How to load a PNG image from a location in CF card

Hi,
I am using WTK 2.5.2. I wanted to load a PNG image to Image object. The image is loaded when I have it in the classes folder. But I want to select different image from a different location. If I try to open an Image to createImage(String) from a different location, I get IOException.
Please help me.
Thanks

I got the answer, I should be using Image.createImage(InputStream) API. It works fine.
Thanks

  • How to stream a png image from a Servlet to an Applet?

    Hello,
    I'm trying to write to an output stream (in my servlet) a png image created with JFreeChart library and read it from an input stream (in my applet).
    So,i'm using
    response.setContentType("image/png");
          response.setBufferSize(1000000);
          ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());
          System.out.println("starting writing image object");
          this.genPNG(chart);
          ChartUtilities.writeChartAsPNG(out, chart, 729, 447);On the applet side i'm trying to read the input stream with ImageIO.read(InputStream)
    InputStream in = servletCon.getInputStream();
          //Image case
          ObjectInputStream objInputStream = new ObjectInputStream(in);
          Object o = objInputStream.readObject();
          Image img = ImageIO.read(objInputStream);
          im = new ImageIcon(img);But nothing happens.It returns me a null object.
    On the servlet side if i write the image on disk it's ok.(This means that the servlet is doing correctly it's job of writing the image).
    Do you have any ideas and possibly 2-3 lines of code on how to write a png image in a stream and how to read the stream +reconstruct the image.
    I searched a lot but not found anything (there's something out there for jsp only).
    Thanks you in advance
    Chris

    You're right.I forgot those Object Streams because i was passing another serialized object which wasnt serializable,then i changed by passing the complete image but forgotten those streams.
    It worked gracefully with simple Input Output Streams and ImageIO.
    Thank you very much

  • How to load and retrieve images from Portal. URGENT

    Dear all,
    I've designed a table with an ordsys.ordimage field for images. BIG MISTAKE, because there is no possibility to upload images from a form. I'd like to change it into a BLOB field but an error arises:
    "You cannot modify the column definition for types CLOB, NCLOB, BFILE, BLOBand Intermedia Object types(ORDSYS.ORDIMAGE, ORDSYS.ORDAUDIO, ORDSYS.ORDVIDEO). (WWV-17079)"
    Could I change it anyhow in order not to build a new table? I have a lot of forms referring to that table and I should change these forms too....(and we know it is pretty difficult)...
    I would appreciate any help.
    Tomas

    Tomas,
    Do you have any active constraints on that specific row? If the row is accessed by other forms (tables etc) you would need to disable them (for example foreign key constraints) and update the row (or remove and re-add it).

  • Load picture control with png image from the web

    Hi guys,
    Is there an example anywhere for Labview 8.6 for loading a picture control with png image from the web?

    Hi lavalava,
    here you find a note on how to load pictures from the internet. After grabbing the data you could save them to a file, load the file with the picture file functions and then convert it into the image datatype to feed a picture indicator with the data...

  • How to create an gray scale png image from intensitie​s values

    Hi,
      I would like create a gray scale png image from set of intensities values which is saved in excel sheet . Is IMAQ tool necessary for this vi?
    thanks & regards
    Manoj

    You posted in the feedback forum, which is not correct for your question. I am guessing you are talking about LabVIEW since you mention "vi".

    The answer is NO. Plain LabVIEW is sufficient.

  • Export PDF, JPG or PNG images from the mapviewer

    hi,
    I need to export PDF, JPG or PNG images from the mapviewer (Oracle Map client).
    How Can I do it?
    Any Ideas?
    Thanks.

    What I do with xml after calling getMapAsXML function
    Any example?There is a request page in the mapviever configuration webpages, there you can send it to the server and get the image in return.
    or you can write your own programm to send it to the mapviewer servlet using post and progress the response by yourself. Have a look at the mapviewer documentation pdf, there are some examples on the different possible different xml requests.

  • How to turn off PNG Images

    How to turn off PNG Images?

    PNG is a format for (compressed) images just like the JPG format. There is no way to disable this format.
    If you have a problem with images on some web pages then you may need to block images from some domains.
    You can look at the Adblock Plus extension to block specific content.
    * Adblock Plus: https://addons.mozilla.org/firefox/addon/adblock-plus/
    You need to subscribe to a Filter list (e.g. the EasyList).

    Well I suppose the picture is stored in a blob. If that is so this is some code I have used to load a picture to a panel. Hope you find it usefull.
    PreparedStatement retreive = db.createPreparedStatement("select bl from test where ln = ?");
    Blob bl;
    try{
    retreive.setBigDecimal(1, new BigDecimal(jTFln.getText()));
    ResultSet rs = retreive.executeQuery();
    if (!rs.next())
    System.out.println("Empty Result Set");
    bl = rs.getBlob("bl");
    if (bl == null) {
    System.out.println("Null Blob");
    return;
    InputStream is = bl.getBinaryStream();
    int imageLength = (int) bl.length();
    System.out.println(imageLength);
    System.out.println(bl.length());
    byte[] imageData = new byte [imageLength];
    is.read(imageData, 0, imageLength);
    image1 = new ImageIcon(imageData);
    photo = new JPanel() {
    public void paint(Graphics g){
    g.setColor(Color.lightGray);
