// NAME 
//  BoxFilter.h -- separable box filter (moving average convolution) 
// 
// SPECIFICATION 
//  void BoxFilter(CImageOf& src, CImageOf& dst, 
//                 int xWidth, int yWidth, bool average) 
// 
// PARAMETERS 
//  src                 source image 
//  dst                 destination image 
//  xWidth, yWidth      horizontal and vertical box widths 
//  average             scale result down by 1/(xWidth * yWidth) 
// 
// DESCRIPTION 
//  Performs a separable box filtering using efficient running sum code. 
// 
//  Because a temporary row buffer is used, the src and dst images can be the same 
//  (in place convolution). 
// 
//  If dst is not of the right shape, it is reallocated to the right shape. 
// 
//  The padding type of src (src.borderMode) determines how pixels are 
//  filled. 
// 
// SEE ALSO 
//  BoxFilter.cpp       implementation 
//  Image.h             image class definition
