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: An electronic text-graphic editing system which includes a mixed object editor which flows text around and into irregularly shaped graphic objects on a page so that all the "white" space on the page is filled. An irregularly shaped window which generally conforms to the shape of the graphic object is first created. Then the boundaries of text lines which intersect the irregularly shaped window are determined. Text is next placed in the available text space.

Abstract: A procedure for generating a mirror image of a graphic object on an interactive computer graphics display is disclosed. In the specific example described, a cursor locating device such as a mouse and an all points addressable display are assumed. The graphics object for which the mirror image is to be generated is selected by means of the pointing cursor. The mirror image function is also selected by means of the pointing cursor. This causes a default mirror image to be generated on the display along with the original image of the selected graphics object. In addition, a "mirror" with a direction handle and an angle handle is displayed in a window on the display. Either of these handles may be "grabbed" by selecting with the pointing cursor and then rotated to manipulate the generated mirror image and the selected object on the display. When the direction handle is rotated, the generated mirror image and the selected object are simultaneously rotated in the plane of the display. When the angle handle is rotated, the generated mirror image and the selected object are simultaneously stretched or shrunk depending on the direction of rotation to provide a "butterfly" effect.
