Description
The effectiveness and expressiveness of digital drawing are heavily dependent on an artist’s control over their medium; pen pressure dynamics, which enables fine-tuned variation in line weight and opacity. While the use of this tool improves an artist's control, the open-source editor GIMP currently offers only limited means to visualize or adjust these pressure behaviors in real time. GIMP does support pressure-based input, however, it lacks a dedicated interface for configuring a personalized pressure profile, creating a barrier for users seeking precision comparable to commercial tools. This project addresses that gap by designing and implementing a Stylus Pressure Profiling Dock within the GIMP application environment. in addition to the implementation, this project also investigates key research questions, including how pressure data can be effectively captured from various drawing tablet devices within GIMP’s existing input architecture, and how optimization techniques can be combined with the logistic (sigmoid) function to generate an accurate, user-customizable pressure S-curve.
