Manipulate the image(s)

When you have scanned or loaded images in Dynamic Web TWAIN, you can start manipulating the images.

  1. Go through each image by changing the property CurrentImageIndexInBuffer

    /* Show the 3rd image in the buffer */
    DWObject.CurrentImageIndexInBuffer = 2;
    
  2. Show multiple images by changing the view mode (other than 1 by 1 or -1 by -1) using SetViewMode()

    /* Show 4 images in the viewer 2 by 2*/
    DWObject.SetViewMode(2, 2);
