Above/Below (F10)

The images are displayed above/below each other without any third composite image.

Using the left,right,up,down arrow-keys the image may be moved horizontally to increase/decrease the stereo disparity and vertically to eliminate disparity errors.

The left-arrow key moves the images towards each other, the right-arrow key moves them away from each other.

Initially, the window title-bar displays the name of the file (prefixed 'Left' and 'Right' in the case of stereo-format),start-frame/current-frame/end-frame numbers, frame width and height in pixels and Parallel or Cross-eyed viewing.

As soon as an alignment-key is pressed, this changes to display the original frame-size and size after alignment.
