The main objective was to create a lightweight drawing application while experimenting with my newly developed UI library (see github.com/pcapurro/sdl-cpp). Developing the application required designing numerous custom widgets, implementing multiple painting tools, building a complex component hierarchy with custom behaviors, and developing a fully asynchronous multi-window system.
The project is written for Linux. You need the following packages (SDL2):
libsdl2-dev libsdl2-ttf-dev libsdl2-image-dev
Use make to compile the software. Type ./paint-software to launch.
At start, the software will ask you the name of your project (the name of the exported .png file) and the dimensions (px) of your painting.
Main tools:
– Brush and pencil,
– Bucket (span fill algorithm) and spray,
– Eraser and color picker,
– Line and square.
Others:
– Export (.png),
– Undo/Redo history (Ctrl+Z / Ctrl+Y),
– Alpha channel support,
– Brush opacity and size settings slider,
– Color selection.
You can use F5 to generate a new color randomly.
Note
The software interface is inspired by Apple's MacPaint (1984).
It is an independent implementation and is not affiliated with Apple Inc.
The software uses the Open Sans typeface by Steve Matteson.
All the other assets (icons and buttons : see materials/) have been made by myself from scratch using GIMP software.
