Add text watermarks Leave feedback

One of the main features of the GroupDocs.Watermark library is adding text watermarks to documents. You may add watermarks to documents or images from local disks, as well as from streams. For a full list of supported document formats, check Supported formats.

To add a text watermark perform follow next code sample:

const groupdocs.watermark = require('@groupdocs/groupdocs.watermark')

function addATextWatermark() {
  const watermarker = new groupdocs.watermark.Watermarker("sample.docx");

  const watermark = new groupdocs.watermark.TextWatermark('top secret', new groupdocs.watermark.Font('Arial', 36));
  watermark.setForegroundColor(groupdocs.watermark.Color.getRed());
  watermark.setHorizontalAlignment(groupdocs.watermark.HorizontalAlignment.Center);
  watermark.setVerticalAlignment(groupdocs.watermark.VerticalAlignment.Center);

  watermarker.add(watermark);
  watermarker.save("sample.docx");
  watermarker.close();
}

Run the program. A new watermarked document will appear in the specified path.

GroupDocs.Watermark offers many more capabilities for adding text watermarks. For example, it allows specifying background and foreground colors, formatting, text opacity, use of absolute or relative positioning, and so on.
