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);

vil_pyramid_image_resource_sptr vil_load_pyramid_resource	(	char const *	directory_or_file,
		bool	verbose = `true`
	)		`[related]`

Load a pyramid image resource object from a file or directory.

vil_image_resource_sptr vil_new_image_resource	(	unsigned	ni,
		unsigned	nj,
		unsigned	nplanes,
		vil_pixel_format	format
	)		`[related]`

Make a new image of given format.

If the format is not scalar, the number of planes must be 1. When you create a multi-component image in this way, the vil_image_resource API will treat it as a scalar pixel image with multiple planes. (This doesn't affect the underlying data storage.)

Reimplemented in vil_memory_image.

vil_image_resource_sptr vil_new_image_resource	(	unsigned	ni,

Make a new image, similar format to the prototype.

Make a new image of given format with interleaved planes.

The format must be scalar.

vil_image_resource_sptr vil_new_image_resource_of_view ( vil_image_view_base const & view ) [related]

Make a new image resource that is a wrapper on an existing view's data.

Note:: The output will be a shallow copy of the input, so changing the pixel values of one may change the pixel value of the other. Thanks to the magic of smart pointers, the output will remain valid even if you destroy the input. When you wrap a multi-component image in this way, the vil_image_resource API will treat it as a scalar pixel image with multiple planes. (This doesn't affect the underlying data storage.)

Reimplemented in vil_memory_image.
