Image watermarks and image text wrapping

[fatmedia]

hi there, could you please tell me the best ways to do the followng using spire.doc:

1) Add an image watermark
I have tried to do this using the Spire.Doc.PictureWatermark but the image doesnt show (or it does sometimes work but then flickers and disappears after a few seconds)

2) add an image to the top right of every page and set the text wrapping to behind the text

3) add a full page sized image to every page and set the text wrapping to in-front of the text


all three of these are being saved/streamed to PDF files.


any help would be greatly appreciated!


thank you.

Hello fatmedia,

Thanks for your inquiry and sorry for the late reply.

We have tested the first issue you said with the latest hotfix[Spire.Doc v4.1.22] using the following code:

Code: Select all

//load the document
            Document doc = new Document();
            doc.LoadFromFile(@"..\..\test.doc", FileFormat.Doc);

            //load the picture
            Image image = Image.FromFile(@"..\..\untitled.bmp");

            //new a pictureWatermark using the picture
            PictureWatermark picMark = new PictureWatermark(image, false);

            //insert the pictureWatermark into the document
            doc.Sections[0].Document.Watermark = picMark;
     
            //save the document as PDF file
            doc.SaveToFile(@"..\..\result.pdf", FileFormat.PDF);
 

. It works fine. Would you please have a kind try with the hotfix,you can download it at http://www.e-iceblue.com/Download/download-word-for-net-now/spire-doc-hv4122.html.

For the second question,you can use the following code:

Code: Select all

//load the document
            Document doc = new Document();
            doc.LoadFromFile(@"..\..\test.doc", FileFormat.Doc);

            //create a header
            HeaderFooter header = doc.Sections[0].HeadersFooters.Header;

            //insert picture to header
            Paragraph headerParagraph = header.AddParagraph();
            DocPicture headerPicture
            = headerParagraph.AppendPicture(Image.FromFile(@"..\..\header.jpg"));

            //set the textWrapStyle
            headerPicture.TextWrappingStyle = TextWrappingStyle.Behind;

            //allocate the picture
            headerPicture.VerticalAlignment = ShapeVerticalAlignment.Top;
            headerPicture.HorizontalAlignment = ShapeHorizontalAlignment.Right;

            //save the document
            doc.SaveToFile(@"..\..\result.pdf", FileFormat.PDF);

As the third question, Spire.Doc doesn't support to set the text wrapping to in-front of the text at present. We are so sorry for the inconvenience.

If you still have any other questions,please feel free to contact us.

Have a great day.
