Null Reference When Drawing an SVG USE Element

[jamescauwelier]

I have a similar issue as well:

NullReferenceException: Object reference not set to an instance of an object Svg.SvgElementIdManager.GetElementById (System.Uri uri) (at C:/Dev/vvvv/SVG/Source/SvgElementIdManager.cs:44) Svg.SvgUse.Render (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/Document Structure/SvgUse.cs:77) Svg.SvgElement.RenderChildren (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/SvgElement.cs:726) Svg.SvgVisualElement.Render (ISvgRenderer renderer, Boolean renderFilter) (at C:/Dev/vvvv/SVG/Source/Basic Shapes/SvgVisualElement.cs:183) Svg.SvgVisualElement.Render (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/Basic Shapes/SvgVisualElement.cs:129) Svg.SvgElement.RenderChildren (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/SvgElement.cs:726) Svg.SvgVisualElement.Render (ISvgRenderer renderer, Boolean renderFilter) (at C:/Dev/vvvv/SVG/Source/Basic Shapes/SvgVisualElement.cs:183) Svg.SvgVisualElement.Render (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/Basic Shapes/SvgVisualElement.cs:129) Svg.SvgElement.RenderChildren (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/SvgElement.cs:726) Svg.SvgElement.Render (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/SvgElement.cs:714) Svg.SvgFragment.Render (ISvgRenderer renderer) (at C:/Dev/vvvv/SVG/Source/Document Structure/SvgFragment.cs:169) Svg.SvgDocument.Draw (System.Drawing.Bitmap bitmap) (at C:/Dev/vvvv/SVG/Source/SvgDocument.cs:496)

The SVG I am trying to draw is at http://pastebin.com/vGmvTSU8

Could somebody give me some pointers here? It all renders in several browsers. Interesting is that I am able to render in VisualStudio, but not when I use my DLL in Unity3D.

It'd be great if you could take a look @gregsn or if @rfoltz could explain whether it was ever solved for him?

Nevermind... Just discovered that System.Drawing is not available in Unity and I need to find an alternative way to render in Png or use a library that can visualize SVG in Unity. The latter approach gave me low quality results though, but we'll see what happens.

Looks like this is the same problem that will be fixed with #377.
