Monotype specializes in digital typesetting and typeface design for use with consumer electronics devices. Working with both the font tools group and Display Imaging I have produced many key technologies including:• Glyph contour Conversion Library. Genetic Algorithm for Conversion between quadratic Bezier splines and cubic Bezier splines with maximum fidelity using minimal control points. Patent awarded.• GPU rasterization of glyphs. Conversion of glyph contour data into raster image in GPU shader. Patent applied for. C++, GLSL.• Library for finding similarly shaped contours in TrueType data, so that it can be compressed on disk. C++, python.• Generation of signed distance fields from glyph data. Patent Applied for. C++.• Algorithm to generate multi-channel distance fields from glyph data. C++.• Generation of signed distance field on the GPU using compute shaders. C++, GLSL.

• Glyph contour Harmonization tool. A tool to re-encode families of TrueType font data such that all contours of each glyph in the family have the same number and type of Bezier control points. These coherent contours can now be used as source data for a single, variable font. Patent applied for. Xojo, C++, OpenGL.• Rapid Intersection library. Library to discover intersections between very large sets of quadratic and cubic Bezier curves and line segments. C++ with Python bindings.• Library for finding similarly shaped contours in TrueType data, so that it can be compressed on disk. C++, python.
