All white image is not rejected #306

Closed gfiumara closed 2 years ago

gfiumara commented 3 years ago

A blank image will not be rejected by the library. This is in violation of 29794-4 in that all rows and columns of a pure white image should be cropped, resulting in a 0x0 image. Instead, the image is passed as-is, and later computations fail.
