virtual unsigned vil_plane_image_resource::nplanes ( ) const [inline, virtual]

Dimensions: Planes x ni x nj.

This concept is treated as a synonym to components.

Implements vil_image_resource.

Definition at line 62 of file vil_plane.h.

virtual unsigned vil_plane_image_resource::ni ( ) const [inline, virtual]

Dimensions: Planes x ni x nj.

The number of pixels in each row.

Implements vil_image_resource.

Definition at line 63 of file vil_plane.h.

virtual unsigned vil_plane_image_resource::nj ( ) const [inline, virtual]

Dimensions: Planes x ni x nj.

The number of pixels in each column.

Implements vil_image_resource.

Definition at line 64 of file vil_plane.h.

virtual enum vil_pixel_format vil_plane_image_resource::pixel_format ( ) const [inline, virtual]

Pixel Format.

A standard RGB RGB RGB of chars image has pixel_format() == VIL_PIXEL_FORMAT_BYTE

Implements vil_image_resource.

virtual vil_image_view_base_sptr vil_plane_image_resource::get_copy_view	(	unsigned	i0,
		unsigned	ni,
		unsigned	j0,
		unsigned	nj
	)			const `[virtual]`

Create a read/write view of a copy of this data.

This function will always return a multi-plane scalar-pixel view of the data.

Returns:: 0 if unable to get view of correct size, or if resource is write-only.

Implements vil_image_resource.

virtual vil_image_view_base_sptr vil_plane_image_resource::get_view	(	unsigned	i0,
		unsigned	ni,
		unsigned	j0,
		unsigned	nj
	)			const `[virtual]`

Create a read/write view of the data.

Modifying this view might modify the actual data. If you want to modify this data in place, call put_view after you done, and it should work efficiently. This function will always return a multi-plane scalar-pixel view of the data.

Returns:: 0 if unable to get view of correct size, or if resource is write-only.

If you want to fill an existing view (e.g. a window onto some other image), then use

   vil_reformat(data->get_view(..), window);

Reimplemented from vil_image_resource.

virtual bool vil_plane_image_resource::put_view	(	const vil_image_view_base &	im,
