Java Convert an Image to a Matrix

Hi all :)
I'm just wondering if there is some sort of method which allows me to create a matrix (or array of pixels) of a .tif image?
Thanks,
Alex.

Umm I've just tried that and it doesn't work for my .tif file.
I just need it to just print like that matrix or array of the image in the non-graphical form, so then I could read the values and change them.
Thanks :)

  • How can I convert an image created in Photoshop into a format that Java's ImageIO library will take?

    Hi all,
    I've been trying to write an image resize tool to use the Lancoz resample algorithm to resize images to a high standard in Java.  The library with the algorithm/filter in it is mortennobel's image scaling library and it takes a buffered image as an input and returns the resized image as desired.  However the trouble I’m having is that the ImageIO library in Java, a standard library, which converts images given to its read method to buffered images doesn't accept certain images created in Photoshop and so it throws an exception.  My library needs to be fully automated to process possible thousands of images at a time and so manually converting them by resaving them as JPEG's is really feasibly.  Is there some way I can convert these images from Adobes Exif format to standard JFIF format?  I've tried simple inserting the APP0 marker from a JFIF image in-between the SOI and APP1 marker but the ImageIO library still failed.
    The above image is a screenshot of the binary in hex of one of the images that cause an Invalid Format exception when passed to ImageIO.
    Any help you could offer me with this would be much appreciated.
    Kind regards and thank you,

    NB: I previously posted this post in Developers but was told to post it in a Photoshop forum so apologies if this is the incorrect formum

    The image scaling library does have a BiCubicFilter in it so I'll experiment around with them and see what happens.  As for the imageIO library I think it accepts Exif image types, but still for some reason it just doesn't like Adobe Photoshop types.  Maybe its the colour map it doesn't like I just can't seem to work out what's wrong which is slightly frustrating but looking round to see if I can find an answer

    You can do something like:
    image = new BufferedImage (width, height, BufferedImage.TYPE_INT_RGB);
    // create your image
    String path = "/path/image.jpg";
    Jimi.putImage(image, path);

  • How to convert an Image to a byte array?

    I want to make a screenshot and then convert the image to a byte of arrays so I can send it through a BufferedOutputStream.
    try
                   robot = new Robot();
                   screenshot = robot.createScreenCapture(new Rectangle(500,500));
                   imageFile = new File("image.png");
                   ImageInputStream iis = ImageIO.createImageInputStream(screenshot);
                   byte[] data = new byte[1024];
                   byte[] tmp = new byte[0];
                   byte[] myArrayImage = new byte[0];
                   int len = 0;
                   int total = 0;
                   while((len = iis.read(data)) != -1 ) // LINE 52 --- EXCEPTION CATCHED HERE
                        total += len;
                        tmp = myArrayImage;
                        myArrayImage = new byte[total];
                        System.arraycopy(tmp,0,myArrayImage,0,tmp.length);
                        System.arraycopy(data,0,myArrayImage,tmp.length,len);
                   ios.close();I get this exception while running:
    Exception in thread "Thread-0" java.lang.NullPointerException
    at Server.run(Server.java:52)
    at java.lang.Thread.run(Unknown Source)

    Fixed that. I got a new problem.
    When I connect to my simple server application that reads the image file, converts it to an array of bytes and sends it back, the file is created on the client side and it containts data, but I am not able to open the image. I have checked that the image that the server is sending is working. So where is the problem?
    The client application recieves the image as following:
    public void run()
            try
                socket = new Socket("127.0.0.1", 2000);
                BufferedOutputStream out_file = new BufferedOutputStream(new FileOutputStream("recieved_img.png"));
                BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                int inputLine;
                while((inputLine = in.read()) != -1)
                    char c = (char)inputLine;
                    System.out.println(c);
                    out_file.write(inputLine);
            catch(IOException err){ err.printStackTrace(); }
        }And the server sends the image like this;
    try
              socket = server.accept();
              in=new BufferedReader(new InputStreamReader(socket.getInputStream()));
              out = new BufferedOutputStream(socket.getOutputStream());
              out.write(25);
              while((inputLine = in.readLine()) != null)
                   System.out.println(myArrayImage.length);
              System.out.println(inputLine);
                        out.write(myArrayImage);     // Send the array of bytes
         }

  • Converting GIF images to JPG - display problems in browser

    I am currently writing a program that uses the ImageIO package (javax.imageio.*) to take GIF and PNG images and convert them to JPG images. The program seems to convert them correctly, especially for the PNG images, but the converted GIF images don't open in a browser. They open just fine in Windows Picture and Fax viewer, but when I try to open them in IE or Firefox, it only diplays the little red 'x'.
    Is anyone familiar enough with Images and the ImageIO package in Java that they may have some insight on why these converted GIF files won't display in a browser.

    Bonjour,
    In my [website|http://iweb.debutersurmac.com>, all the images are JPG files,
    By default iWeb '09 converts images to JPG (yes, it's true)...
    ...unless you use masked images*
    !http://i32.servimg.com/u/f32/09/02/44/99/masked10.jpg!
    Crop your images (with Preview) before you paste them in iWeb. Don't use mask, Unmask an image if it's masked. That's the trick!
    !http://i32.servimg.com/u/f32/09/02/44/99/unmask10.jpg!
    (* images with transparency areas (ex : some PNG and GIF), rotation and shapes in iWeb make also PNG files in your website.)

  • Convert colour images to grayscale images & get pixel data from them

    Is the code below correct to convert colour images to grayscale images in Java?
    public void convertToGrayscale (String sourceName,String destName) throws Exception {
    JPEGImageDecoder decoder=JPEGCodec.createJPEGDecoder(new FileInputStream(sourceName));
    JPEGImageEncoder encoder=JPEGCodec.createJPEGEncoder(new FileOutputStream(destName));
    BufferedImage sourceImg=decoder.decodeAsBufferedImage();
    BufferedImageOp op =new ColorConvertOp(
              ColorSpace.getInstance(ColorSpace.CS_GRAY),null);
         BufferedImage destImg = op.filter(sourceImg,null);
    encoder.encode(destImg);
    decoder = null;
    encoder = null;
    When I get grayscale images from the code below, I would like to access the pixels of those images. So I tried to do:
    byte[] dd=((DataBufferByte)mImage.getRaster().getDataBuffer()).getData();
    BUT the data result array is not 0-255. Could anyone suggest how to obtain pixel data from grayscale images?
    In case that my code shown is not correct or suitable, please give your advice. What I would like to do are in the steps as follows:
    1 change 100*70 jpeg-images to 100*70 grayscale images.
    2 create two dimensional array of pixel data (example [100][70]) from converted images. The number in the array should be between 0-255, right??? And 0 refers to black colour and 255 refers to white colour???
    I am confused about grayscale images. Please help.
    Thank you so much

    I am not sure i understand what is the problem exactly.
    Structure of DataBuffer is described by SampleModel used by same Raster
    object. E.g. it might be 1 byte per xipex or 4 bytes per pixel.
    In your example convertToGrayscale saves images to file as JPEG and
    it seems you later read it back. It is possible what image you read back
    is not greyscale but ARGB and data buffer has different format.
    Technically, if you just need level of grey you may simply
    call getRGB on your output image. Grey is uniform mix of R, G and B.
    Also, instead of ColorConverOp you may dimply create output image of
    grayscale type and draw your color input image with drawImage().
    If none of these helps please try to provide more details.

  • Converting JPEG image

    Hai
    In my application i had converted raw image of

    Now in jpeg format its
    size is 6.75kb
    width is 130

    now i have to convert it previous size raw format
    code i required
    please if any body know anything on this tell me its very urgent
    I am new to java advanced imagaing api .

    It might not be wise to store CBEFF format into card, since it has over head space required. However convert it at Host vice versa is perfect fine.

  • Converting an Image object to a BufferedImage object?

    I have a BufferedImage object, bi, which I want to resize, hence:
    Image image = bi.getScaledInstance(400, 300, Image.SCALE_DEFAULT);
    Next I want to encode the resized image to JPEG format. The problem is that inorder to use the JPEGImageEncoder.encode() method, I need to pass it a BufferedImage object. I have looked through the API and cant see a way of converting the Image object to a BufferedImage object.
    Can anyone shed some light on this problem?
    Any help will be much appreciated.

    I copied + pasted the code from:
    http://java.sun.com/docs/books/tutorial/2d/problems/ind
    x.html :-)
    So you propably could use :
    int width = 400;
    int height = 300;
    Image image = bi.getScaledInstance(width, height,
    Image.SCALE_DEFAULT);
    BufferedImage bi = new BufferedImage(width, height,
    BufferedImage.TYPE_INT_RGB);
    Graphics2D biContext = bi.createGraphics();
    biContext.drawImage(img, 0, 0, null);Greets
    PuceThis works fine; but has anybody else noticed this takes an unreasonable amount of time? How to get around this?

  • Converting an image to a buffered image

    is there a faster way to convert an image into a buffered image. Ive looked around and the general solution is:
    BufferedImage bi = new BufferedImage(image.getWidth(), image.getHeight(),
    BufferedImage.TYPE_INT_RGB);
    Graphics2D g = bi.createGraphics();
    g.drawImage(image, 0, 0, null);
    but that loads up 2 different varibles, g and bi, and this is going to be going in a loop. im under the impression 2 varibles is gonna slow it down, and the more fps i can get the better. I saw something about ImageIO, but from what i could gather that had to use url or stored file, rather than a Image type varible. whats the fastest whay to get a buffered image from an image. thx

    Presumably you are loading the image from a file or something.
    Why don't you load it directly into a buffered image using ImageIO? All you need to write is
    import javax.imageio.ImageIO;
    BufferedImage image = ImageIO.read(parameters...);
    there are several overloads, check the definitions here http://java.sun.com/j2se/1.5.0/docs/api/javax/imageio/ImageIO.html
