RASTR is a powerful web-based tool built on p5.js, designed to transform text into captivating geometric graphics and kinetic motion art based on the custom rasterization algorithm. The program allows users to choose from an extensive library of fonts available on Google Fonts, or to upload their custom fonts, for a personalized touch to the final result.

The tool also offers a range of export options, allowing users to save their creations in high-quality vector SVG or bitmap PNG formats. For animations, users can export in high-resolution MP4 format or select a WebP/PNG sequence. In addition, it provides the ability to export and import program settings as custom presets in JSON format. This feature allows users to save their text and graphical settings so that they can easily access them when needed.


BASIC USE:

For a quick start, I suggest exploring the PRESETS section. This will give you an idea of the tools' features, as well as allow you to make something of your own using off-the-shelf solutions.

When entering the text in the Prompt Text field, it automatically wraps within the canvas. But if you want to move the text to a new line manually, use the /n combination inside the string.

The Rasterization Quality sliders, located directly below the Prompt Text, controls the number of particles during text rasterization. The higher its value, the more particles will reproduce the text shape and the more detailed the result will be. But it directly affects performance, especially if the real-time rendering is in effect.

The program includes built-in performance optimization. Depending on the selected format type in the EXPORT section, it will either display a static image or render the animation in real-time.

• For static exports (such as PNG or SVG), the canvas stays static and is only updated when any of the interface parameters change. This reduces unnecessary processing and lowers power usage. You can also use the Select Frame option in the EXPORT section to choose which frame to export.
  
  
• For animated exports (MP4 or WEBP/PNG sequences), the program automatically switches to real-time rendering, allowing you to preview the animation live on screen.
