This is parag. 6 of ntrivedi's report.doc section on Limitations:

One goal of part of the 03f bde2java team is to add the coord 
transforms between world coordinates and link or device coordinates 
to achieve bde .dat file compatibility.
These functions in bde/src are called WCtoLC, LCtoWC, WCtoDC, DCtoWC.


6.      The test files JParchitecture.dat and histogram.dat 
did not work in bde2java. Bde2java's single -diagram .dat files 
appear to use absolute pixel coordinates throughout. 
Bdeunix .dat files have float values in world coordinates 
and load a file with multiple graphs then render one via a 
WCtoDC transformation to pixel device coords.

(Genjava could do this also  but is not used by bde2java.). 
[RJL: How? genjava knows nothing  about canvas WC/DC/LC coordinates?]

.dat file compatibility may be true of bdevcpp but not bde2java. 
Prof. Lechner and I had talked on this issue and verified it 
using some sample data files and creating some more on BDE2Java2.

[RJL: WCtoDC and DCtoWC merely convert between int and float 
with optional scale up/down by 2 or 4. 
WC does not mean shringing the canvas to a [0..1] float square.]
