Member Function Documentation

char const * vil1_jpeg_file_format::tag

(

)

const [virtual]

Return a character string which uniquely identifies this format.

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

Implements vil1_file_format.

Definition at line 47 of file vil1_jpeg.cxx.

vil1_image_impl * vil1_jpeg_file_format::make_input_image

(

vil1_stream *

vs

)

[virtual]

Attempt to make a generic_image which will read from vil1_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 vil1_image_impl on which get_section may be applied.

Implements vil1_file_format.

		int	planes,
		int	width,
		int	height,
		int	components,
		int	bits_per_component,
		enum	vil1_component_format
	)			[pure virtual, inherited]

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...
