◆ insert_slice()

int nn4_ctfReconstructor::insert_slice	(	const EMData *const	slice,
		const Transform &	euler,
		const float	weight
	)

virtual

Insert a slice into a 3D volume, in a given orientation.

Returns: 0 if successful, 1 otherwise

Parameters

slice	the image slice to be inserted into the 3D volume
euler	Euler angle of this image slice.
weight	A weighting factor for this slice, generally the number of particles in a class-average. May be ignored by some reconstructors

Returns: 0 if OK. 1 if error.

Exceptions

NullPointerException	if the input EMData pointer is null
ImageFormatException	if the image is complex as opposed to real

Reimplemented from EMAN::Reconstructor.
