Function Documentation

double calc_theta_mod	(	double	theta,
		double	x
	)		[inline]

Calculate theta in range 0 to x.

template<class sType , class dType >

void vimt_rotate	(	const vimt_image_2d_of< sType > &	src_image,
		vimt_image_2d_of< dType > &	dest_image,
		double	theta_deg
	)		[inline]

Rotate image by angle theta.

On exit, dest is sized to completely include rotated source. Its world2im() transformation includes that of the src and the rotation (ie world frame is preserved). Note that this currently assumes square pixels. So dest_image.world2im()=rotation*src_image.world2im()
