Up: No Title Previous: Efficiency vs Incapsulation

Recomendations

We feel that there has not been strong communication between the (u, v) group and the Image group. The Image group has created an independent system of code which is logically consistent but does not mesh very well with the requirements of the (u, v) data group. The (u, v) group developed its code with a DummyImage class which was very simple and supplied us with everything we needed. In retrospect, the (u, v) group should have asked the Image group to supply certain data members and functions in a preliminary image class so the Image class and one of its primary clients could evolve together.

At this point, we feel strongly that the coordinate systems and Image classes need to be thought about in terms of ease of use, minimization of confusion, and the capability of writing efficient code without breaking the encapsulation of the Image class. We do not like the ImPixel coordinate system, but we are open to solutions which use the ImPixel system if our objections can be met.
