I find the Help on this function to be very little. It doesn't say much about typical usage, best practise or examples.
I'm looking for a function where I can pass in an image and a set of coordinates (sub-pixel coordinates) and it would return the interpolated pixel value. I thought this vi would perform this function, but I see it only takes in integer coordinates, so where does the 'sub-pixel' claims come from? If the coordinates are not in a straight line, how does it do the interpolation in 2D? Does the interpolation method specified refer to the path interpolated between the coordinates or the method for interpolating the grey level of the pixel?
Any help would be appreciated.
PS my comment about the Help not being very helpful applies to many other vi's too. We definately need more meat in the help (use Matlab's help as an example).
