I am working on an applet which will apply various transforms to jpgs. I have followed the Tutorial at http://www.developer.com/java/other/article.php/3403921 which is great, and I have a working sample. (it uses a PixelGrabber and MemoryImageSource) However, the images I need to work on are 1.5Mb jpg files. When I try to use my working code on one of them, I get an out of memory error. I then saved my jpg as a bitmap, and realised that it expands to about 40Mb, which explains the problem.)That is a fair amount of memory for an applet)
Now, I understand that I could get my users to increase the amount of memory on the virtual machine, but they arn't clever enough to do that.
I was hoping that there would be some way of taking a smaller chunck of the pixels each time, doing my transform, and putting that data into an image peice at a time so that the whole file is never uncompressed at the same time. Does anyone know if this is possible, and if so how?
thanks
