template<typename DestImageT, typename SrcImageT>
int lsst::afw::math::warpImage(DestImageT &destImage, SrcImageT const &srcImage, geom::TransformPoint2ToPoint2 const &srcToDest, WarpingControl const &control, typename DestImageT::SinglePixel padValue = lsst::afw::math::edgePixel<DestImageT>(typename lsst::afw::image::detail::image_traits<DestImageT>::image_category()))

A variant of warpImage that uses a Transform<Point2Endpoint, Point2Endpoint> instead of a pair of WCS to describe the transformation.

Return

the number of good pixels

Parameters

  • [inout] destImage: Destination image; all pixels are set

  • [in] srcImage: Source image

  • [in] srcToDest: Transformation from source to destination pixels, in parent coordinates; the inverse must be defined (and is the only direction used). makeWcsPairTransform(srcWcs, destWcs) is one way to compute this transform.

  • [in] control: Warning control parameters

  • [in] padValue: Value used for pixels in the destination image that are outside the region of pixels that can be computed from the source image
