Water mark test is stretching unnecessarily in pdf file

Hi Aspose,
I am confronting a weird issue after generating a pdf document with the help of Aspose.Words API. My requirement is, I need to insert three lines watermark text in footer for which i have created three water marks with text, fixed there positions from top of the document and inserted them into footer. By following this approach .docx document is generating without any issue but when i try to produce .pdf document, third line which has less text compared to other two lines stretches to fill the complete width of the other water mark texts which is an issue. Please help

I am attaching complete code which i have followed from Add Watermark in C#|Aspose.Words for .NET article.

Produced Sample.docx snapshot document which seems perfect
Sample.zip (11.5 KB)

Produced Sample.pdf snapshot document (notice third line)

Below is the complete code based on Add Watermark in C#|Aspose.Words for .NET article.

class Program
{
static void Main(string[] args)
{
var path = @“D:\Sample.docx”;
var pathToGenerateDoc = @“D:\Watermark\Sample.docx”;
var pathToGeneratepdf = @“D:\Watermark\Sample.pdf”;
Document doc = new Document(path);
double top = 765D;

        string copyRightText =  "Copyright © 2018 by the Aspose.Words company of Word and pdfs. Warning: This particular document is protected by U.S. with Copyright Law and International Treaties.";

        string thirdline = "project.";

@mehtabcompunnel,

Thanks for your patience. It is to inform you that the issue which you are facing is actually not a bug in Aspose.Words. So, we have closed this issue (WORDSNET-16823) as ‘Not a Bug’.

Please note that Word for Mac has some difficulties with VML shapes, so in order to create correct output for Mac Word, please change ShapeType.TextPlainText to ShapeType.TextBox in your code. Please check the following code example.

Document doc = new Document();
double top = 760D;
string copyRightText = "Copyright © 2018 by the Aspose.Words company of Word and pdfs. Warning: This particular document is protected by U.S. with Copyright Law and International Treaties.";
string secondline = "It was created by \"Firm-MAli\" for \"Header Regression Test\".  I must test Aspose.word feasiblity of generating documents before purchasing any license Please Do.";
string thirdline = "project.";
ApplyWaterMark(doc, copyRightText, top);
top = top + 8D;
ApplyWaterMark(doc, secondline, top);
top = top + 8D;
ApplyWaterMark(doc, thirdline, top);
OoxmlSaveOptions saveOptions = new OoxmlSaveOptions(SaveFormat.Docx);
saveOptions.Compliance = OoxmlCompliance.Iso29500_2008_Strict;
doc.Save(MyDir + "18.5.docx", saveOptions);

public static void ApplyWaterMark(Document doc, string watermarkText, double top)
{
    Run text = new Run(doc, watermarkText);
    text.Font.Size = 7;
    text.Font.Name = "Calibri";
    text.Font.NoProofing = true;

    Paragraph watermarkTextPara = new Paragraph(doc);
    watermarkTextPara.AppendChild(text);

    Shape watermark = new Shape(doc, ShapeType.TextBox);
    watermark.RelativeVerticalPosition = RelativeVerticalPosition.Page;
    watermark.Width = 500;
    watermark.Height = 10;
    watermark.Top = top;
    watermark.TextBox.InternalMarginBottom = 0;
    watermark.TextBox.InternalMarginTop = 0;
    watermark.TextBox.InternalMarginLeft = 0;
    watermark.Stroked = false;
    watermark.WrapType = WrapType.None;
    watermark.AppendChild(watermarkTextPara);

    Paragraph watermarkPara = new Paragraph(doc);
    watermarkPara.AppendChild(watermark);

    foreach (Section sect in doc.Sections)
    {
        // There could be up to three different headers in each section, since we want
        // the watermark to appear on all pages, insert into all headers.
        insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.FooterPrimary);
        insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.FooterFirst);
        insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.FooterEven);
    }
}

public static void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, HeaderFooterType headerType)
{
    HeaderFooter header = sect.HeadersFooters[headerType];
    if (header == null)
    {
        header = new HeaderFooter(sect.Document, headerType);
        sect.HeadersFooters.Add(header);
    }
    header.AppendChild(watermarkPara.Clone(true));
}

Thanks @tahir.manzoor, ShapeType.TextBox approach instead of ShapeType.TextPlainText resolved the stretching as well as copyright symbol © not visible issue in watermark issue.
Thanks a ton!!!

@mehtabcompunnel,

Thanks for your feedback. We have closed this issue (WORDSNET-16823) as “Not a Bug”.

@mehtabcompunnel,

By using ShapeType.TextBox in the code also resolves WORDSNET-16816 (Watermark text is stretched in output PDF). Please confirm. We will then close this issue.

@tahir.manzoor, Yes, It has been resolved. I am highly obliged for your cooperation. :+1:t3:
