Template Function lsst::afw::math::warpCenteredImage

Function Documentation

template<typename DestImageT, typename SrcImageT>
int lsst::afw::math::warpCenteredImage(DestImageT &destImage, SrcImageT const &srcImage, lsst::geom::LinearTransform const &linearTransform, lsst::geom::Point2D const &centerPosition, WarpingControl const &control, typename DestImageT::SinglePixel padValue = lsst::afw::math::edgePixel<DestImageT>(typename lsst::afw::image::detail::image_traits<DestImageT>::image_category()))

Parameters

  • destImage: remapped image

  • srcImage: source image

  • linearTransform: linear transformation to apply

  • centerPosition: pixel position for location of linearTransform

  • control: control parameters

  • padValue: use this value for undefined (edge) pixels

Warp an image with a LinearTranform about a specified point.

This enables warping an image of e.g. a PSF without translating the centroid.
