Source string
- How much the corner(s) (on the vanishing point side of the image) should move to the horizon (i.e. the line containing the vanishing point). With 0% you will have no perspective effect at all and the vanishing point will be infinitely far away. With a sum of 100%, the 2 corner(s) and the vanishing point will be the same, resulting in a triangle instead of a trapezoid. For a pleasing effect, you should choose (a) number(s) between 0 and 35%, especially with ImageMagick as that toolkit also adds some stretching within the image.
