    Re: Save image in record store

    There u go--->

    public boolean cacheImages(String ImageName,Image img)
    int width = img.getWidth();
    int height = img.getHeight();
    byte[] outputRecord;
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    DataOutputStream outputDataStream =new DataOutputStream(outputStream);
    int[] imgRgbData = new int[img.getWidth() * img.getHeight()];

    try {

    img.getRGB(imgRgbData, 0, width, 0, 0, width, height);

    } catch (Exception e) {
    // Problem getting image RGB data
    try {
    // Write image data to output stream (in order to get
    // the record bytes in needed form)
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream dos = new DataOutputStream(baos);

    for (int i = 0; i < imgRgbData.length; i++) {

    // Open record store, create if it doesn't exist
    rms.addRecord(baos.toByteArray(), 0,baos.toByteArray().length); // Add record

    } catch (RecordStoreException rse) {
    // Other record storage problem
    return false;
    } catch (IOException ioe) {
    // Problem writing data
    return false;

    return true;

    Write the image in a byte array format. Also store the image name, and the form factor(width, height) as they will be usefull while reading the images from the rms.

    Hope this helps

    Hii Nimesh,
    it is not wise to store images in record store because of the size limit.Just store these images in the phones and just store the URL of these images in the record store...I think this is very better when compared to the other one.
