virtual char const* vil_image_resource::file_format ( ) const [inline, virtual, inherited]
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.

Reimplemented in vil_nitf2_image, and vil_j2k_image.

Definition at line 80 of file vil_image_resource.h.

vil_image_view_base_sptr vil_flip_ud_image_resource::get_copy_view ( unsigned  i0,
unsigned  n_i,
unsigned  j0,
unsigned  n_j 
) 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.

Definition at line 135 of file vil_flip.cxx.

virtual bool vil_flip_ud_image_resource::get_property ( char const *  tag,

vil_image_view_base_sptr vil_flip_ud_image_resource::get_view ( unsigned  i0,
unsigned  n_i,
unsigned  j0,
unsigned  n_j 
) 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);

unsigned  nj,
unsigned  nplanes,
vil_pixel_format  format 
) [related]

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.

Definition at line 32 of file vil_new.cxx.

vil_image_resource_sptr vil_new_image_resource ( unsigned  ni,

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.)
