Detailed Description

template<typename MaskPixelT = lsst::afw::image::MaskPixel>
class lsst::afw::image::Mask< MaskPixelT >

Represent a 2-dimensional array of bitmask pixels.

Some mask planes are always defined (although you can add more with Mask::addMaskPlane):

• BAD This pixel is known to be bad (e.g. the amplifier is not working)
• CR This pixel is contaminated by a cosmic ray
• DETECTED This pixel lies within an object's Footprint
• DETECTED_NEGATIVE This pixel lies within an object's Footprint, and the detection was looking for pixels below a specified level
• EDGE This pixel is too close to the edge to be processed properly
• INTRP This pixel has been interpolated over

  Note

  should be called INTERPOLATED

• SAT This pixel is saturated and has bloomed

  Note

  should be called SATURATED

• SUSPECT This pixel is untrustworthy, and you may wish to discard any Source containing it

conformMaskPlanes()

template<typename MaskPixelT >

void lsst::afw::image::Mask< MaskPixelT >::conformMaskPlanes

(

const MaskPlaneDict &

)

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.

Parameters

masterPlaneDict

mask plane dictionary currently in use for this mask

Return a subimage corresponding to the given box.

This method is wrapped as getitem in Python.

Note

This method permits mutable views to be obtained from const references to images (just as the copy constructor does). This is an intrinsic flaw in Image's design.
