Direction The four selectable directions make very little difference to the ﬁnal render.

Direction sets the starting direction of the canvas render.

Depth The Depth slider controls the apparent depth of the rendered canvas effect. A

higher setting here will render the canvas in a more intense fashion.

weights as a guide. Given an image that has a single color frame, AutoCrop will crop

away the frame.

and stretches the histograms to the full contrast range. See also
