The Ink library is a freehand stroke generation library. It produces smoothed, modeled stroke shapes with brush effect shaders as mesh-based vector graphics.
This provides the core of the implementation of the Android Jetpack Ink library. While the implementation is well-tested, the developers of this library are not currently making hard guarantees about interface stability.
ANDROID_NDK_HOME to point to it.sdkmanager or Android Studio: https://developer.android.com/studio/projects/install-ndksudo apt-get install libtinfo5Ink can be built and tested from the repo root:
bazel test --config=linux ink/...
Ink consists of a set of modules that can be used separately. You should only need to include the parts of the library that you need. The basic dependency structure is:

color: Color spaces, encoding, and format conversion.types: Utility types; time, units, constants, small arrays.geometry: Geometric types (point, segment, triangle, rect, quad), meshes, transforms, utility functions, and algorithms (intersection, envelope).brush: Defines stroke styles and behaviors.strokes: The primary Stroke data type and InProgressStroke builder.rendering: Rendering utilities for strokes. Currently only has support for android.graphics.Mesh based rendering.storage: Protobuf serialization utilities for Stroke and related types.See CONTRIBUTING.md for details on sending a PR.
