Ttf To Vlw Converter 2021

For developers needing to script the conversion (e.g., part of a CI/CD pipeline), LVGL offers lv_font_conv , a Python tool.

With TTF, one file serves all sizes (8px to 200px). With VLW, you need a separate converted file for each font size. A 16px VLW cannot be scaled to 32px; it will look jagged.

The command above creates a binary file ( Roboto20.vlw ). However, many embedded projects require the font data to be inside the code itself.

Without VLW, you would have to port the entire FreeType library (hundreds of KB) into your firmware. Using a converted VLW file reduces your renderer to a 100-line function that just draws bitmaps.
