some image operations.

public static WritableRectIter create(RectIter src,
                                      WritableRectIter dst)
```
    Creates a WritableRectIter for the specified source and destination iterator. The two iterators must iterate over a rectangle of the same size, otherwise a RasterFormatException may be thrown during the iteration.
    
    Parameters:
    
    src - The source iterator.
    
    dst - The destination iterator.
    
    Returns:
    
    An iterator that read sample from src and write sample to dst. If src == dst, then the destination iterator itself is returned.
