Convert DOT to PNG

Files with .DOT extension are template files created by Microsoft Word to have pre-formatted settings for generation of further DOC or DOCX files. A template file is created in order to have specific user settings that should be applied to subsequent files created from these. These settings include page margins, borders, headers, footers, and other page settings. Such templates are used in official documents such as company letterheads and standardized forms.

Steps to convert DOT to PNG in C#

GroupDocs.Conversion allows developers to convert the DOT 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 DOT 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 DOT 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 DOT file
using (Converter converter = new Converter("sample.dot"))
{
    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);
}
