Problem trying to render SVG objects (Open() method)

Description

In a C# project I’m trying to convert from SVG to Image object using the following code: img = Svg.SvgDocument.Open(filePath).Draw();

The problem is with the ‘Open’ method since I divided that line into Open first and Draw after it.

And it does not fail but the svg is not being rendered correctly. I also have these traceback errors: HCTgui.exe Warning: 0 : Attribute ‘width’ cannot be set - type ‘Svg.SvgDocument’ cannot convert from string ‘29.724014mm’.

Example data

It happens with any single .SVG I try to use. All of them correctly validated and working.

Used Versions

I’m using Visual Studio 2019 Pro, Windows 10 and SVG 3.3.0

Thank you so much!

Thank you very much! I’m not very experienced in using Visual Studio. It’s quite possible that the error is caused by an environment issue. I have run the SVGViewer from GitHub in a separate .net 5.0 solution, where everything worked well. The error occurred in a .NET Framework 4.8 project where the SVG.net DLL from NuGet is referenced. I’m not familiar enough with Visual Studio to assess, if this could be a reason or how to test it.

I will try to find out more…

• Ok, I also found a “manifest definition does not match the Assembly reference” error. I hate errors like that, as they are very confusing. I try this solution. --> No
• <package> targetFramework of SVG is net48. Cannot set it to net5.0 --> No

Edit: Quit sure, that this is an execution environment issue. It works with every new project I tried, but not in my actual solution. So thank you for your time and investigations. I have to find the bug by myself.

I created the following simple console app and get SVG.NET library from NuGet.

using System.IO;
using Svg;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var rootPath = @"<PATH_TO_ROOT_DIRECTORY>";
            var svgPath = Path.Combine(rootPath, "Image.svg");
            var imagePath = Path.Combine(rootPath, "Image.png");
            using (var image = SvgDocument.Open(svgPath).Draw())
            {
                image.Save(imagePath);
            }
        }
    }
}

Result was output correctly. (3.3.0 - 3.2.1).
