SVG support

SVG support

SVG files are now working and support every FFImageLoading's feature. It uses SkiaSharp for rendering.

Xamarin.Forms

It's very easy, just add Xamarin.FFImageLoading.Svg.Forms nuget and use SvgCachedImage instead CachedImage:

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="FFImageLoading.Forms.Sample.SvgSamplePage"
		xmlns:ffimageloadingsvg="clr-namespace:FFImageLoading.Svg.Forms;assembly=FFImageLoading.Svg.Forms">

	<ContentPage.Content>
		<ffimageloadingsvg:SvgCachedImage WidthRequest="200" HeightRequest="200" Source="sample.svg"/>	
	</ContentPage.Content>
</ContentPage>

More advanced scenarios: use a custom SvgImageSource which enables SVG support. Please notice, that it has optional parameters for controlling renderered SVG size (automatic by default) IMPORTANT: Your projects also must reference System.Xml.Linq.

From code:

source = SvgImageSource.FromFile("image.svg")
source = SvgImageSource.FromUri("http://example.com/image.svg")
// etc...

Or use a provided converter (eg. when using XAML):

Source="{Binding SvgFileName, Converter={StaticResource SvgImageSourceConverter}}"

Native

When loading images you have to configure custom data resolver which enables SVG support:

ImageService.Instance
			.LoadFile("image.svg")
			.LoadingPlaceholder("placeholder.svg")
			.WithCustomDataResolver(new SvgDataResolver(200, 0, true))
			.WithCustomLoadingPlaceholderDataResolver(new SvgDataResolver(200, 0, true))
			.Into(imageView);

You can also load svg image from string:

	var svgString = @"<svg><rect width=""30"" height=""30"" style=""fill:blue"" /></svg>";

	ImageService.Instance
		.LoadStream(ct => Task.FromResult<Stream>(new MemoryStream(Encoding.Default.GetBytes(svgString))))
		.LoadingPlaceholder(placeHolderPath)
		.WithCustomDataResolver(new SvgDataResolver(64, 0, true))
		.WithCustomLoadingPlaceholderDataResolver(new SvgDataResolver(64, 0, true))
		.Into(imageView);

Converting svg string into UIImage:

	var svgString = @"<svg><rect width=""30"" height=""30"" style=""fill:blue"" /></svg>";

	UIImage img = await ImageService.Instance
		.LoadStream(ct => Task.FromResult<Stream>(new MemoryStream(Encoding.Default.GetBytes(svgString))))
		.WithCustomDataResolver(new SvgDataResolver(64, 0, true))
		.AsUIImageAsync();
