13 description: Pad an image with black to fulfill the requested image size.
15 Normally resize is used to pad the producer's output to what the consumer has
16 requested after an upstream rescale filter first scales the image to maximise
17 usage of the image area. This filter is automatically invoked by the loader
18 as part of image normalisation.
