Detailed Description

template<typename SrcImageIterator, typename SrcAccessor, typename MaskIterator, typename MaskAccessor, typename INTERPOLATOR>
class vigra_ext::ImageMaskInterpolator< SrcImageIterator, SrcAccessor, MaskIterator, MaskAccessor, INTERPOLATOR >

"wrapper" for efficient interpolation access to an image

Tailored for panorama remapping. Supports warparound boundary condition of left and right as well as masks

Member Function Documentation

template<typename SrcImageIterator, typename SrcAccessor, typename MaskIterator, typename MaskAccessor, typename INTERPOLATOR> bool vigra_ext::ImageMaskInterpolator< SrcImageIterator, SrcAccessor, MaskIterator, MaskAccessor, INTERPOLATOR >::interpolateInside (  int  srcx, int  srcy, double  dx, double  dy, PixelType &  result, MaskType &  mask )  const [inline]

Interpolate without boundary check.

template<typename SrcImageIterator, typename SrcAccessor, typename MaskIterator, typename MaskAccessor, typename INTERPOLATOR> bool vigra_ext::ImageMaskInterpolator< SrcImageIterator, SrcAccessor, MaskIterator, MaskAccessor, INTERPOLATOR >::operator() (  double  x, double  y, PixelType &  result, MaskType &  mask )  const [inline]

Interpolate the data item at a non-integer position x, y. It checks if the interpolation would access a pixel with alpha = 0 and returns false in that case. be careful, no bounds checking is done here. take INTERPOLATOR::size into accout before iterating over the picture. the used image pixels are [i-(n/2 -1) .. i+n/2], where n is the size of the interpolator Parameters: x  x position, relative to i and alpha.first y  y position, relative to i and alpha.first result  the interpolation result Returns: true if interpolation ok, false if one or more pixels were masked out
