zyimage(data, rect, proj, x=0)
zyimage(data, (z0, y0, d, h), (xz, yz)) plots an image in the zy-plane projected to the paper plane by x' = x + xz*z, y' = y + yz*z.
The image must be YxXxC, where c=1 for grayscale, c=2 for grayscale+alpha, c=3 for rgb, c=4 for rgb+alpha. The image may be either uint8 or float.
If d is negative, the image is flipped in the z-dimension.
If h is negative, the image is flipped vertically.
Optional argument x specifies x-axis intersect of the image plane.
If None is given as a second argument, the pixel size of the image is used.
