I've added the documentation from the original patch to this page:
The next text is attached below.
im.transform(size, PERSPECTIVE, data)
im.transform(size, PERSPECTIVE, data, filter)
Applies a perspective transform to the image, and places the result
in a new image with the given size.
Data is a 8-tuple (a, b, c, d, e, f, g, h) which contains the
coefficients for a perspective transform. For each pixel (x, y)
in the output image, the new value is taken from a position
(a x + b y + c)/(g x + h y + 1), (d x + e y + f)/(g x + h y + 1)
in the input image, rounded to nearest pixel.
This function can be used to change the 2D perspective of the
