void lsst::afw::image::Mask< MaskPixelT >::conformMaskPlanes | ( | const MaskPlaneDict & | masterPlaneDict | ) |
Adjust this mask to conform to the standard Mask class's mask plane dictionary, adding any new mask planes to the standard.
Ensures that this mask (presumably from some external source) has the same plane assignments as the Mask class. If a change in plane assignments is needed, the bits within each pixel are permuted as required. The provided masterPlaneDict
describes the true state of the bits in this Mask's pixels and overrides its current MaskDict
Any new mask planes found in this mask are added to unused slots in the Mask class's mask plane dictionary.
