About bow adjustment

A bow distortion can be adjusted so that a normal image is displayed. Positive adjustments introduce more outside bow distortion. Negative adjustments introduce more inside bow distortion.

How to adjust bow using the coordinates

1. In the Area pane, select a corner (1). Click on the radio button of your choice.

   

2. In the Orientation pane, select the desired orientation (2). Click on the radio button of your choice.

3. In the Bow - Angle/Length pane (3):

   • Change the angle of the bow adjustment. This will determine the curve of the bow.
   • Change the length (position of the handle compared to the corner point). By changing the length, the lowest point in the bow will move further or closer to the corner point.
4. Repeat for the other orientation and corners until the warping is finished.

How to adjust the corners using the Visualiser

1. Click on a handle and move it up down, left and right until the created bow matches almost with the screen.

   

   The new angle and length will be indicated in the Bow - Angle/Length pane.

2. Repeat for all other handles if necessary.
