Aaron Eischeid commented on PDFBOX-2970:
----------------------------------------

I needed the flatten method recently as pdf.js in Firefox was not rendering content of a pdf with fields filled in.

The documented method didn't work for me the form is gone so it stops complaining, but the content I want to be present is missing. However, I found the undocumented one that flatten() calls is perfect for me. refreshAppearences seems to be a bit odd in that fonts get a little cut off or moved slightly, also empty fields which I used as placholders for placing images get a couple odd glyphs inserted, but overall pretty close.

also I already had the fields so makes sense to pass them in rather than have flatten look them up again for me. 

in short I think this method should be documented in the public docs.

public void flatten(List<PDField> fields, boolean refreshAppearances)
