◆ makePixelToTanPixel()

lsst.afw.cameraGeom._makePixelToTanPixel.makePixelToTanPixel ( bbox,
orientation,
focalPlaneToField,
pixelSizeMm )
Make a Transform whose forward direction converts PIXELS to TAN_PIXELS
for one detector.

Parameters
----------
bbox : `lsst.geom.Box2I`
    Detector bounding box.
orientation : `lsst.afw.cameraGeom.Orientation`
    Orientation of detector in focal plane.
focalPlaneToField : `lsst.afw.geom.TransformPoint2ToPoint2`
    A transform that converts from focal plane (mm) to field angle
    coordinates (radians) in the forward direction.
pixelSizeMm : `lsst.geom.Extent2D`
    Size of the pixel in mm in X and Y.

Returns
-------
transform : `lsst.afw.geom.TransformPoint2ToPoint2`
    A transform whose forward direction converts PIXELS to TAN_PIXELS.

Notes
-----
PIXELS and TAN_PIXELS are described in the CameraGeom documentation under
:ref:`camera coordinate systems<section_Camera_Coordinate_Systems>`.
