Detailed Description

template<typename T, typename P>
class inviwo::TemplateImageSampler< T, P >

TemplateImageSampler<T,P> aids sampling of images of a given type (T) using Bi-Linear Interpolation with precision (P).

A helper class to aid sampling of images of a given type (T). Expects the input to be on the range [0 1]. Eg., input of (0,0) will return the color of the bottom left pixel and (1,1) will return then top right pixel. Output values are bi-linear interpolated between the 4 nearest neighbors.

The template parameter P should be either double or float. When T is either float our double P should be the same.
