img_ttf_simulate()

Bimage * img_ttf_simulate	(	Bimage *	pn,
		CTFparam &	ctf,
		int	action,
		double	wiener,
		double	tilt,
		double	tilt_inc,
		double	axis
	)

Calculates an exact tilted CTF imposed image.

Parameters

*pn	image structure.
&ctf	CTF parameter structure.
action	0=apply, 1=flip.
wiener	Wiener factor.
tilt	tilt angle in radians.
tilt_inc	tilt increment per sub-image in radians.
axis	tilt axis direction in radians.

Returns

Bimage* new image.

A CTF function is calculated for each line parallel to the tilt axis,
applied to the whole image, and the transformed line written into a new image.
