Rendering SVG as PNG

Let’s start with a practical example of rendering an SVG document as a PNG image.

string dataDir = "Your Data Directory";
using (var document = new Aspose.Html.Dom.Svg.SVGDocument("<svg xmlns='http://www.w3.org/2000/svg'><circle cx='50' cy='50' r='40'/></svg>", @"c:\work\"))
{
    using (SvgRenderer renderer = new SvgRenderer())
    using (ImageDevice device = new ImageDevice(dataDir + @"document_out.png"))
    {
        renderer.Render(device, document);
    }
}

Explanation:

  1. We specify the data directory where the output image will be saved.

  2. We create an instance of SVGDocument by providing the SVG content and the base URI.

  3. Next, we use SvgRenderer and ImageDevice to render the SVG document as a PNG image.

  4. The resulting PNG image is saved in the specified data directory.

This example showcases how Aspose.HTML for .NET can simplify complex tasks like SVG to PNG conversion. You can apply similar principles to various HTML-related operations.
