Question

watermark opacity does not work

Hi,

We are using the Adobe InDesign CC Server 2014, and calling its functionality via scripts. One feature, what we have to use is adding watermark to every page and generate PDFs with watermark.

Watermark must be in the middle of the every page and displaywed with 50% opcaity.

We trying to achive it with the attached code below.

Sadly opacity setting is ignored. What we are doing badly?

Positioning to the middle is not really working either.

myDocument.watermarkPreferences.watermarkHorizontalPosition = WatermarkHorizontalPositionEnum.WATERMARK_H_CENTER;

This kind of setting not seems to be working, so we used the

myDocument.watermarkPreferences.watermarkHorizontalOffset = 20;

which is working, but not really what we needed.

Regards

Balázs

I have a bad feeling....

So when I wrote my first question I tried to make a watermark on a document with one page and opacity never worked.

Now I tested it with an another 4 pages document, and got a big supprise. On the first page, the watermark opcaity used, but on remaining pages still not.

I gave the script code in my first question. Can anybody help me to figure our what happening? What kind of settings has to be done in the script in order to display watermark with opacity in every page independently from page number, etc.

PLS HELP
