Creating watermark programatically

[sunny8875]

Hi,

I am trying to generate a .docx document programatically, Can any one please let me know how to add watermark(say for example a draft watermark) to the document that is being created programatically.

Thanks in advance.

[jason]

As usual, create a sample docx and upload it to the webapp to generate code.

IIRC, the watermark is place in the header, so be sure to look at those.

Hi,

i used some sample code to add an image to the header... it worked

But i have one problem which i couldn't solve => the image is in the text flow, so everything is moving if the picture is too big. I want that the picture is behind the text... but i didn't find any solution to do this.

And where can i find this webapp to generate code?

Thank you for your help.

Best regards

[jason]

Präfix "wp" für Element "wp:anchor" ist nicht gebunden.

Declare the namespace in your string

public static Relationship nextTest(WordprocessingMLPackage wordMLPackage, byte[] image) throws Exception {

HeaderPart headerPart = new HeaderPart();

You still need to add headerPart to wordMLPackage; see the relevant sample (ie in src/samples on GitHub).

[AndreasN]

Hi,

I tested the watermark example with a docx template which has already a headerpart.

https://github.com/plutext/docx4j/blob/master/src/samples/docx4j/org/docx4j/samples/Watermark.java


As there was no text visible of the watermark in the processed template file, I played around with some settings, especially the type of the created headerReference object and got it nearly:

Code: Select all

HeaderReference headerReference = factory.createHeaderReference();
headerReference.setId(relationship.getId());
headerReference.setType(HdrFtrRef.FIRST);

The problem now is that the document headers margin / position shifts down for 20-30 px.

Maybe the already existing SectionWrapper properties (SectPr) and within the existing headerreferences (sectPr.getEGHdrFtrReferences()) needs to be changed in some way?


Second item of interest: How to bring the watermark in front of all body content?

I changed the XML a bit and the background text is now partially shown in front of existing table objects in the processed template - but unfortunately not in front of filled table cells in that tables.

Code: Select all

<v:shape fillcolor=\"red\" id=\"PowerPlusWaterMarkObject357476642\" o:allowincell=\"f\" o:spid=\"_x0000_s2049\" stroked=\"f\" style=\"position:absolute;margin-left:0;margin-top:0;width:527.85pt;height:131.95pt;rotation:315;z-index:0;mso-position-horizontal:center;mso-position-horizontal-relative:margin;mso-position-vertical:top;mso-position-vertical-relative:margin\" type=\"#_x0000_t136\">" + "<v:fill opacity=\".6\"/>

Kind regards,
Andreas

One way to proceed is to open your generated docx in Word and edit it to suit using Word.

Then you examine the resulting XML to determine what you need to set in your docx4j code.

If you can't tell what you need to change or how to change it, feel free to post your generated docx and the desired-state docx.

Hi,

I updated the example and add an attachment to illustrate how it works with an already given header.

The tiny offset of the headline after adding the watermark is ok to me, there will be a break added in the content area, don't know why.

The overlay of the body content, especially with shaded table cells, is probably the nature of the different areas / layers and can't be manipulated (so far I read the specs and reviewed the existing properties) - http://officeopenxml.com/WPtableCellPro ... hading.php

@Jason: I used your great analysis tool "Docx4j Helper for Word" - thx again for contributing.

Kind regards,
Andreas

Hi,

I did some minor changes to my contributed example class:
- the watermark is now rendered on all document pages
- there is a quantifier to define the number of repeats on each page

For the non-word conform watermark hack in front of all, there is an approach to put the text / image into a table in the first row and make this as head row; in principle it works but I failed when the document has more than one page as I guess the page breaks needs to be considered.

Jason, thank you for support.

Kind regards,
Andreas

Hi,

I updated the watermark example to get rid of existing header references of type FIRST, before I create a new header reference... I noticed in one use case I have that headers got doubled when documents are merged; maybe if first document header differs might probably have an impact too.

It's experimental code, maybe someone find it useful.

Kind regards,
Andreas

Hi,

Finally I implement a solution which works as expected. The only requirement on the document is that a header part exists.

Cheers,
Andreas
