Apologies for any ignorance, but I have never worked with jpeg images (let alone any types of images) in Java before.
Supposing I want to send a jpeg image from a web service to a client. Is there any way that I can reduce the jpeg file size by manipulating the colour profile of the image in some way?
I have already been able to reduce the image size by scaling it using a neat tool for BufferedImages called imgscalr. See here.
I would also like a jpeg that has less colours than a high quality jpeg image. For example, I would like to be able to use 8bit colour in my jpeg instead of say 16bit colour.
What exactly would I need to change if I have a BufferedImage from Java's 2D package?
