Reading byte array

Java 2D
#1

Hi,

I’m trying to load a tiff image straight into a byte array, but seem to be struggling. At the moment I’m trying JAI to do it:

File imgFile = new ("c:\\image.tif");

ImageInputStream stream = ImageIO.createImageInputStream;
Iterator iter = ImageIO.getImageReaders(stream);
if (iter.hasNext())  
                                  {
                                    ImageReader reader = (ImageReader)iter.next();

reader.setInput(stream, true, true);
                                    int w = reader.getWidth(0);
                                    int h = reader.getHeight(0);

byte[] b = new byte[w*h*3];
stream.read(b);
}

The trouble is, this creates an image which is 90% black with a load of colour at the end. So I’m presuming that it’s not been decoded and decompressed.

I guess what I’m really what I’m looking for is:

reader.read(b);

but this doesn’t seem to be available. It seems like it should be a fairly common thing to want to do, so I was wondering if it was possible in JAI or any other APIs. I’ve spent quite a few days trawling through the javadocs and so far not managed to come up with nothing. Any help would be great!

I don’t think ImageIO supports tif. Does it?

#3

IIRC it does, just not all of its features (uncompressed only?).

#4

yeah, it loads the file fine into a BufferedImage. It has a TiffImageDecoder (or something like that) class which does the work i think…
