[mask] Problem to set mask with different sizes #2286

Open vallsv opened 5 years ago

vallsv commented 5 years ago

The problem is yet i dont have an image, but i want to custom the mask.

But maybe it's the same problem if we changes the image size.

ERROR:pyFAI-calib2.UNCAUGHT:operands could not be broadcast together with shapes (1065,1030) (0,0)

As far as I remember, as it is, it does not support setting a mask while there is no image.... but it should not raise an exception (or at least a more explicit one). When there is a change of image size, the mask is clipped or expanded.
