SvgImageSource | Custom ImageSource that will become | Form library

I guess that you are using this Plugin

There is an Issue saying that they don't support UWP

Nevertheless it also looks like you could try and use it from your PCL project.In that case, don't forget to innit the library SvgImageSource.RegisterAssembly();

Why SvgImageSource Image, looks blurry than BitmapImage in UWP?

Please edit svg content with VS, and update the height and width property as auto like following.

I got the same result, here is my workaround for svg image in the tabbed bar.

For android, please visit this page https://shapeshifter.design/

Then import your SVG file to the website, then download the xml file, like following operation(click Import, select svg, choose the svg file, then select Export, Vector the drawable, download the xml file). Copy the xml file to the Android Resource/ Drawable folder(please check the build Action is AndroidResource of xml file). Note: if you want to change the line color of svg file, please open the xml, fond the fill color, change it.

Then you can use it in the pcl XML like following code.

For testing your code, I found memoryStream parameter is output type, but you send empty MemoryStream to the method. So, please try to modify WriteTo to Save method that could make sure memoryStream has content. I post the complete GetSourceAsync below, and you could use it directly.

I'm afraid text svg element is not supported in UWP platform. Please check SVG Support the text element is not in the support list. currently there is a workaround is convert the text to path element, and it will work.
