Add Watermark To Pdf In Preview For Mac



This article is for developers seeking help on how to add a watermark programmatically within a PDF. A watermark is a recognizable image or pattern, a common way to identify work and discourage its unauthorized use. A visible watermark can’t prevent unauthorized use. But it makes it more difficult for people who want to claim someone else’s photo or artwork as their own.

In PDF, a watermark is text or an image that appears either in front of or behind existing document content, like a stamp. For example, you could apply a “Confidential” watermark to pages with sensitive information. You can add multiple watermarks to one or more PDFs, but it's necessary to add each watermark separately. You can specify the page or range of pages on which each watermark appears.

You can add watermark to a PDF through the user interface, or by using C++ code or JavaScript APIs.

Let’s look at how easy is to use watermarks and backgrounds with Foxit PhantomPDF Mac. Add a watermark. To add a watermark to your PDF, go to the “Edit” tab. Next, select “Watermark” and choose “Add”. Then, ensure that the text option is checked and insert the text you want to use as the watermark in the blank box.

    • To use an image as a watermark, select File. Then click Browse and select the image file. If the file has multiple pages with images, specify the Page Number you want.

There are two APIs that the Acrobat SDK offers for adding a watermark using C++

  1. void PDDocAddWatermarkFromText (). This API adds a text-based watermark to a page range in the given document. The syntax of this API is as below:

    void PDDocAddWatermarkFromText (

    PDDoc pdDoc,
    PDDocWatermarkTextParamsRec* pTextParams,
    PDDocAddWatermarkParamsRec* pParams
    );

    The details of parameter are below:

    • PdDoc is the document onto which watermark will be added.
    • TextParams is the structure describing the text-based watermark to be added.
    • pParams is the structure specifying how the watermark should be added to the document.
  2. void PDDocAddWatermarkFromPDPage (). This API adds a PDPage as a watermark to a page range in the given document. The syntax of this API is as below:

    void PDDocAddWatermarkFromPDPage (
    PDDoc pdDoc,
    PDPage pdPage,
    PDDocAddWatermarkParamsRec* pParams
    );

    The detail of parameters is as below:

    • pdDoc is the document onto which watermark will be added.

  1. addWatermarkFromText(). This API adds the given text as a watermark to the specified pages in the document. For example, code below adds “Confidential” as a watermark to the center of all pages of the current document: this.addWatermarkFromText(“Confidential”, 0, font.Helv, 24, color.red);
  2. addWatermarkFromFile(): This API adds a page as a watermark to the specified pages in the document. For example, code below adds first page of watermark.pdf as a watermark to the center of all pages of the current document: this.addWatermarkFromFile(“/C/temp/watermark.pdf”);
