Stamps and Layers

[rkanther]

What i want:
I would like to create a stamp where the user can decide whether it is transparent or not.

My idea:
The finished stamp has already a dynamic date field which offers the possibility to change the format via user form. In addition, I would like to insert a white rectangle on a new layer ("BG") in the background and then control it via script.

Is it even possible to control the layer (on/ off) after placing and before inserting the stamp?

Hello rkanther,

Wouldn't it be much easier if you just have two variants of the stamp - one with and one without the transparent background that you plan to add? Doing it via JS might be possible however I do not think you can control the visibility of non field elements of a dynamic stamp - so it would really be much simpler if you just have two versions of the stamp.

Kind regards,
Stefan

Hello Stefan,

It is certainly easier for one stamp at the moment. At the moment it was only a technical consideration whether it would work at all. If you have a lot of stamps and have to keep two variants for everything, it becomes confusing and no longer maintainable.

Hello, rkanther

You can certainly try, but as Stefan said, I am unsure if this is possible to accomplish with the JS access stamps have. You can learn more about using JS in PDF context here: https://opensource.adobe.com/dc-acrobat ... croJS.html

Kind regards,

Take a look at the examples with the library I posted here:
viewtopic.php?t=45879

If you put annotations into the stamp, you can change their properties (ie transparency of a rectangle) during the stamp script.

The stamps in this example change the opacity of a background mask: viewtopic.php?p=192281#p192281

Thanks for the input, Mathew.

Thanks Mathew. I'll test it!
