使用SkiaSharp在Xamarin中加载SVG文件 [英] Load SVG file in Xamarin with SkiaSharp

问题描述

从1.55.0版开始，SkiaSharp支持读取SVG文件. 该软件包已于几天前(2016年11月10日)发布，我找不到足够的文档来了解如何使用它.

From release 1.55.0 SkiaSharp has the support for reading SVG files. The package has been release few days ago (10 Nov. 2016) and I couldn't find enough documentation on how to use it.

以下软件包是必需的: SkiaSharp 1.55.0 SkiaSharp Views& 1.55.0层 SkiaSharp.Svg 1.55.0-beta1

The following packages are required: SkiaSharp 1.55.0 SkiaSharp Views & Layers 1.55.0 SkiaSharp.Svg 1.55.0-beta1

第一个问题是在Xamarin.Android中加载SKSvg的最佳方法是什么?

The first question is what's the best way to load an SKSvg in Xamarin.Android?

推荐答案

以下两种开始与SkiaSharp合作的可能对我有用的解决方案:

Here two possible solutions to start working with SkiaSharp that are working for me:

从Asset文件夹(或子文件夹)加载SVG:

public SKSvg LoadAnSvgFromAssets(Context ctx, string assetSvgFileLoc)
    {
        var assets = ctx.Assets;
        var svg = new SKSvg();
        using (var stream = new StreamReader(assets.Open(assetSvgFileLoc)))
            {
              svg.Load(stream.BaseStream);
              return svg;
            }
    }

其中"assetSvgFileLoc"是要加载的svgFilename.svg，包括(如果是)包括Asset文件夹内的路径(例如"subf1/subf2/mysvg.svg").

where "assetSvgFileLoc" is the svgFilename.svg to load, including (if it's the case) the path inside Asset folder (e.g. "subf1/subf2/mysvg.svg").

将SVG加载为RAW资源

public SKSvg LoadAnSvgFromResources(Context ctx, string svgName))
  {
    var resId = ctx.Resources.GetIdentifier(svgName, "raw", ctx.PackageName);           
    var svg = new SKSvg();
    using (var stream = ctx.Resources.OpenRawResource(resId))
    {
        svg.Load(stream);
        return svg;
    }
}

在这种情况下，文件位于Resources子文件夹"raw"内，而"svgName"是我们svg的文件名，不带扩展名.

In this case the file is inside the Resources subfolder "raw" and the "svgName" is the filename of our svg without extension.
