xzimage(data, rect, proj, y=0)
xzimage(data, (x0, z0, w, d), (xz, yz)) plots an image in the xz-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 w is negative, the image is flipped right to left.
If d is negative, the image is flipped in the z-dimension.
Optional argument y specifies y-axis intersect of the image plane.
If None is given as a second argument, the pixel size of the image is used.
