Detailed Description

template<typename T, class Tstate = bbstate_idx<T>>
class ebl::resizepp_module< T, Tstate >

Resize the input to the desired output (while preserving aspect ratio) and apply a preprocessing module. This is useful because in some situations preprocessing needs to be done within the resizing operation. e.g. when resizing while preserving aspect ratio, the output must eventually be copied into the true desired output dimensions, but preprocessing must be done before copying it to avoid edge detection between the empty parts of the image.
