Abstract
A method and apparatus for producing a stroked-based font defined by a stroke representation displayable on high or low-resolution output device. The stroke representation includes defining a basic stroke with key points and width values as its primary parameters and feature points and curve ratios stored in a predefined curve level tree type data structure as its secondary parameters. Curve ratios are retrieved from the curve level table according to resolution level of the output device. Also, hinting information for certain key points provides for a better displayed stroke in low resolution space. Hinting information is activated according to predefined data associated with the curve level table. A CAD tool allows a font designer to easily select the parameters for the design of basic strokes and stroke shapes. The CAD tool presents a real-time display of sample characters at various bitmap sizes during font creation.
