Abstract [en]

Stylized Stroke Fonts (SSF) are stroke fonts which allow variable stroke widths and arbitrary stroke ends. In this thesis project we implement SSF by extending concepts of the traditional vector graphics paradigm, giving what we call Vector Graphics Stylized Stroke Fonts (VGSSF). A stroking algorithm for the new stroke model is developed and implemented in the Opera web browser's internal vector graphics drawing toolkit. Both the HTML 5 Canvas JavaScript interface and SVG fonts are extended to support the new stroke model. An editor and renderer for the SVG font format is implemented inside the browser using the extended Canvas interface. Sample glyphs from Latin and Chinese typefaces are converted to the SVG font format to assess the suitability of the stroke representation. The results are excellent for Chinese Ming typeface glyphs, while there are some minor problems with Latin typeface glyphs. Approximations suggest that VGSSF gives a size reduction of the font definition file by at least 50%, with a potential reduction of around 85% for Chinese typefaces. The processing requirements increase by approximately 20-30% due to extra steps required to render each glyph.
