Hell Support,
I am working with the team for our Aspose use cases on document related requirements. We ran into an issue while trying to import the appose-pdf library and were hoping you could assist us with this.
The intent right now is to be able to perform some modifications on PDF documents [ covert to docx format or add or remove watermarks]

To modify PDF documents using Aspose.PDF, you can perform tasks such as converting to DOCX format or adding/removing watermarks. Here are some examples to help you get started:

  1. Convert PDF to DOCX:

    using Aspose.Pdf;

// Load the PDF document
Document pdfDocument = new Document("input.pdf");

// Save as DOCX
pdfDocument.Save("output.docx");

  2. Add a Watermark:

    using Aspose.Pdf;
using Aspose.Pdf.Text;

// Load the PDF document
Document pdfDocument = new Document("input.pdf");

// Create a TextStamp for the watermark
TextStamp textStamp = new TextStamp("Watermark Text")
{
    Background = true,
    Opacity = 0.5,
    HorizontalAlignment = HorizontalAlignment.Center,
    VerticalAlignment = VerticalAlignment.Center
};

// Add the watermark to each page
foreach (Page page in pdfDocument.Pages)
{
    page.AddStamp(textStamp);
}

// Save the modified document
pdfDocument.Save("output_with_watermark.pdf");

  3. Remove a Watermark:
    To remove a watermark, you need to identify the stamp that was added. This typically involves iterating through the stamps on each page and removing the specific one you want to delete.

If you encounter issues importing the Aspose.PDF library, ensure that you have the correct version installed and referenced in your project. For more detailed guidance, please consult the official documentation.
