Convert DOTM to PNG

A file with DOTM extension represents template file created with Microsoft Word 2007 or higher. It is similar to the popular DOCX file format other than it retains the user defined settings for reuse in case of creating new documents. Such documents are more often used in offices where a standard template file is generated with settings like page information, margins, default layout and macros, and is used to create new documents from it when required. DOTM files, however, save macros, that are a series of commands in the form of recorded actions for automatic completion of a task. This helps save time in carrying out actions that are repeated in completion of a task.

Steps to convert DOTM to PNG in C#

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