Function Documentation

vil_copy_deep() [1/4]

template<class T >

void vil_copy_deep	(	const vil_image_view< T > &	src,
		vil_image_view< T > &	dest
	)

Deep copy src to dest.

O(size).

Deep copy src to dest.

Definition at line 18 of file vil_copy.hxx.

vil_copy_deep() [2/4]

template<class T >

vil_image_view< T > vil_copy_deep

(

const vil_image_view< T > &

src

)

Create a deep copy of an image, with completely new underlying memory.

O(size).

Create a deep copy of an image, with completely new underlying memory.

Definition at line 25 of file vil_copy.hxx.

vil_copy_deep() [3/4]

bool vil_copy_deep	(	const vil_image_resource_sptr &	src,
		vil_image_resource_sptr &	dest
	)

Copy src to dest.

This is useful if you want to copy on image into a window on another image. src and dest must have identical sizes, and pixel-types. Returns false if the copy failed. O(size).

Definition at line 45 of file vil_copy.cxx.

vil_copy_deep() [4/4]

vil_image_resource_sptr vil_copy_deep

(

const vil_image_resource_sptr &

src

)

Creates an in memory vil_image_resource and copies the src to it.

The size and pixel type of the return vil_image_resource is determined by src O(size)

Definition at line 89 of file vil_copy.cxx.

vil_copy_reformat()

template<class T >

void vil_copy_reformat	(	const vil_image_view< T > &	src,
		vil_image_view< T > &	dest
	)

Copy src to dest, without changing dest's view parameters.

This is useful if you want to copy an image into a window on another image. src and dest must have identical sizes, and types. O(size).

vil_copy_to_window()

template<class T >

void vil_copy_to_window	(	const vil_image_view< T > &	src,
		vil_image_view< T > &	dest,
		unsigned	i0,
		unsigned	j0
	)

Copy src to window in dest.

Size of window is defined by src. O(src.size).

Size of window is defined by src. O(window.size).
