Slow creation of pdf document In case of image type "emz" inside xml document

Hi Team,

I am creating a pdf document from the xml document having “emz” as image type in it.
Below code took 30-40 seconds to create the pdf document. If i remove the image or insert it as a “png” then the document created within 1-2 seconds.

Dim doc As New Aspose.Words.Document(ms)

Please let me know if we can improve the pdf creation.

Hi Tahir,

Thank you for the reply. Can we use ASPOSE.NET to convert emz bindata inside the XML file to png data ?


Please use following code example to convert EMZ to PNG in the document. Hope this helps you.

var document = new Document(MyDir + @"Call Invoice v3.xml");
DocumentBuilder builder = new DocumentBuilder(document);
foreach (Shape shape in document.GetChildNodes(NodeType.Shape, true))
    if (shape.HasImage)
        MemoryStream stream = new MemoryStream();
        shape.GetShapeRenderer().Save(stream, new ImageSaveOptions(SaveFormat.Png));
document.Save(MyDir + "21.7.xml", SaveFormat.WordML);
