[java] Question about Bitmap API[Solved]
Author
I want to read BASIC(Black or White) color information from a fairly large(800x800 pixels) saved bitmap, in the background of my application. So I was wondering, what API's/Methods I should be using to do this... Is this a slow process?
Could this be done with JOGL?
If so would the BufferedImage class be sufficient?
Any idea's would be appreciated, the java API index honestly is giving me a headache.

Thanks. I'll be reading :).
Will Java2D allow me to access information about an image without having it being displayed?

Sure. Load your images into a BufferedImage object and you'll have access to them without having to render the image to the screen (which would require a call to Graphics2D.drawImage(myBufferedImage, ...))
You should look into the BufferedImage api for sure. In particular check out the BufferedImage.getRaster() method, it returns the image's pixel data in a modifiable array, which is probably the most efficient way of doing pixel operations on an image, besides using openGL/directX of course.
