…ed PDF's. PDF viewing software such as preview and acrobat reader auto positions the unflattened form fields when the user views the PDF file in it. But the `pdftk` library doesn't auto position fields before flattening. The `pdftk` does support the ability to create better-positioned fields without flattening using its `need_appearances` option. ref. https://www.pdflabs.com/docs/pdftk-man-page/#dest-output-need-appearances So, we are using a multi-step approach to get the same quality from the `pdftk`, which does the following: 1. fill-up the form with the `need_appearances` flag and without the `flatten` flag 2. regenerating the flattened file out of the non-flattened PDF file, which has better positioning. Empirical results have shown massive improvements in the quality of the generated PDF's: https://ibb.co/KLqtYJC
