The current version only supports 3x3 and 5x5 integer and floating point kernels. In the current version, kernels can only be applied to "L" and "RGB" images. :param size: Kernel size, given as (width, height). In the current version, this must be (3,3) or (5,5). :param kernel: A sequence containing kernel weights. :param scale: Scale factor. If given, the result for each pixel is divided by this value. the default is the sum of the kernel weights. :param offset: Offset. If given, this value is added to the result, after it has been divided by the scale factor.
