We use Quick PDF to create new PDF but we don't know exactly what to look for, to tweak Quick PDF with to make it look better in Adobe Acrobat Reader DC.

So does anyone know how to adjust the Quick PDF (or perhap Adobe Acrobat Reader DC) to look like Chrome?    

Did you try to use NormalizePage() ?

Do you attach fonts with your PDF ?

Try also:
"Option 10 to ReplaceFonts removes embedded fonts if it matches the 14 standard fonts"

Well, we paid for Quick PDF through https://www.debenu.com/products/development/debenu-pdf-library/ & http://www.quickpdf.org/ .   They then pointed us to this forum.  Not your fault.  We haven't found any other forums for QUICK PDF by the way.

The customer is using the latest version of Adobe Acrobat Reader DC.   Our staff use Adobe Professional to create a PDF template.   I don't see how does changing the product help us, we can't simply change it cuz of 20+ years in using Adobe Professional to make those PDF templates & it is too much work to start over from scratch with different products.

I will take a look at NormalizePage().  We only use the Helvetica, Courier New font that is available as TTF on the server's local disk where Amazon software reside on.

Your case is:
Works well only in AdobeReader

It's not my programming language, so I am not going to comment on the code, but it looks to me as if the solution will require careful, controlled debugging, bug by bug, both of the original PDF and the added fields. Too many variables to devise a solution in the forum.

Font name: ??????


Are you using Arial + Hevletica + "ZapfDingbats" font ?

What this is "ZapfDingbats" font ?

We tried all of those suggestions being provided in this post.

1) 

   https://www.debenu.com/docs/pdf_library_reference/SetOpenActionDestination.php

   https://www.debenu.com/docs/pdf_library_reference/SetOpenActionDestinationFull.php

   https://www.debenu.com/docs/pdf_library_reference/SetViewerPreferences.php

2) Rendering engine

   https://www.debenu.com/kb/use-rendering-printing-add-debenu-quick-pdf-library/

   https://www.debenu.com/docs/pdf_library_reference/SelectRenderer.php

3) NormalizePage() & "Option 10 to ReplaceFonts removes embedded fonts if it matches the 14 standard fonts"

4) Whatever else here, etc.

They all still didn't fix our issues.  

Then we finally found the problem ourselves.  Phew.   It is a bug in Quick PDF after all.  From several posts & Google research, it showed this bug exists for 10+ years.  Further researches showed it is due to Quick PDF design limitations as it doesn't know what to do with field name duplications, so as a consequences those remaining fields got left blank.   

That would explain why confusing results & confusing feedbacks.  The reason it works in Chrome & not in Adobe Acrobat Reader DC is because Chrome broke apart the generated Quick PDF & made a new Chrome PDF, followed by plucking off some of the Quick PDF fragmentations & imported them into Chrome PDF which is why it works in Chrome.    As for Adobe Acrobat Reader DC, it just show as it is from what got generated by Quick PDF.

Since we can't rename the fields on 500+ PDF files.  So, we're gonna use Quick PDF API to rename the fields ourselves & that will take care of our issues.   Adobe support is not reliable as evidently shown in Adobe Flash, Adobe Director, Adobe Acrobat Reader, etc.  Also, we asked Adobe about it's new could product & learned it cost $5,000 to $80,000 based on how the product is being used.  So forget it, we'll be sticking with Quick PDF which cost $500 & we'll just do the field renaming ourselves.

Thanks.
