    Abstract: A computer based graphic editor has the capability of recognizing as a single graphic object a plurality of unconnected freehand strokes such as a signature. This makes possible editing a document with a signature, for example, without the various parts of the signature becoming separated and no longer being a viable entity. A cursor pointing device, such as a mouse with a button, is used to enter the plurality of unconnected strokes. Initially, the first point p₁ at the beginning of a stroke which is the first stroke of a plurality of unconnected strokes is read and stored with the visible attribute. As long as the mouse button is pressed, the position of the cursor is monitored and lines drawn from each successive point to the next point p₂ with each point p₂ being stored with the visible attribute. When the mouse button is released, the last read point position p₂ is stored with the invisible attribute. When the mouse button is pressed again, the first point p₁ of the next stroke is read and stored with the visible attribute, and the process repeated. When the mouse button is again pressed and released, the ending position of the previous stroke p 0̸ , the starting position of the current stroke p₁ and the ending position of the current stroke p₂ are compared and, if p₁ and p₂ are within a tolerance range and there exist no other points between p₁ and p₂ and if p₁ and p 0̸ are within the tolerance range, then the termination of the signature is detected.

    Abstract: A method for the intelligent, in-line dynamic editing of documents containing mixed object types on a computer work station is disclosed. The mixed object types may be text objects, draw graphics objects, business graphics objects, and tables objects. The editor executes actions on user selected objects and attributes based on user selected objects and attributes based on internal knowledge of the object type selected rather than by explicit user commands. This procedure provides a simple user interface that makes manipulation of objects and attributes and command execution transparent to the user.
