README.md

This repository contains examples demonstrating the use of Skia-Python, a Python binding for the Skia graphics library. If you're interested in learning or exploring Skia-Python, this repository offers practical examples to get started.

On Wayland-based platforms (i.e. very new Linux systems), setting SDL_VIDEODRIVER=x11 may be needed for the SDL example; the equivalent for the GLUT example is PYOPENGL_PLATFORM=glx (not needed on Fedora 40 Wayland).

The skparagraph-example example generates the below as an example of multilingual paragraph layout. Note on Linux, it is highly sensitive to locale, and you might need to unset LANG and FC_LANG if you have unusual (non-English) settings.

SkSL_ShaderMulti+SDL2.py is a port of the animation on https://shaders.skia.org/ . Run it with a number argument (0 to 6) for the 7 examples on https://shaders.skia.org/ .

draw_text_on_path.py is a simple demo, requiring skia-python m138, to draw text on a curve. The main part of functionality was removed in skia m70, but SkiaSharp decided to add it back.
