# alphaSkia

alphaSkia is a special cross platform [Skia](https://skia.org/) wrapper used in [alphaTab](https://github.com/CoderLine/alphaTab) it aims to provide a HTML5 Canvas like API to alphaTab providing a consistent rendering experience across the alphaTab flavours like web, .net and Kotlin. Differences across operating systems might still apply.

## Versioning 

alphaSkia a slightly adapted [Semantic Versioning](https://semver.org/) scheme where the `PATCH` part indicates

the Skia milestone version we have integrated. 

Currently we are on [Skia m120](https://github.com/CoderLine/alphaSkia/blob/main/.gitmodules#L8)

Given a version number `MAJOR.MINOR.SKIA`:

1. `MAJOR` is incremented when we make incompatible API changes. 

2. `MINOR` is incremented when we add functionality in a backward compatible manner

3. `SKIA` is aligned with the Skia milestone we have integrated. See [here](https://skia.org/docs/user/release/#release-process) and [here](https://chromiumdash.appspot.com/schedule)

The prerelease labels and tags we use: 

* Pre-Release versions for builds which are in-development

    * SemVer: `-alpha.` (NuGet and NPM)

    * NPM Tag: `alpha`

    * Maven: `-SNAPSHOT`

* Local Builds (not published anywhere)

    * SemVer: `-local`

    * Maven: `-LOCAL`
