The ofTrueTypeFont class can load .ttf files, but it uses FreeType behind the scenes. For high performance (drawing thousands of letters), you pre-render a VLW using ofxFontStash or the built-in ofTrueTypeFont::saveFont .
Several scenarios require TTF to VLW conversion:
On the web, you simply link a Google Font. In an operating system, you install a .ttf file. But in the world of embedded electronics? You don’t have the luxury of a file system or the RAM to parse complex font files.
For VLW to other format conversions, desktop applications like Glyphs or FontForge can import VLW files and export to various standard formats.
If you are developing a project for an Arduino, a Raspberry Pi Pico, or a bare-metal microcontroller with a display, you have likely encountered a specific problem:
What are you using (Windows, Mac, or Linux)? What is the main goal of your Processing project?
ofExit(); // Quit after saving
: The most official way to convert fonts is using the "Create Font" tool built directly into the Processing IDE Open Processing, go to Tools > Create Font
which details using the Processing "Create Font" method for anti-aliased "Smooth Fonts" on embedded displays. István Horváth’s Converter (Developer Tool)
: Click OK to create the VLW file in your project folder. Method 2: Use Online Converters If you do not have Processing, you can use a website. Search : Look for a free "TTF to VLW converter" online. Upload : Drag your TTF file onto the website. Convert : Click the start button. Download : Save the new VLW file to your computer. Tips for Best Results
If successful, you will now have an executable file named fontconvert in that directory.
Ideal for low-power microcontrollers (like ESP32 or Wio Terminal) that lack the CPU power to render vectors in real-time.
The Ultimate Guide to TTF to VLW Converters: How to Convert Fonts for Processing
Engineers building interfaces for thermostats, medical devices, or car dashboards use LVGL. LVGL requires VLW fonts. You design your UI on a PC using a nice TTF font (like Roboto or Montserrat), then convert that TTF to VLW at specific sizes to upload to your board.
Building a custom handheld game console? You need a pixel-perfect UI. By converting a TTF to VLW, you can render text without taxing the main game loop.
