Simple introduction about Word XML

Word XML is a special XML format, which makes Word be able to manipulate the Word documents stored in XML format. It can be divided into two types: WordML(supported by Word 2003) and WordXML(supported by Word 2007). If external applications support Word XML and the generated data follow the Word XML structure, then the data can be processed by Word. In this way, Word XML has become the bridge between Word and other external applications, any XML- formatted document based on Word XML structure can be opened, edited and saved in Word.

It also offers support for converting Word and HTML to frequently-used image formats like Jpeg, Png, Gif, Bmp and Tiff, etc. Just click here to have a try.

Emf is a file extension for Enhanced MetaFile, used as a graphics language for printer drivers by the Windows operating system. In 1993, a newer version with additional commands 32-bit version of Win32/GDI introduced the Enhanced Metafile (Emf). Microsoft also recommends enhanced-format (Emf) functions to be used instead of rarely being used Windows-format (WMF) functions.

Spire.Doc presents almost the easiest solution to convert Word to Emf through the following 5 lines simple code.

using Spire.Doc;
using System.Drawing.Imaging;


namespace DOCEMF
{
    class Program
    {
        static void Main(string[] args)
        {
            // create an instance of Spire.Doc.Document
            Document doc = new Document();
            // load the file base on a specified file name
            doc.LoadFromFile(@"../../Original Word.docx", FileFormat.Docx);
            //convert the first page of document to image
            System.Drawing.Image image = doc.SaveToImages(0, Spire.Doc.Documents.ImageType.Metafile);
            // save the document object to Emf file
            image.Save(@"../../Convert Word to Image.emf", ImageFormat.Emf);
            //close the document
            doc.Close();

        }
    }
}
