What are the advantages of converting a buffered image into an array of integers?I assume that i can manipulate the array and cross process the picture .Is that so?

1How does "cross process the picture" differ from "process the picture"? What does 'cross' mean here?Andrew Thompson– Andrew Thompson2012-10-13 10:16:15 +00:00Commented Oct 13, 2012 at 10:16

I think you are referring to getRgb() method of BufferedImage class.
Supposing you want to modify the whole image or a big portion of it, retrieving the pixel array, and perform operations on it could be considerely faster than accessing each single pixel through method calls such as setRgb().

SwingX introduces the AbstractFilter class for BufferedImage. Here is an example:
For simple editing use one of this examples:

Having a BufferedImage into memory as an array of int values could help you apply filters on the image by processing the int values into memory and then setting the result back to another BufferedImage.
