template<typename ImagePixelT>
int lsst::coadd::utils::copyGoodPixels(lsst::afw::image::MaskedImage<ImagePixelT, lsst::afw::image::MaskPixel, lsst::afw::image::VariancePixel> &destImage, lsst::afw::image::MaskedImage<ImagePixelT, lsst::afw::image::MaskPixel, lsst::afw::image::VariancePixel> const &srcImage, lsst::afw::image::MaskPixel const badPixelMask)

copy good pixels from one masked image to another

Parameters

• destImage: image to be modified

• srcImage: image to copy

• badPixelMask: skip input pixel if src mask & badPixelMask != 0

Good pixels are those for which mask & badPixelMask == 0.

Only the overlapping pixels (relative to the parent) are copied; thus the images do not have to be the same size.

Return

number of pixels copied
