|
|
|
|
SkiaSharp is a cross-platform 2D graphics API for .NET platforms based on Google's
|
|
Skia Graphics Library (https://skia.org/). It provides a comprehensive 2D API that can
|
|
be used across mobile, server and desktop models to render images.
|
|
|
|
## What is Included
|
|
|
|
SkiaSharp provides a PCL and platform-specific bindings for:
|
|
|
|
- Mac (Console or using the Xamarin.Mac)
|
|
- Xamarin.Android
|
|
- Xamarin.iOS
|
|
- Xamarin.tvOS
|
|
- Xamarin.Mac
|
|
- Windows Desktop (Windows.Forms / WPF)
|
|
- Windows UWP
|
|
|
|
You can also build this on your particular variant of Unix
|
|
to create your native libraries.
|
|
|
|
## Using SkiaSharp
|
|
|
|
SkiaSharp is available as a convenience NuGet package, to use install the package like this:
|
|
|
|
```
|
|
nuget install SkiaSharp
|
|
```
|
|
|
|
Our [getting started guide](https://developer.xamarin.com/guides/cross-platform/drawing/) will walk you
|
|
through both the basic setup as well as the platform specific capabilties.
|
|
|
|
The [API Documentation](https://developer.xamarin.com/api/namespace/SkiaSharp/) is also available on the
|
|
web to browse.
|
|
|
|
### Prerequisites
|
|
|
|
Make sure the [Microsoft Visual C++ 2015 Redistributable](https://www.microsoft.com/en-us/download/details.aspx?id=52982) is installed if this error occurs:
|
|
> Unable to load DLL 'libSkiaSharp.dll': The specified module could not be found.
|
|
|
|
## Building SkiaSharp
|
|
|
|
First clone the repository:
|
|
|
|
$ git clone https://github.com/mono/SkiaSharp.git
|
|
|
|
Next, set up the submodules:
|
|
|
|
$ cd SkiaSharp
|
|
$ git submodule init && git submodule update
|
|
|
|
Then follow the platform-specific instructions below.
|
|
|
|
### Mac OS X
|
|
|
|
Run from Bash
|
|
|
|
$ ./bootstrapper.sh -t libs
|
|
|
|
This runs the build process by using the `libs` build target.
|
|
|
|
### Windows
|
|
|
|
You need Python 2.7 in `PATH` environment variable. Then you can build it:
|
|
|
|
> .\bootstrapper.ps1 -Target libs
|
|
|
|
This runs the build process by using the `libs` build target.
|
|
|
|
### Build Targets
|
|
|
|
There are several targets available, you can specify the target as the argument to the `-t` command line
|
|
option in the bootstrapper script.
|
|
|
|
- `Everything` - builds everything for the current platform
|
|
- `externals` - builds all the native libraries
|
|
- [win] `externals-windows` - builds the native libraries for Windows
|
|
- [win] `externals-uwp` - builds the native libraries for Windows UWP
|
|
- [mac] `externals-osx` - builds the native libraries for Mac OS X
|
|
- [mac] `externals-ios` - builds the native libraries for iOS
|
|
- [mac] `externals-tvos` - builds the native libraries for tvOS
|
|
- [mac] `externals-andoid` - builds the native libraries for Android
|
|
- `libs` - builds all the managed libraries
|
|
- [win] `libs-windows` - builds the managed libraries that can be built on Windows
|
|
- [mac] `libs-osx` - builds the managed libraries that can be built on Mac OS X
|
|
- `tests` - builds and runs the tests
|
|
- `samples` - builds the samples available for the current platform
|
|
- `docs` - updates the mdoc files
|
|
- `nuget` - packages the libraries into a NuGet
|
|
- `clean` - cleans everything
|
|
- `clean-externals` - cleans externals only
|
|
- `clean-managed` - cleans managed libraries/samples only
|
|
