Detailed Description

Resize an image

Note that if the image is 4D, then only the first 3 dimensions can be resized.

Also note that if the image is down-sampled, the appropriate smoothing is automatically applied. using Gaussian smoothing.

Automatic oversampling is applied except for nearest-neighbour interpolation, which uses no oversampling.

Typical usage:

auto input = Image<default_type>::open (argument[0]);
Image::Filter::Resize resize_filter (input);
default_type scale = 0.5;
resize_filter.set_scale_factor (scale);
auto output = Image::create (argument[1], resize_filter);
 
resize_filter (src, dest);
