Add watermarks to PDF in Android

The WatermarkDialog allows you to stamp a PDF document with text that overlays each page of the document.

Show the watermark editor

The watermark editor can be shown from an activity by calling the following method:

Java

public void showWatermarkDialog(PDFViewCtrl pdfViewCtrl, FragmentManager fragmentManager) {
    WatermarkDialog fragment = WatermarkDialog.newInstance(pdfViewCtrl);
    fragment.show(fragmentManager);
}

Kotlin

fun showWatermarkDialog(pdfViewCtrl: PDFViewCtrl, fragmentManager: FragmentManager) {
    val fragment = WatermarkDialog.newInstance(pdfViewCtrl)
    fragment.show(fragmentManager)
}
