Abstract:
This dissertation addresses the problem of creating pen-and-ink style illustrations on a
computer by means of a high-level user interface. We present a system in which the user
creates illustrations starting from greyscale images. The user specifies the texture and orientation of components within an image by interacting with a painting-style interface. The system then transforms the image into a pen-and-ink drawing by precisely placing and orienting the individual pen strokes that compose the illustration. By encoding the principles developed by pen-and-ink artists over decades, the system aims to support the creation of illustrations capable of much of the exibility and power of traditional pen and ink.
