Place static stamp with javascript

Question

We are placing static stamps on several pdf files and I would like to automate this. I am looking into javascript and trying to figure out how to set up a code. I would like a code to take a stamp named "Draft" and place it 50 mm from bottom and 50 mm from right.

I have tried to use add watermark and use the stamp as source file (and apply to multiple files) but it is not as easy to move the watermark, if necessary (for example if it is placed over something else). If the source file is added as a stamp and then the stamp is placed on the drawing it is much easier to just grab and move the stamp around.

A Stamp is an annotation (AKA "comment") so you can add it using the addAnnot method.

In order to do that you need to know a couple of things:

- The internal AP value of the stamp (its "name")

- The exact coordinates where you want to place it.

The best way to get both things is to manually apply it, and then select it with the mouse and execute the following code from the JS Console:

console.println(this.selectedAnnots[0].AP);

console.println(this.selectedAnnots[0].rect);

The output will be something like this:

SBDraft
18.898635864257812,228.94615173339844,132.0421905517578,278.6942138671875

You can use that to write your code. For example, this will add this stamp at that location to the first page of the file:

this.addAnnot({page: 0, type: "Stamp", AP: "SBDraft", rect: [18.898635864257812,228.94615173339844,132.0421905517578,278.6942138671875]});

You can use this code in an Action to process multiple files in a batch process.
