Flatten entire PDF?

[rosanelli]

Is it possible to flatten an entire PDF or do I need to go through each annotatin/field?

You can iterate through the pages and call page.flatten_annotations, like I do in the hexapdf modify CLI command (see https://github.com/gettalong/hexapdf/blob/master/lib/hexapdf/cli/modify.rb#L122-L128).

If I'm not mistaken, there's a pdf.acro_form.flatten method to flatten entire document at once

[gettalong]

@ekzobrain Yes, this method exists but only flattens widget annotations of an AcroForm, not all annotations.
