	)			const `[inline, virtual, inherited]`

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 in vil_dicom_image, vil_clamp_image_resource, vil_crop_image_resource, vil_decimate_image_resource, vil_flip_lr_image_resource, vil_flip_ud_image_resource, vil_memory_image, vil_plane_image_resource, and vil_transpose_image_resource.

Definition at line 64 of file vil_image_resource.h.

	)			const `[pure virtual, inherited]`

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.

vil_image_view_base_sptr vil_image_resource::get_copy_view ( ) const [inline, inherited]

Create a read/write view of a copy of all the data.

virtual bool vil_image_resource::put_view	(	const vil_image_view_base &	im,
		unsigned	i0,
		unsigned	j0
	)			`[pure virtual, inherited]`

Put the data in this view back into the image source.

The view must be of scalar components. Assign your view to a scalar-component view if this is not the case.

Returns:: false if failed, because e.g. resource is read-only, format of view is not correct (if it is a compound pixel type, try assigning it to a multi-plane scalar pixel view.)

virtual bool vil_image_resource::put_view ( const vil_image_view_base & im ) [inline, virtual, inherited]

Put the data in this view back into the image source at the origin.

Reimplemented in vil_j2k_image.

bool vil_image_resource::view_fits	(	const vil_image_view_base &	im,
		unsigned	i0,
		unsigned	j0
	)			`[virtual, inherited]`

Check that a view will fit into the data at the given offset.

This includes checking that the pixel type is scalar.
