I have an extremely elaborate resizing library, but it is so complex it would not make sense as a standard tool for common uses. (Many convolution kernels, separate windows, forward and backward mapping, separable convolutions, upsampling first for Nyquist issues, strategy phase and then concurrent filtering, etc. good work but over the top)
If nothing else, you could port Paul Heckbert’s filter program from days of yore. Check graphics gems.
