I will be starting a contract with a film production company soon, and will be writing code to process large images representing frames of movies (unknown file format at this time). I'd also like to build the interface in Java, and do the number crunching in Java too, if Java is powerful enough to handle it.
I'd like to know what the best ways are to accomplish this. Should I treat image data as arrays of bytes and use the old producer/consumer model to construct images, or is it best to use BufferedImages and Rasters? Should I use javax.ImageIO to load images, the Toolkit and MediaTracker, or implement my own loader that takes advantage of NIO?
Top priority tasks would include loading images quickly, writing images quickly, caching images and/or thumbnails for realtime animation, and applying filters and tweaking individual pixles of images. I'm very familiar with the Java2D API, but feel I don't know much about the more data centered aspects of image manipulation.
Is Java up to this task? Would it be best to write the heavy duty stuff in C++ and use the JNI to call it?
Where can I find a general discussion of the data-wise impact of image manipulation in Java? All of the Java2D stuff I find is about fancy ways to draw shapes; I can't find much on direct access, what a Register does, or otherwise how to deal with an image as data.
Thanks
