Performs N-D FFT interpolation any data for which fftn works. Will upsample by zero-filling, downsample by truncating high frequencies, or combine both up- and downsampling by dimension to allow arbitrary reshaping.-Performs N-D FFT interpolation on

Descr iption The C++ Bitmap Library consists of simple, robust, optimized and portable 24-bit bitmap image processing algorithms for the C++ language. Capabilities The library has the following capabilities: Read/Write 24-bit Bitmap I

对于图像的upsample和downsample程序，分别提供bilinear和pixel replication两种方式。-For images upsample and downsample program, respectively bilinear and pixel replication in two ways.
