That's a hard one Gino.
Just tell them
The present invention provides an apparatus and method for converting font outlines to rasterized bit maps. The method accesses stored outline data representing the object in a first coordinate space and transforms the outline data to corresponding data representing the object in a second coordinate space, maintaining regional relationship information in both coordinate spaces, through a non-linear transformation expressed as a plurality of linear transformation matrices, to generate a bit map suitable for displaying the object. The present invention includes an apparatus to analyze Bezier curves and subdivide them as necessary until each portion is sufficiently flat to be approximated as a straight line, and then to calculate where line segments cross pixel midlines in order to fill the outline and generate the bit map. From another perspective, the method takes an outline of an object in a first coordinate space, scales the outline to a second coordinate space, identifies the coordinates of one or more select points in the second coordinate space and compares those coordinates with desired coordinates in the second coordinate space, calculates the difference in device space for the desired versus the actual coordinate in the second coordinate space, derives a plurality of piecewise linear transformation matrices to approximate a non-linear transformation, applies an appropriate linear transformation matrix to map essentially any point on the outline in the first coordinate space to corresponding coordinates in the second coordinate space, and fills and stores the outline of the object in a form suitable for display on a raster device.
lol... i found that when i googled "converting a font to outlines" ....it sounds good
