the probelm is:
when i use a image, to initial the Surface,
error was arise:
_UFuncTypeError: Cannot cast ufunc 'add' output from dtype('float64') to dtype('uint8') with casting rule 'same_kind'_
after look for the source code, I find the problem of source code:
np.dstack([image, 255 * np.ones((h, w))])
the input image' shape is [w, h, 3], type is np.uint8
I change the code to:
np.dstack([image, 255 * np.ones((h, w), dtype=np.uint8)])
