Constructor & Destructor Documentation

vil3d_meta_image::vil3d_meta_image ( const vil3d_meta_image_header header,
const vcl_string &  fname 
)

Member Function Documentation

virtual char const* vil3d_meta_image::file_format ( ) const [inline, virtual]

Return a string describing the file format.

Only file images have a format, others return 0

Reimplemented from vil3d_image_resource.

Definition at line 186 of file vil3d_meta_image_format.h.

virtual vil3d_image_view_base_sptr vil3d_meta_image::get_copy_view ( unsigned  i0,
unsigned  ni,
unsigned  j0,
unsigned  nj,
unsigned  k0,
unsigned  nk 
) 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 vil3d_image_resource.

bool vil3d_meta_image::get_property ( char const *  label,
void *  property_value = 0 
) const [virtual]

Extra property information.

This will just return the property of the first slice in the list.

Implements vil3d_image_resource.

Definition at line 920 of file vil3d_meta_image_format.cxx.

virtual vil3d_image_view_base_sptr vil3d_image_resource::get_view ( unsigned  i0,
unsigned  ni,
unsigned  j0,
unsigned  nj,
unsigned  k0,
unsigned  nk 
) 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

 vil3d_reformat(data->get_view(..), window);
*

Reimplemented in vil3d_crop_image_resource, and vil3d_memory_image.

Definition at line 63 of file vil3d_image_resource.h.

vil3d_image_view_base_sptr vil3d_image_resource::get_view ( ) const [inline, inherited]

Create a read/write view of all the data.

Definition at line 69 of file vil3d_image_resource.h.

const vil3d_meta_image_header & vil3d_meta_image::header ( void  ) const

Get the current header information.

Definition at line 734 of file vil3d_meta_image_format.cxx.

unsigned int vil3d_meta_image::ni ( void  ) const [virtual]

Dimensions: nplanes x ni x nj x nk.

The number of pixels in each row.

Implements vil3d_image_resource.

Definition at line 716 of file vil3d_meta_image_format.cxx.

unsigned int vil3d_meta_image::nj ( void  ) const [virtual]

Dimensions: nplanes x ni x nj x nk.

The number of pixels in each column.

Implements vil3d_image_resource.

Definition at line 721 of file vil3d_meta_image_format.cxx.

unsigned int vil3d_meta_image::nk ( void  ) const [virtual]

The number of slices per image.

Implements vil3d_image_resource.

Definition at line 726 of file vil3d_meta_image_format.cxx.

unsigned int vil3d_meta_image::nplanes ( void  ) const [virtual]

Dimensions: nplanes x ni x nj x nk.

This concept is treated as a synonym to components.

Implements vil3d_image_resource.

Definition at line 711 of file vil3d_meta_image_format.cxx.

vil_pixel_format vil3d_meta_image::pixel_format ( void  ) const [virtual]

virtual bool vil3d_meta_image::put_view ( const vil3d_image_view_base im,
unsigned  i0,
unsigned  j0,
unsigned  k0 
) [virtual]

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.)

Implements vil3d_image_resource.

void vil3d_meta_image::set_offset ( const double  i,
const double  j,
const double  k,
const double  vx_i,
const double  vx_j,
const double  vx_k

Set the offset.

Note:
also sets the voxel size to vx_i, vx_j and vx_k to ensure consistency

Definition at line 760 of file vil3d_meta_image_format.cxx.

bool vil3d_meta_image::set_voxel_size ( float  vi,
float  vj,
float  vk 
) [virtual]

Set the size of the each voxel in the i,j,k directions.

You can get the voxel sizes via get_properties().

Returns:
false if underlying image doesn't store pixel sizes.

Reimplemented from vil3d_image_resource.

Definition at line 750 of file vil3d_meta_image_format.cxx.

virtual bool vil3d_image_resource::view_fits ( const vil3d_image_view_base im,

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

This includes checking that the pixel type is scalar.

bool vil3d_meta_image::write_image ( ) [private]

Methods for reading/writing image.
