ImageIO.createImageInputStream Keeps Returning null

Question

Hey all, Whenever I try to get an ImageInputStream object using ImageIO.createImageInputStream it simply returns null with no exceptio

Answer 1

Why are you doing all that?? you can simply do this:

image = ImageIO.read(source);

No Iterators, ImageInputStreams... no nothing !

EDIT: Since you insist, your code is not working because you're sending a File to ImageIO.getImageReaders() instead of a ImageInputStream. SO your code should look something like that:

ImageInputStream iis = ImageIO.createImageInputStream(source);
Iterator readers = ImageIO.getImageReaders(iis);
ImageReader reader = (ImageReader) readers.next();

reader.setInput(iis, false);
image = reader.read(imageIndex);
