Convert VSDX to PNG

Files with .VSDX extension represents Microsoft Visio file format introduced from Microsoft Office 2013 onwards. It was developed to replace the binary file format, .VSD, which is supported by earlier versions of Microsoft Visio. It is also supported on Visio Services in Microsoft SharePoint Server 2013 and does not require an intermediary file format for publishing to SharePoint Server.

Steps to convert VSDX to PNG in C#

GroupDocs.Conversion allows developers to convert the VSDX file to PNG format in an easy and intuitive way just using a few lines of code as described below:

  • Create an instance of Converter class and pass source VSDX file path as a constructor parameter. You may specify absolute or relative file path as per your requirements.
  • Declare SavePageStream delegate, which should provide a stream to store converted page of VSDX document.
  • Create an instance of ImageConvertOptions class and set Format property to GroupDocs.Conversion.FileTypes.ImageFileType.Png.
  • Call Converter class Convert method and pass the filename for the converted PNG file and the ImageConvertOptions object from the previous step as parameters.
// Load the source VSDX file
using (Converter converter = new Converter("sample.vsdx"))
{
    string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.png");
    GroupDocs.Conversion.Contracts.SavePageStream getPageStream = page => new FileStream(string.Format(outputFileTemplate, page), FileMode.Create);

    // Set the convert options for PNG format
    var options = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Png };   
    // Convert to PNG format
    converter.Convert(getPageStream, options);
