Construct image from Array of pixels

Question

Here's my problem:
I've managed to call the pixelgrabber method on an image, so i've got a 1d array of pixels. Now i want to use that array to create the image within the internal frame so that the image can be changed quickly when the contents of the array change. I was wondering whether using the paint method and mofiying it in some way is the way to go, or is there a much better way to do it?

Answer 1

i'm guessing that no one knows an answer?Bad guess. I know the answer.
The solution lays in the correct use of the following classes:
BufferedImage
WritableRaster
DataBuffer
SampleModel
ColorModel
It goes something like this:
1) Wrap a raw array (probably bytes or ints) in a DataBuffer.
2) Create a SampleModel that describes the layout of the raw data.
3) Now create a WritableRaster that wraps the DataBuffer and SampleModel
4) Create a ColorModel that describes how the raw data maps to the color of a pixel.
5) A BufferedImage can be created from the WritableRaster and the ColorModel.
Drawing operations on the BufferedImage's Graphics2D objects will be reflected in the raw data array. And modifications to the raw data array will be shown when the BufferedImage is drawn onto other Graphics.
