Adjusting vertical and horizontal keystone
1. Open the Geometry edit dialog for 2 x 2 mode. See "Selecting the geometry level ", page 70. The default selected anchor point
is the left top corner of the image.
2. If required, select another anchor point of this level (i.e. corner points). See "Selecting an anchor point", page 71.
3. Move the selected anchor point to the desired position. See "Moving an anchor point in small steps", page 72 and "Moving an

Note: Anchor points should only be moved inside the visible image area since moving an anchor point to the outside causes
loss of image content.
