[comp.graphics] Looking for literature of graphics editors

riemann@gmdzi.UUCP (Claus Riemann) (02/16/89)

A long time ago I began to implement an object-oriented graphics 
editor!
Is there any literature (also articles) dealing with this subject?

Any hints or references are welcome.

Thanx in advance,
             Claus Riemann
