PixelCoordinateOverlay

All Known Implementing Classes:

RemoveTransparentShuffleOverlay, SequenceOverlay, ShuffleOverlay, TableOverlay
```
public interface PixelCoordinateOverlay
```
Classes that implement this interface should be able to return pixels of a given BufferedImage or similar image representation in an order independent from the coordinate system of the pixels (to act as an overlay).

They are meant to be used by encoding algorithms (BuffImgEncoder), so arranging and en- / decoding pixels are separate procedures.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`available()`	Returns the number of remaining pixels (not yet returned by next())
`int`	`next()`	Returns the next pixel value as an int (representing ARGB as its bytes), meaning the next pixel determined by the Overlay.
`void`	`setPixel(int value)`	Sets the current pixel to the given value

- Method Detail
  - next
```
int next()
  throws java.util.NoSuchElementException
```
    Returns the next pixel value as an int (representing ARGB as its bytes), meaning the next pixel determined by the Overlay.
    
    Returns:
    
    int representing the next pixel by the Overlay.
    
    Throws:
    
    java.util.NoSuchElementException - if there is no next pixel
  - setPixel
```
void setPixel(int value)
       throws java.util.NoSuchElementException
```
    Sets the current pixel to the given value
    
    Parameters:
    
    value - the value to set the current pixel to
    
    Throws:
    
    java.util.NoSuchElementException - if setPixel() is called before the first call to next(). Or if setPixel() is called after the last call to next() produced a NoSuchElementException
  - available
```
int available()
```
    Returns the number of remaining pixels (not yet returned by next())
    
    Returns:
    
    number of remaining pixels
