DPI-awareness in Pharo

Project Idea

Due to the rise of high-resolution displays in recent years, user interfaces that use fixed pixel-sizes for drawing certain elements tend to become too small to read. While operating systems can scale them up to some degree, the results are often blurry. Instead, programmers should write code that does not rely on fixed sizes, but instead draw elements depending on the DPI values of the current screen in order to ensure readable interfaces on every display.

Pharo is currently not DPI aware. The goal of this project is to change this and add proper support for high-resolution displays to Pharo. This project may include both work on the Pharo virtual machine and within the image.

This project is intended as a seminar or bachelor thesis project.
