        Conditional comment:

        End of conditional comment.

        convert pointcloud to a depth image. Colors are scaled to min and ax distance of
        points.
        Parameters:
        cloud - [in] cloud to convert to image
        Returns:
        image showing the pointcloud as a depth image

                                      float max)
        convert pointcloud to a depth image. Colors are scaled to min and max distance
        specified by user
        Parameters:
        cloud - [in] cloud to convert to image
        min - [in] the minimum distance corresponding to black
