C# .svg file to System.Drawing.Image

Question

I need to convert the selected .svg file to System.Drawing.Image object, so I can resize it and save it as .png. Can anyone help me with this?

Here is what I have so far:

Svg.SvgDocument svgDocument = SVGParser.GetSvgDocument(mPath);
image = svgDocument.Draw();

But it gives me out of memory error.

How should i use SVGParser ? is there any nuget ?? – Compress

Answer 1

So,

SVGParser.MaximumSize = new System.Drawing.Size(4000, 4000);
svgDocument = SVGParser.GetSvgDocument(mPath);
var bitmap = svgDocument.Draw();
image = bitmap;

You should place a link to the library you are using on the example because without it the answer is quite useless – Stardom

He used a package called svg. To install it simply run the following in the package manager: Install-Package Svg – Persuasive

Answer 2

You can use the SVG Rendering Engine Lib:

Install-Package Svg

It's quite easy to draw images using it:

var svgDoc = SvgDocument.Open(imagePath);

using(var Image = new Bitmap(svgDoc.Draw()))
{
    Image.Save(context.Response.OutputStream, ImageFormat.Png);
    context.Response.ContentType = "image/png";
    context.Response.Cache.SetCacheability(HttpCacheability.Public);
    context.Response.Cache.SetExpires(DateTime.Now.AddMonths(1));
}

In this example i'm using a handler to display the image on the browser but you can easily save it on some folder just by changing the first parameter of the Save method.

How do you get this to work in a loop and not trash the 2nd and subsequent images? Do you know? – Lordan

@Lordan what do you mean by trash the 2nd ? You could try to put the svgDoc into an using like the Image – Stardom

what is context in your example? it's not declared – Rempe

@Rempe the context is the HttpContext, i'm using this inside a handler, so the context is given as a parameter on the ProcessRequest method – Stardom

The resource Miljan Vulovic used is svg (https://archive.codeplex.com/?p=svg).

Link is only valid until July 2021, it might be available on GitHub by then, but I'm not sure.

Anyways his solution works for me.
