unsigned  ,
unsigned  ,
unsigned  ,
unsigned  ,
unsigned  ,
enum vil_pixel_format   
) [inline, virtual, inherited]

Construct a blocked output image resource.

Returns a null resource unless the format supports blocking

Reimplemented in vil_tiff_file_format.

Definition at line 68 of file vil_file_format.h.

vil_image_resource_sptr vil_bmp_file_format::make_input_image ( vil_stream vs) [virtual]

Attempt to make a generic_image which will read from vil_stream vs.

Reads enough of vs to determine if it's this format, and if not, returns 0. If it is, returns a subclass of vil_image_resource on which get_section may be applied.

Implements vil_file_format.

Definition at line 22 of file vil_bmp.cxx.

virtual vil_pyramid_image_resource_sptr vil_file_format::make_input_pyramid_image ( char const *  ) [inline, virtual, inherited]

Read a pyramid resource from a list of image files in a directory.

... or from an image file_format that supports multiple images per file.

Reimplemented in vil_tiff_file_format, and vil_pyramid_image_list_format.

Definition at line 37 of file vil_file_format.h.

virtual vil_pyramid_image_resource_sptr vil_file_format::make_pyramid_image_from_base ( char const *  ,
vil_image_resource_sptr const &  ,
unsigned  ,
char const *   
) [inline, virtual, inherited]

Construct a pyramid image resource from a base image.

All levels are stored in the same resource file. Each level has the same scale ratio (0.5) to the preceding level. Level 0 is the original base image. The resource is returned open for reading. The temporary directory is for storing intermediate image resources during the construction of the pyramid. Files are be removed from the directory after completion. If temp_dir is 0 then the intermediate resources are created in memory.

Reimplemented in vil_tiff_file_format.

Definition at line 49 of file vil_file_format.h.

virtual vil_pyramid_image_resource_sptr vil_file_format::make_pyramid_output_image ( char const *  ) [inline, virtual, inherited]

Reimplemented in vil_tiff_file_format, and vil_pyramid_image_list_format.

Definition at line 78 of file vil_file_format.h.

char const * vil_bmp_file_format::tag ( ) const [virtual]

Return a character string which uniquely identifies this format.

E.g. "pnm", "jpeg", etc.

Implements vil_file_format.
