This demo displays most of the Skia/Skija APIs and is an excellent learning resource.

LWJGL example requires latest master build of Skija installed locally:

./script/install.sh

Alternatively, you can use pre-built Skija. In pom.xml replace skija-native dependency with:

<artifactId>	<version>
skija-macos
skija-linux
skija-windows

Then:

cd examples/lwjgl
./script/exec.sh
