Convert PDF to JPEG with adding watermarm

Hello,
we are testing the aspos.pdf Suite. In an existing workflow we Need to convert a PDF-file to jpegs and adding to each converted jpeg a watermark.
Is this possible in one step at exporting to jpeg?
Or do I have to copy the original PDF file, add the watermark to the copied PDF and Export this PDF to jpeg?
Regards
Joerg

Thank you for contacting support.

Please note that Aspose.PDF API can be used to manipulate PDF documents but not the images. Therefore, you would need to add watermark to a page in PDF document and then convert resultant page to an image as per your requirements. Please visit below documentation articles for your kind reference.

We hope this will be helpful. Please feel free to contact us if you need any further assistance.
