A nearest spatial upsampling filter.


class MPSCNNUpsamplingNearest : MPSCNNUpsampling


This filter can be used to resample an existing MPSImage using a different sampling frequency for the x and y dimensions with the purpose of enlarging the size of an image.

The number of output feature channels remains the same as the number of input feature channels.

The scaleFactor must be an integer value >= 1. The default value is 1.
