    Serious Problem with Images


    Hi friends,
    I'm having one serious problem while dealing images. I 'm in need to find
    the size of the image occupied in memory. How to find that.


    Also, how to find the properties of the image which should provide number
    of colors for that image ? That is, by using pixel grabber class, we can
    get the individual pixel and do the calculation, but that will be giving
    only the number of colors used in the image. But, what I need is total number
    of colors., irrespective of used or unused.

    thanks in advance

    Hello,
    getting the size of an image sometimes causes troubles
    heres a trick I learned to overcome

    // creating image
    Image theImage = createImage(somewidth, someheight);

    ..... etc ... etc

    // get sizes
    while(theImage.getWidth(null) == -1){}
    while(theImage.getHeight(null) == -1){}
    int width = theImage.getWidth(null);
    int height = theImage.getHeight(null);

    As for other question dont quite understand what you want,
    hope this was of some help
