Java : read an image inside a binary file (or maybe more generally, from a stream)

Question

I am making a java program that reads a binary file, which contains multiple images (in PNG format), and some binary data.

How can i load the images (specifically, as java.awt.Image 's)? So far the only way i have found to load an image is via functions that just take a file. How can i do it from, say, an InputStream?

Answer 1

The ImageIO#read(InputStream) method does return a java.awt.image.BufferedImage (which extends from java.awt.Image ).
