    Exclamation get rgb values from getSnapshot()

    hi,

    i have this code snippet:

    Code:
    byte snap[] = videoControl.getSnapshot("encoding=png");
    Image img = Image.createImage(snap, 0, snap.length);
    
    int pixelValues[] = new int[img.getWidth * img.getHeight);
    img.getRGB(pixelValues, ...);
    in which the array pixelValues[] will have the RGB data of each pixel in the image. the problem is that my application slows down at createImage(), considering that this snippet loops. i don't really need to display the image.

    i know that snap[] contains the data of the image encoded in png format.

    my question is, is there a way to obtain the RGB pixel values straight from snap[] without using createImage()? code would be very much appreciated.

    advance thanks!
