                         int[] pixels)
```
Writes a rectangular area of pixels in the destination BufferedImage. Calling this method on an image of type different from BufferedImage.TYPE_INT_ARGB and BufferedImage.TYPE_INT_RGB will unmanage the image.

Parameters:

img - the destination image

x - the x location at which to start storing pixels

y - the y location at which to start storing pixels

w - the width of the rectangle of pixels to store

h - the height of the rectangle of pixels to store

pixels - an array of pixels, stored as integers

Throws:

IllegalArgumentException - is pixels is non-null and of length < w*h
