[Bug]: flatten form field with text inside. Text is lost. #2006

The Problem

When I flatten a pdf with lots of form fields. I expect the text inside the forms to be saved and only form field removed.

Stirling remove all. No text visible after.

Is this a bug or design and how can I save the text inside the form field?

Seems like a bug could you provide an example pdf for testing?

Will work on this. Waiting for pdf

I've just run it again and I ticked the box "flatten form fields only" this time it worked it preserved the form but there's a partial corruption of the file meaning when I open the pdf in my pdf editor (pdf xchange) it reports red flag warning "ERRORS DETECTED IN THE XREF TABLE"

is this something expected or simple? i know it's not a big deal and could be ignored but i wish to find a way to clear this.

i will provide a sample pdf asap for you to test with yourself.

sample file. so if you tick "flatten form fields only" it works & preserves the text. but need to resolve the errors XREF after flattening.

@Frooodle can you assign me?

samsong commented 1 hour ago

Separate question. I want to use this as a web api but I cannot load the api documentation on swagger it is stuck on loading page.

Can you tell me what is the web api command to do flatten + form fields only?

@Frooodle this works https://stackoverflow.com/a/71159599.

editing pdfDocToWebResponse

        document.save(baos, CompressParameters.NO_COMPRESSION);

Is it worth it?
