bool ImageDatabase::load

(

const char *

name

)

load.

Load a database from file.

Parameters:

name	the name of the database file (a directory called name.d should also exist).

Author:

Brendan McCane

Definition at line 121 of file image_database.cxx.

bool ImageDatabase::save	(	const char *	name,
		const char *	imagetype
	)

save.

Save all images in the database. To do this, I create a single database file that has a list of label/filename pairs. I also create a subdirectory in which all the images are stored. The images are stored based on the imagetype parameter, which should be the extension of a valid image file type (eg "ppm", "pgm", "png", etc).

Parameters:

name	the name of the database file (a directory called name.d is also created).
imagetype	a valid file extension type (eg "ppm");
