Is it possible to remove watermarks programatically?

You will need to manipulate the "state" property of the "Watermark" OCG object.

function SetWatermarkState(doc, bState) {
/* set the "Watermark" to bState for doc
doc - doc objet to process
bState - value for logical state
true = show
false = hide
*/

var ocgArray = doc.getOCGs();
for (var i=0; i < ocgArray.length; i++) {
if (ocgArray[i].name == "Watermark") {
ocgArray[i].state = bState;
} // end if Watermark
} // end loop through the OCG object
return;
} // end SetWatermarkState function

SetWatermarkState(this, false);

Bear in mind the JS snippet above doesn't "remove" anything - it just sets it to invisible, so there may still be a downstream issue if the watermark contained something you really don't want to share!

Right. I want to remove it completely not just hide it. I wonder why I can add a watermark with JavaScript yet the menu item to remove it dosen't work. Unless maybe I'm leaving something out of the code below.

this.addWatermarkFromText({
cText: "DRAFT",
cFont: font.HelvB,
bOnTop: false,
nScale: -.8,
nRotation: 45,
nOpacity: .4
});

If I add another watermark using the UI so there are now two watermarks and select Document > Watermark > Remove and click Ok both watermarks are removed.

Have you read this:

There is no JavaScript method to remove a watermark, so you only have the abiltiy to change its state without any interaction. You could also execute the menu item to remove the watermark, but you will still have to deal with the conformation window. And then there is the redaction approach but you have to find, mark and apply.

I thought about trying to use execute menu item but I think Acrobat has made it harder to get to some of menu items. At least if I am looking at it right the number of menu items that are easy to get to have dwindled in number over the past two versions.

But. I it is a good suggestion and I will take a look at it. I would be ok with dealing with the confirmation window. In fact I'm Ok using the UI to work with watermarks it is just some of the other folks at work who have a hard time with multiple step operations that I have set up a custom tool bar button so all they have to do is click the button to put the DRAFT water mark on page.

I think there needs to be either a JS method to assist in removing a watermark or the UI recognize that there really is a watermark there.

Thanks everyone for helping out on this. I really do appreciate it.

Thank you for the script. I relatively new to scripting and used your script. Unfortunately, it only removes the watermark on the first page only and not the entire document. How can I remove the watermark in all of the pages.

You need to find out what their names are. All watermarks added by Acrobat will be called "Watermark".
