page 10) that in Brotsky, the user can select a field of
reference to data during the rendering of the representation,
and relies on Figures 3 and 5-7 of Brotsky, as well as the
statement in Brotsky (col. 8, lines 10-13) that the ACG or
source node contents can be modified at any time.
From our review of Brotsky, we find (col. 3, lines 27-54)
that a graphics editor generates the ACG. The ACG includes
three types of nodes, i.e., source nodes representing image
fragments, transform nodes, and sink nodes which are viewable
images. The complex image represented by the ACG can be
constructed and displayed in a viewer by running the ACG. The
ACG is constructed in a graph view window (Figure 2) by
selecting node types and creating links or edges between the
nodes. When editing a source node, an editor window is
displayed (Figure 3) which permits the operator to edit the
contents of the source node. Brotsky further discloses (Col.
7, line 50 - col. 8, line 13) that images are created in three
stages. The stages are ACG creation and modification, image
fragment importation and editing, and image viewing. Once an
ACG has been constructed, and its content has been created for
