System and method for representing graphical font data and for converting the font data to font instructions

摘要

The present invention provides a method for creating high-level language hinting instructions through the use of a graphical user interface. The present invention enables a user to generate complex font programs without requiring knowledge or experience in font programming. Graphical commands are entered by a user while editing a glyph. The graphical commands are converted into functional data and stored within a data structure that represents the edited glyph. The functional data is then compiled or translated into high-level language hinting instructions that can later be compiled to machine code. Specifically, this aspect of the present invention relieves the user of having to specify the order of the hinting instructions. The present invention also provides a method to translate high-level language hinting instructions into functional data. The functional data can then be used to update the display of the edited glyph. This aspect of the present invention allows experienced font programmers to modify a font program but still maintain the ability to graphically edit the font program.
