Hello all, I am having difficulty creating a TIFF Image file from abinary raw data.I tried to used ImageIO or ImageJ but with no luck. My implementationis as follows:import javax.imageio.*;import javax.imageio.stream.*;import ij.ImagePlus;import ij.io.Opener;import java.io.*;import java.awt.Image;protected Image load(byte[] data) { ByteArrayInputStream is = new ByteArrayInputStream(data); Image image = null; try { // Using ImageIO //image = ImageIO.read(is); //ImageWaiter.wait(image); // Using ImageJ ImagePlus imagej = new Opener().openTiff(is, "cmfdata"); if (imagej != null) { image = imagej.getImage(); } } catch (Throwable e) { System.out.println("Error occurs"); image = null; } return image;}If you can spot something wrong with above code, please kindly informme. Any thoughtful ideas are greatly appreciated.

I recommend posting SSCCE code.

<dws>Was that 'thoughtful' enough?</dws>

Hello,Thank you for your response. I don't know how you compiled the loadmethod. I used Eclipse and there is no compilation error. Theproblem is that this method doesn't work as expected, i.e. image isalways equal to null. I am looking for a way to create a TIFF imagefrom raw binary data...Thanks,Helen

Your question is not clear to me.
Several interpretations that I can come up with:
1. You wish to construct a java.awt.Image from a TIFF file, or
from an array of bytes which represent the contents of a valid
TIFF file.
Please run the following small program, if it does not output
something like tif, tiff, TIF, or TIFF, you probably cannot
use java.imageio.ImageIO.read.
I am not familiar with ImageJ.
You might be able to use Java Advanced Imaging.
A (naive) example follows at the end of this post.
public class PrintReaders
{
public static void main(String[] args)
{
for (String s : ImageIO.getReaderFormatNames())
System.out.println(s);
}
}
2. You have an array of bytes which represent some image data,
and you wish to construct a TIFF file from this (raw) data.
First you will need to determine exactly what kind of data you
have, and whether the TIF format is able to accomodate this
type of data. See the TIFF specification at:
<http://partners.adobe.com/public/developer/tiff/index.html>
You will then need to write the appropriate TIFF metadata and data
to a file. You can do this manually or perhaps there is some
Java language API to do this.
3. You have some (raw) data from a device, such as a camera or
scanner you wish to convert to a TIFF file.
There is probably some software associated with the device that
will convert the raw data to a TIFF file. Else, see:
<http://en.wikipedia.org/wiki/RAW_image_format>
for some introductory discussion on raw image data, if you
are not already familiar with it.

Not at all. In fact, I'm glad you asked. I was tempted to
post it in my reply, but the changes were so trivial I thought
best not at the time.

You'll have to forgive my failure to wrap those calls
to Swing methods in a Runnable, (shrugs) or perhaps
not. In any case, I am confident you are capable of
doing that yourself, and I wanted to post the code
*exactly* as I'd seen it work.
Oh, and if I was going to take it beyond 'absolutely trivial'
changes, I would probably swap that first input dialog for
a JFileChooser.

Cool. Thanks to 'aastha' for the original code, and you
for the alterations and link. That was actually the first
time I'd played with JAI, your post 'inspired me'. :-)

It stilldoesn't work for my binary raw data array though. I got this bytearray from a X9 file, which is in ASCII format. The image data ofthis x9 file consists of 8 bytes of Image header and the rest areRaster data.

How could a TIFF image be in ASCII format?

To be more precise, theTIFF image data presented in the X9 file is binary stream. I amtrying to figure out how to create a TIFF image from the byte arrayread from the x9 file. Hope this will make more sense.

Your code works perfectly when I only used the Raster image data partto create a TIFF file.Thanks to everyone's participation!~helen
