mnuthan,

Can you post your code? It may be interesting to see how you have done it, and then we can enhance your solution further.

I am not sure how to use watermark property ,

Edit: Hagar: added the BBCode tags for the code for a better readability.

I wanted to add watermark and header/footer to the PDF file. Can some one please tell me what filteroptions will add watermark and header/footer in PDF file

As far as I know, it is not possible to do this by adding some PDF filter settings. What you can do is after loading the .doc file add a watermark and a header and footer to the document and export that file as a PDF. You can find more on working with text documents in the OOo Developer's Guide: http://api.openoffice.org/docs/Develope ... _Documents

Hi ,
Thanks for your reply, I have checked documentation and it seems there is no direct way to add watermark to a document. Can you please give example code to add watermark to document.

[hol.sten]

Can you please give example code to add watermark to document.

No, because I have none. But I can tell you, that you can add a watermark to a document by setting a background graphic for the PageStyle (com.sun.star.style.PageStyle, com.sun.star.style.PageProperties => BackGraphicURL) of the document: http://api.openoffice.org/docs/Develope ... age_Layout

[bprateek28]

You can add watermark using the following property

Code: Select all

PropertyValue[] filterProps = (PropertyValue[]) java.lang.reflect.Array.newInstance(PropertyValue.class, 1);
  filterProps[0] = new PropertyValue(); 
  filterProps[0].Name = "Watermark"; 
  filterProps[0].Value = "kota"; 

  //set up an array of PropertyValue objects used to save the document
  PropertyValue[] storeProps = new PropertyValue[3];
  storeProps[0] = new PropertyValue();
  storeProps[0].Name = "FilterName";
  storeProps[0].Value = "writer_pdf_Export";
  storeProps[1] = new PropertyValue();
  storeProps[1].Name = "Overwrite ";
  storeProps[1].Value = true;
  storeProps[2] = new PropertyValue();
  storeProps[2].Name = "FilterData";
  storeProps[2].Value = filterProps;
  xStorable.storeToURL(storeUrl, storeProps);

I have been able to come this far, haven't been able to handle the position on orientation of it.

Thanks,
Prateek.
