We have been receiving complaints on how bad the PDF looks in Adobe Acrobat Reader DC but looks fine in Chrome PDF Viewer.

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?

Hi Fletcher,

the functions...
SetOpenActionDestination,
SetOpenActionDestinationFull and
SetViewerPreferences you'll know already?
Perhaps with these functions you can have some influences on how to show the pdf after open?

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

If not, it will be better to have some mal displayed sample pdfs to test ourselves...
Cheers,
Ingo

It is a bit different.  The thing is the PDF have done it's job, so the only thing is it rendered differently, when viewing in both Chrome & Adobe Reader.  Here attached are the 4 files below.

How do you attach the files to this forum post?

You can upload them anywhere on a free file hoster or - if available - on own webspace.

Chrome uses PDFium as renderer.
Acrobat has its own render functionality.
QuickPDF offers functionality to select a special renderer.

Here's a how to regarding rendering:
https://www.debenu.com/kb/use-rendering-printing-add-debenu-quick-pdf-library/

With SelectRenderer you can make some tries with different renderer engines like GDI+, Cairo, DPLR (AGG) or PDFium:

Well that's suck!  Here you go!  You'll need to download the file when you get to that website url.  There are 2 testcases, 1) Buyer Guide & 2) Whatever.   The JPEG image show the difference between Chrome & Adobe Acrobat Reader DC.  The PDF is the testcase file that got viewed in Chrome & Adobe Acrobat Reader DC.

Well, you asked me to use Free Hosting for the files & we don't know which one to use?

We need a solution to the Quick PDF because customers been calling!

Dropbox you can use without sending an email address for download.
But i think THIS is the wrong place here for you.
This here is a small community with and for developers.
If there's some time we can support a little bit with an idea or a few lines of code. Sometimes we can post samples for special usage.
If you can explain your problem in a detailed way and if you think that's a library error then you should post it on the official support page from Foxit/Debenu.
BTW: I've inserted my email adress and the form tells me:
"Please provide a valid email address." ;-)
A second address works... But the promised link doesn't arrive :(
I've tried some of my pdf-files with Chrome, Sumatra, Foxit and Acro... If there are any differences i don't see them.
Did you try different renderers?
You didn't post any code so that's all i can tell.
Sorry.
Cheers,
Ingo

This is not related to QuickPDF rather to AcrobatReader - install different AcrobatReader version and it will be fine.
We have the same problem with PDF Invoces generated from some ERP program (not related to QuickPDF).

Did you try to use NormalizePage() ?

; get number of Page
Local $iTotalPages = $oQP.PageCount

; normalize all page
For $iCurrentPage = 1 To $iTotalPages
$oQP.SelectPage($iCurrentPage)
$oQP.NormalizePage($iNormalizeOptions)
Next

Do you attach fonts with your PDF ?

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

>> Dropbox you can use without sending an email address for download.

Here's the DropBox url.  https://www.dropbox.com/sh/8a35afhdkax2agp/AADwJ8SOtLaeuWZlicLVZ6Waa?dl=0

>> But i think THIS is the wrong place here for you.  This here is a small community with and for developers.

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.

>> If you can explain your problem in a detailed way and if you think that's a library error then you should post it on the official support page from Foxit/Debenu.

We did that for few different issues & still haven't heard back for a few months now.  That does suck for us here unfortunately.  One of us called the employer's employee there in another country & talked a little but that employee was so swapped with other stuff.  So, we're kinda stuck here with not much help.  Oh well

>> This is not related to QuickPDF rather to AcrobatReader - install different AcrobatReader version and it will be fine.

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.

Will take a look at your other link.

Any other solutions you have on solving the Chrome PDF & Adobe PDF difference will be great!

Our script is below.  I had to copy & paste them from several files into 1 short version script.

--snip--

    public class FormPDFService : IFormPDFService

            _amazonManagerService = amazonManagerService;
            _formService = formService;
        }

        public byte[] GetMappedFormToPrint(FormWriter formWriter, bool isDocuSign)
        {
            var pdfBytes = new byte[] { };
            var pdfApp = _pdfEditorService.PdfInitialize();
            var pdfFilename = formDescription.ToLower().EndsWith(".pdf") ? $"{formDescription}" : $"{formDescription}.pdf";
            var azureKeyName = $"{formWriter.Company.DealPackAcctNo}/Foo PDF/{pdfFilename}";

            formWriter.PdfTemplateLocation = pdfFilename;

            using (var pdfFileStream = _amazonManagerService.GetPdfTemplate(azureKeyName))
            using (var ms = new MemoryStream())
            {
                pdfFileStream.CopyTo(ms);
                pdfBytes = ms.ToArray();

                }

                    }
                    else if (string.IsNullOrEmpty(fieldValue))  
                    {
                        // Notice: We can't assign any blank value here, or it will wipe out the PDF's default value that our employer's Support staff programmed it with in Adobe Professional.
                        continue;
                    }

                    if (pdfApp.SetFormFieldValueByTitle(fieldName, fieldValue) == 0)
                    {
                        var error1 = pdfApp.LastRenderError();  // https://www.debenu.com/docs/pdf_library_reference/LastErrorCode.php

I've tried to open the pdf-forms with these browsers:
Microsoft Edge, Cliqz, Google Chrome and Firefox Quantum.
I've tried to open the pdf-forms with Sumatra and Foxit.
I've always the same issues that you've already described.

Then i've used Adobe Reader DC... and it works fine.
It works fine with a pdf made by Adobe... THIS smells a bit strange :(
It seems to me that Adobe wants its investments secured :(

Otherwise, i agree with mLipok's opinion.
For me it's not a problem of QuickPDF.
The best address for your issue is the adobe-support.
Cheers,
Ingo

@Ingo did you just say that you have oposite issue... 

I mean:

Your case is:
Works well only in AdobeReader

fletchsod case is:
Do not work well only in AdobeReader 

?

I came to the same conclusion as Ingo. The files looked better in Adobe, as one often finds. though perhaps not perfect (the OP does not list precisely what is incorrect).  Some other rendering also inserted > between the words, instead of spaces, but who knows if perhaps they were part of the design. I could reproduce this.

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.

As I understand the problem is only on customers machine not on yours.
I do not that you should change yours system.
Try to check if customer after using older Acrobat Reader version will have the same issue.


"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."

Both samples work well with Acrobat Reader DC... ONLY with Acrobat Reader DC.
All other apps have the issues described by Fletch already.
Due to this behavior i would ask Adobe first!

This i've found in the pdf-content:
"...
<</Type/CMap/CMapName/Adobe-Identity-UCS/CIDSystemInfo<</Registry(Adobe)/Ordering(Identity)/Supplement 0>>
..."
"Adobe-Identity-UCS" is the key i think that it only works with another Adobe-product in a proper way?

You're telling that the template is made by Adobe Acrobat.
When i look into the resulting pdf i see that it's generated with "PDF Clown".
An open source library for Java/.NET with no further developement for more than three years now.
I've read from users, telling that the library isn't ready yet.

In this pdf-samples are at least two construction sites and should be examined by the human creators step by step.
I would like to help but here i'm out now.
Cheers,
Ingo

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.
