The VORT file format is designed to be byte independant and easily extendable. A VORT file is made up of objects. The first byte of an object gives its type, the second byte gives the number of bytes in the size of the object, the next n bytes give the object's size, and the next size bytes gives the object. Values are written out highbyte first.
Programmes can ignore unknown fields by reading the size and skipping the object.
The first object in a VORT file should always be a direc- tory. Directories can be made up of simple objects or other direc- tories. The following types can be found in an image object. The following types can be found in a text object.
