They look perfectly sharp at any size, from tiny footnotes to massive billboards.
If you really need to write one, study ( PFont.java , VLWFont.java , FontImporter.java ) and the OpenJDK SunFontManager for outline flattening logic. ttf to vlw converter

The font looks identical across different machines and operating systems.
Converting TrueType (.ttf) fonts to the format—a bitmap font format primarily used by the Processing Issues like missing characters (displayed as square boxes)
Tools like Fontsource Converter are better for optimizing web fonts, but for pure Processing, tools that explicitly support .vlw output are better. How to Use the Converted VLW File in Processing
If you encounter issues during the conversion process, here are some troubleshooting tips:
Always test converted VLW fonts in your target environment. Issues like missing characters (displayed as square boxes) typically indicate that the character wasn't included in the conversion range or that the source TTF file lacks that glyph.
