Stacking.DoStacking Method
++++++++++++++++++++++++++

Definition
""""""""""

*Namespace:* ``P1.ImageSdk``

A class to stack an rgb image and a nir images from PAS280i or the 4-band solution. The rgb image is regarded as the master image. The stacker will scale and merge the two images on to of each other into upto 2 of the 3 different formats that are supported by the stacker. What outputs to generated is setup in the :ref:`StackingOutput <doxcsid-class_p1_1_1_image_sdk_1_1_stacking_output>` struct.

.. rubric:: Parameters:

.. list-table::
	:widths: 20 80

	*
		- rgbBitmap

		- is a reference to the rgb image (this image will normally for a PAS system be a stitched image). This bitmap is expected to be an undistorted image.

	*
		- rgbCalibration

		- is a reference to a struct containing a simplifed Geometric calibration (since image is undistored already - you only need to setup focallength and pixelsize).

	*
		- nirBitmap

		- is a reference to the nir image. This bitmap is expected to be still an distorted image. The stacker will undistort the image using the geometric calibration for the nir camera.

	*
		- nirCalibration

		- is a reference to a struct containing a full Geometric calibration for the nir bitmap (the Stacker will undistort the nir image using this struct).

	*
		- stackingOutput

		- is a struct that is used to setup the types of out puts the stacker should produce. It can produce either an Rgbi or a Irg bitmap. Aisde this it can in the same process alsoe produce an ndvi bitmap if it is selected. The selected bitmaps are returned in this stract after a successful stacking
