Pixel array into Image

[D i s h a n]

Hi,
Is there anyway to convert Pixel array (from PixelGrabber) into gif/jpg
image (Black and White) programmatically ?
Thanks

My understanding of PixelGrabber is that the PixelGrabber object is
initialized with a sub-region of an image. Why not just crop from the
original image?

BufferedImage image = new BufferedImage(width, height,
source.getType(), source.getColorModel);
image.getGraphics().drawImage(source, -sourceX, -sourceY, null);

Other than that, there are ways to convert a byte/int array to an
image, but its better if you don't have to mess with those details.

If you must, look up MemoryImageSource.

Actually BufferedImage has simple methods to convert an int[] to a
BufferedImage. But that aside, what are you really trying to do with
the PixelGrabber? I can't think of a single good reason to ever use one.

I can think of a few, but all of them involve saving in an otherwise
unsupported file/compresson format.

Hi, Reason is this.. I dont have original content file(gif) rather than
just pixel byte array. Thats why I want to convert that byte array into
gif image backword.
Thanks in advance
