Watermark washout property

Aspose.Words Product Family
1

Hi, we are using c-sharp to insert watermarks into templates. Some watermarks do not show up on the templates and upon investigation I have found that the ‘Washout’ property has been checked.
I would like to know if there is a way to set the property to unchecked using c-sharp?
Thanks,
Aaron

Hi Aaron,

Thanks for your inquiry. We will consider adding appropriate properties in our API to be able to enable/disable Sepia and Washout color modes for images. I have logged a new feature request in our bug tracking system. The issue ID is WORDSNET-7103. Your request has been linked to this feature and you will be notified as soon as it is available. Sorry for the inconvenience.

Hi,
I’ve attached a vs2005 solution with examples of “working and not working” watermarks.

Hi Aaron,

Thanks for your inquiry. There are many DrawingML nodes inside different headers/footers in your watermark documents (the documents you’re using as watermark for example ‘NotWorking.docx’). I would suggest you first convert this whole document to an image format e.g. PNG and then generate a clean intermediate document by placing this PNG at the first header. You can then finally copy the contents of the headers/footers from this document into your template document as follows:

Document doc = new Document(@"C:\Temp\notworking.doc");
// Save document to an Image format
MemoryStream imgStream = new MemoryStream();
doc.Save(imgStream, SaveFormat.Png);
// Load this Image and place it in first header
Document docB = new Document();
using(Image img = Image.FromStream(imgStream))
{
    double pageWidth = doc.Sections[0].PageSetup.PageWidth;
    double pageHeight = doc.Sections[0].PageSetup.PageHeight;
    docB.Sections[0].PageSetup.PageWidth = pageWidth;
    docB.Sections[0].PageSetup.PageHeight = pageHeight;
    DocumentBuilder builder = new DocumentBuilder(docB);
    builder.MoveToHeaderFooter(HeaderFooterType.HeaderFirst);
    Shape watermark = builder.InsertImage(img);
    if (img.Width > pageWidth)
        watermark.Width = pageWidth;
    else
        watermark.Width = img.Width - 50;
    if (img.Height > pageHeight)
        watermark.Height = pageHeight;
    else
        watermark.Height = img.Height - 50;
    watermark.RelativeHorizontalPosition = Aspose.Words.Drawing.RelativeHorizontalPosition.Page;
    watermark.RelativeVerticalPosition = Aspose.Words.Drawing.RelativeVerticalPosition.Page;
    watermark.WrapType = Aspose.Words.Drawing.WrapType.None;
    watermark.VerticalAlignment = Aspose.Words.Drawing.VerticalAlignment.Top;
}
// At this point clean watermark document is built
// Now merge the contents of the headers/footers
// in your template document and watermark document as follows
Document docA = new Document(@"C:\Temp\warn45.doc");
DocumentBuilder builderA = new DocumentBuilder(docA);
// Loop through all sections in the B document
foreach(Section sectB in docB.Sections)
{
    Section sectA = null;
    int sectBIndex = docB.Sections.IndexOf(sectB);
    // Check whether document A conteins section with same index
    if (docA.Sections.Count > sectBIndex)
    {
        // Get correcponding section
        sectA = docA.Sections[sectBIndex];
    }
    else
    {
        // Insert empty section
        builderA.MoveToDocumentEnd();
        builderA.InsertBreak(BreakType.SectionBreakContinuous);
        sectA = builderA.CurrentSection;
    }
    // Loop throught all Headers/Footers in the B document
    foreach(HeaderFooter hfB in sectB.HeadersFooters)
    {
        // Check whether current section from docA conteins
        // Header/Footer with the same type as h/f from docB
        if (sectA.HeadersFooters[hfB.HeaderFooterType] != null)
        {
            // Append content from h/f B to h/f A
            foreach(Node childB in hfB.ChildNodes)
            {
                // Import node
                Node childA = docA.ImportNode(childB, true, ImportFormatMode.KeepSourceFormatting);
                // Appent node to h/f
                sectA.HeadersFooters[hfB.HeaderFooterType].AppendChild(childA);
            }
        }
        else
        {
            // Copy whole h/f
            Node hfA = docA.ImportNode(hfB, true, ImportFormatMode.KeepSourceFormatting);
            // Insert h/f
            sectA.HeadersFooters.Add(hfA);
        }
    }
}
// Save output document
docA.Save(@"C:\Temp\finalout.doc");

I hope, this helps.
