200 (Figures 1 and 4). A request of some type starts the image
transformation process by letting the originating device know
that the receiving device seeks image data that it can use in its
local format. The receiving device has image data in a second
raster format or “requested format,” and the originating device
has image data in a first raster format or “present format.” The
requested format 200 and the present format 100 include first and
second sets of parameter values, respectively (Figure 4). Le
Gall uses a universal conversion unit that includes a group of
algorithms/filters for converting data from one raster format out
of a multiplicity of possible raster formats to another raster
format out of the multiplicity of possible raster formats (Figure
1; column 6, lines 49 through 53). In the universal conversion
unit, Le Gall compares a plurality of predetermined
characteristics/second parameter values of the first raster
format with information explicitly identifying a plurality of
predetermined characteristics/first parameters values of the
second raster format (column 6, lines 54 through 60). Based upon
the comparison, the universal conversion unit selects a subset of
algorithms/filters from the group/library of algorithms/filters
(column 6, lines 61 and 62). The selected subset of
algorithms/filters is comprised of a subset of algorithms/filters
