Add Text Watermark ​

To add a text watermark, follow these steps:

  1. Use CPDFReaderWidget to display the PDF document.
  2. Set the required properties for the text watermark using CPDFReaderWidgetController, including content, font, color, and size.
  3. Configure general watermark properties.

Here’s an example of how to create a text watermark:

dart
late CPDFReaderWidgetController _controller;

@override
Widget build(BuildContext context) {
  return Scaffold(
    resizeToAvoidBottomInset: false,
    appBar: AppBar(),
    body: Column(children: [
      TextButton(onPressed: () async{
        await _controller.document.createWatermark(CPDFWatermark.text(
          textContent: 'ComPDFKit',
          scale: 1.0,
          fontSize: 60,
          rotation: 0,
          horizontalAlignment: CPDFWatermarkHorizontalAlignment.center,
          verticalAlignment: CPDFWatermarkVerticalAlignment.center,
          textColor: Colors.red,
          pages: [0, 1, 2, 3]));
      }, child: const Text('Add Text Watermark')),
      Expanded(child: CPDFReaderWidget(
        document: widget.documentPath,
        configuration: CPDFConfiguration(),
        onCreated: (controller) {
          setState(() {
            _controller = controller;
          });
        },
      ))
    ],));
}
