Merge SVGs to Raster Image file format Using C#

SVG is one of the most used vector image formats for website building and print graphics to achieve scalability. But sometimes, you need to merge SVG files and save them as one raster image. A raster image represents a two-dimensional grid of pixels; it may store data in uncompressed or compressed formats. Images are widely taken to transmit pictures over the network and display photos and graphics on web pages and cloud drive repositories. With Aspose.SVG for .NET API, you can merge SVG to Image programmatically. Powerful C# API helps you to combine SVG files quickly and in high quality.

C# code example to merge SVG to PNG

A high-speed C# library allows .NET developers to merge SVG files and convert the combined result into other popular formats such as PDF, XPS, JPEG, PNG, BMP, GIF, and TIFF quickly and efficiently. You can combine multiple SVG files into a single file of another format at the same time and improve performance for tasks such as resource management, optimizing the number of HTTP requests, reducing the loading time of web applications, etc. Documents merging can be done with a few lines of code:

Merge SVG to PNG – C#

// Initialize SVG documents from files to merge 
using (var document1 = new SVGDocument("document1.svg"))
using (var document2 = new SVGDocument("document2.svg"))
using (var document3 = new SVGDocument("document3.svg"))
    // Create an instance of SvgRenderer
    using var renderer = new Aspose.Svg.Rendering.SvgRenderer();
    // Create an instance of ImageDevice
    using var device = new Aspose.Svg.Rendering.Image.ImageDevice("result.png");
    // Merge SVG to PNG
    renderer.Render(device, document1, document2, document3);

Steps to Merge SVG to Image using C#

  1. Load SVG documents using one of the SVGDocument() constructors.
  2. Create a new instance of the SvgRenderer class.
  3. Use the ImageDevice() constructor to initialize a new instance of the ImageDevice class.
  4. Call the Render() method to merge several SVGs into the required image format.
  5. Multiple SVG files will be saved to the raster image file on the specified path.

In the C# example above, the output format is PNG, as indicated by the use of ImageDevice and choosing a .png file extension. If you want to change the output format, you will need to use a different device class that matches the desired format. For example, you can use PdfDevice for PDF format. Additionally, you will need to provide the appropriate file extension in the output file path.
