Function Documentation

template<class T >

void vil_fill	(	vil_image_view< T > &	view,
		T	value
	)

Fill view with given value.

O(size).

Definition at line 17 of file vil_fill.h.

template<class T >

void vil_fill_col	(	vil_image_view< T > &	view,
		unsigned	i,
		T	value
	)

Fill column i in view with given value.

O(nj).

Definition at line 145 of file vil_fill.h.

template<class T >

void vil_fill_disk	(	vil_image_view< T > &	image,
		double	ci,
		double	cj,
		double	r,
		T	value
	)		[inline]

Fills pixels in disk with centre (ci,cj), radius r, with given value.

Fills all planes of image with the value.

Definition at line 198 of file vil_fill.h.

template<class T >

void vil_fill_line	(	T *	data,
		unsigned	n,
		vcl_ptrdiff_t	step,
		T	value
	)

Fill data[i*step] (i=0..n-1) with given value.

vil_fill_line(vil_image_view<T>)

Definition at line 44 of file vil_fill.h.

template<class T >

void vil_fill_line	(	vil_image_view< T > &	im,
		int	ai,
		int	aj,
		int	bi,
		int	bj,
		T	value
	)

Fill line from (ai,aj) to (bi,bj) using Bresenham's algorithm.

Only modifies first plane.

Definition at line 55 of file vil_fill.h.

template<class srcT >

void vil_fill_mask	(	vil_image_view< srcT > &	image,
		const vil_image_view< bool > &	mask,
		srcT	value,
		bool	b = true
	)		[inline]

Writes given value into each pixel of image under the elements of the mask set to b.

If mask.nplanes()==1 then the same mask is applied to every image plane, otherwise there must be the same number of mask planes as image planes.

Definition at line 162 of file vil_fill.h.

template<class T >

void vil_fill_row	(	vil_image_view< T > &	view,
		unsigned	j,
		T	value
	)

Fill row j in view with given value.

O(ni).
