{
    // LoadInMemory parameter is set to true in order to be able to update the input file.
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image_1080x720.jpg", true);
 
    // Setg the blur intensity of the gaussian filter.
    int kernel = 20;
 
    // Set the region of interest.
    gdpictureImaging.SetROI(300, 200, 500, 150);
    // Applying the gaussian filter to the ROI.
