add_file_format()

void vil_file_format::add_file_format ( vil_file_format *  ff )

make_blocked_output_image()

vil_blocked_image_resource_sptr vil_tiff_file_format::make_blocked_output_image ( vil_stream *  , unsigned  , unsigned  , unsigned  , unsigned  , unsigned  , enum vil_pixel_format    )

overridevirtual

Construct a blocked output image resource.

Returns a null resource unless the format supports blocking

Reimplemented from vil_file_format.

Definition at line 302 of file vil_tiff.cxx.

make_input_image()

vil_image_resource_sptr vil_tiff_file_format::make_input_image ( vil_stream *  vs )

overridevirtual

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 195 of file vil_tiff.cxx.

make_input_pyramid_image()

vil_pyramid_image_resource_sptr vil_tiff_file_format::make_input_pyramid_image ( char const *  )

overridevirtual

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 from vil_file_format.

Definition at line 223 of file vil_tiff.cxx.

make_output_image()

vil_image_resource_sptr vil_tiff_file_format::make_output_image ( vil_stream *  , unsigned  , unsigned  , unsigned  , enum  vil_pixel_format  )

overridevirtual

Make a "generic_image" on which put_section may be applied.

The stream vs is assumed to be open for writing, as an image header may be written to it immediately. The width/height etc are explicitly specified, so that file_format implementors know what they need to do...

Implements vil_file_format.

inlinevirtualinherited

Reimplemented in vil_pyramid_image_list_format.

make_pyramid_image_from_base() [2/2]

vil_pyramid_image_resource_sptr vil_tiff_file_format::make_pyramid_image_from_base ( char const *  filename, vil_image_resource_sptr const &  base_image, unsigned  nlevels, char const *  temp_dir  )

overridevirtual

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 from vil_file_format.

Definition at line 259 of file vil_tiff.cxx.

vil_pyramid_image_resource_sptr vil_tiff_file_format::make_pyramid_output_image ( char const *  file )

overridevirtual

Reimplemented from vil_file_format.

tag()

char const * vil_tiff_file_format::tag ( ) const

overridevirtual

Return a character string which uniquely identifies this format.

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

Implements vil_file_format.
