Make a BufferedImage use less RAM?

Question

I have java program that reads a jpegfile from the harddrive and uses it as the background image for various other things. The image itself is stored in a BufferImage

Answer 1

You could copy the pixels of the image to another buffer and see if that occupies less memory then the BufferedImage object. Probably something like this:

BufferedImage background = new BufferedImage(
   width, 
   height, 
   BufferedImage.TYPE_INT_RGB
);

int[] pixels = background.getRaster().getPixels(
    0, 
    0, 
    imageBuffer.getWidth(), 
    imageBuffer.getHeight(), 
    (int[]) null
);
