Hi all,<br><br>process with a large amount of data like images is always a problem in Java. But you don't need to use JAI. You can process with any image by divide it in smaller rasters. That's why you have xoff and yoff arguments in ReadRaster and WriteRaster Method. You fix width and height of the raster you read and add them of offsets of next raster you read.<br>
