We are preparing a code example for this requirement under the task ID PDFNET-52301. As soon as the task is completed, we will share information with you.
Please accept our humble apology if any of our responses felt unpleasant. We only ask for sample files (e.g. source and expected output) when some requirements need to be investigated whether they can be achieved or not. We could try to create an expected output PDF based on our assumption but keeping PDF format in view, we could not really say that two apparently identical PDF files are the same. They could differ in many ways in their structures and element sequences.
Above are some main factors and reasons why we mostly request to share a sample document or expected output or anything else related to a code snippet and environment details. Nevertheless, we will soon get back to you as soon as the code sample is ready.
