Convert a tiff into a buffered image (Java)

Question

I need to convert a tiff file into a BufferedImage. I wrote the following code:

String filepath = "C:\\tiffFolder\\";
String filename = "myTiffImage.tif";
File myFile = new File (filepath + filename); 
BufferedImage img = ImageIO.read(myFile);

I know for sure myFile is correctly instantiated: the problem is that after the fourth line of code img is still null.

What am I doing wrong? Thanks so much!

Edit

Solved, I used the following code:

FileSeekableStream stream = new FileSeekableStream(filepath + filename);
TIFFDecodeParam decodeParam = new TIFFDecodeParam();
decodeParam.setDecodePaletteAsShorts(true);
ParameterBlock params = new ParameterBlock();
params.add(stream);
RenderedOp image1 = JAI.create("tiff", params);
BufferedImage img = image1.getAsBufferedImage();

@DanieleMilani Check what does the following line print out : `System.out.println(Arrays.toString(ImageIO.getReaderFileSuffixes()));` On my machine it is `[bmp, jpg, jpeg, wbmp, png, gif]`. No `tif`. — johnchen902, Jul 08 '13 at 10:16
Try use another image (jpg), I'm not sure if ImageBuffer support tif format. — Sk1X1, Jul 08 '13 at 10:16
@johnchen902 it prints [bmp, jpg, wbmp, jpeg, png, gif]... i think that this is the problem! Is it possible to add tif and tiff to the ImageIo supported suffixes? — Daniele Milani, Jul 08 '13 at 10:18
@Sk1X1 I need to convert tif into BufferReader: is it possible? — Daniele Milani, Jul 08 '13 at 10:19
@DanieleMilani: yes, but not with ImageIO. Take a look at JAI (details in my answer). — Burkhard, Jul 08 '13 at 10:20

You are trying to read a file format that is not supported by ImageIO.

As johnchen902 pointed out, the ImageIO.getReaderFileSuffixes() returns a list of suffixes that are supported. tiff is not in that list. That's why you cannot read it that way. Some external libaries might help you. For instance: The Java Advanced Imaging API supports TIFF. Details here.
