Example
-------

To run this example in command-line, use the following: 
::

	otbcli_ConvertSensorToGeoPoint -in QB_TOULOUSE_MUL_Extract_500_500.tif -input.idx 200 -input.idy 200

To run this example from Python, use the following code snippet: 

::

	#!/usr/bin/python

	# Import the otb applications package
	import otbApplication

	# The following line creates an instance of the ConvertSensorToGeoPoint application 
	ConvertSensorToGeoPoint = otbApplication.Registry.CreateApplication("ConvertSensorToGeoPoint")

	# The following lines set all the application parameters:
	ConvertSensorToGeoPoint.SetParameterString("in", "QB_TOULOUSE_MUL_Extract_500_500.tif")

	ConvertSensorToGeoPoint.SetParameterFloat("input.idx", 200)

	ConvertSensorToGeoPoint.SetParameterFloat("input.idy", 200)

	# The following line execute the application
	ConvertSensorToGeoPoint.ExecuteAndWriteOutput()
