I correctly setup Forge Viewer for loading local PDFs, using integrated extension Autodesk.PDF.
Some PDF are visualized in mirrored view, unlike when opened in Acrobat Reader.
I do not make any call to rotate/resize PDF, so we think the problem is related to these PDF and how Autodesk.PDF render it.
I can share PDF if needed for testing
Using this approach, I was able to reproduce your issue with Viewer 7.37.
Let's use one of the pdfs provided as an example:
Here we have the pdf with Viewer 7.37:
And below, we have the one using Viewer 7.38:
This might occur on your end due to a caching problem.
Can you please ensure you have the latest version (7.38 as of March 2021). If the problem persists, please share the PDF.

When a PDF document is protected with a security policy from Adobe LiveCycle ES or Adobe AEM Forms, it can only be opened by Adobe Reader. Here's what it looks like when you try to open it in another PDF viewer.
Microsoft Edge:
Firefox (internally uses PDF.js):
But I have seen secured PDF documents that in other viewers show customised instructions to download and install Adobe Reader. Obviously there is a way to add unprotected content to protected PDF files, that other PDF viewers will display. How can I do it?
Here's an example of a PDF file I'm talking about.
When opened in Adobe Reader:
When opened in Firefox:
I also posted this question on Adobe forums, and someone replied with the correct answer there. AEM Forms has a feature that allows to add cover page to a policy-protected document: https://help.adobe.com/en_US/AEMForms/6.1/RMHelp/WS2d2a17056e219198-31ba356e14172797744-8000.html
I believe the only way to do what you are asking would be to supply the 'custom content' during initial authoring of the PDF with Adobe LiveCycle ES for instance.
(How this is accomplished may be similar to how it works for dynamic XFA content where the page contains some content that non-XFA compliant readers can fallback on to display instead of just erring out.)
But I think the only way to add such content to an existing PDF using non-Adobe software would involve violating the Rights Managment policy the author intended, which is not something you want to do.
In my iOS app, I would like to regenerate an existing pdf into another pdf after the users are done annotating on the existing pdf.
My regenerated pdf should be an exact replica of the existing pdf but should have embedded annotations and highlights etc which can be opened and viewed on desktops as well.
I have done some research on this including the solutions proposed on other SO posts. I have tried libharu etc.
But somehow I am not able to convert an existing pdf into a replica pdf. I am able to add annotations to a new pdf I create using libharu.
Now my problem is to copy the existing pdf as is to my regenerated pdf. Any pointers will be much helpful.
My understanding is that a library that can save back out a PDF with "true" annotations (those that can be hidden in Acrobat, for example) is not something that exists in a FOSS solution.
LibHaru, for example, only supports creating new PDFs, not editing or appending existing PDFs. From their homepage:
At this moment libHaru does not support reading and editing existing
PDF files and it's unlikely this support will ever appear.
You can render the PDF on a page by page basis, and then re-save it with some additional information. This S.O question has a reasonable looking piece of code. That will save any "annotations" more as an image in the PDF itself, though.
You might try a paid library like PDFNet.
I am looking for a lightweight pdf viewer ( commercial / free) for my windows application.
I presently display the pdf documents on a webbrowser with Adobe Reader Plug-ins.
Background :
The problem i am having with Adobe Reader is the Loading time. To display a pdf document for the very first time, Adobe Reader nearly takes 15 seconds !! .The application when deployed on customer locations (usually run on Windows Embedded OS) the pdf viewing time is still worse, sometimes takes more than a minute.
Hence i need to find an alternative for Adobe Reader.
My simple requirements are :
Lightweight - viewer should initialise itself and load the pdf as
fast as possible.
SVG support.
If anyone has any idea regarding such a tool. Kindly let me know
Regards

Try : Foxit PDF SDK
Try SumatraPDF (Download full kit for MOZ plugin npPDFViewer.dll sorry there is NO IE.OCX)
For a minimal install use with the portable executable in same directory and you can call via DDE or command line
I think best light weight option for Windows is MuPDF for those who would rather not use any plugin in the Chrome.

We are using Blackberries to display PDF reports. Here are background details on the problem:
The PDF reports are created using JasperReports.
Report format can be changed.
Different report formats are available (as per the feature set of JasperReports).
The PDF reports are on a website, too, so retaining a single source is ideal.
The page setup is in Landscape.
Here are the issues we have encountered:
Users cannot see a full line of text on the Blackberry.
The size of the PDF and UI makes reading difficult, at best.
The menu option to convert the PDF to text loses too much formatting to be useful.
The text is blurry (and too small).
Here are solutions we have thought about:
Create a second report (not ideal) in text or HTML format.
Simplify the original report format (not really an option, given the amount of data).
What other options are there for making a report available on the Blackberry, given the constraints of JaserReports, such that the report:
Is legible?
Is formatted for readability?
Displays quickly?
Essentially, we'd like to make sure there are no simple solutions we have overlooked for displaying legible PDFs on Blackberries.
We convert TIFFs to PDF for one of our applications, and have had mixed results with BlackBerry PDF viewers. These were our results.
Working
The following PDF readers worked for our purposes:
RepliGo Reader v1.1.1.1 - $19.95
Works fine.
DataViz Documents To Go Premium Edition v1.003.001 - $49.99
Works and includes a word wrap option to get the current zoom level to fit the available screen width, by moving text onto subsequent lines. Might fit your needs.
Non-Working
The following PDF readers did not work for our purposes:
BeamReader v1.0.8 - $17.99
BeamSuite v3.0.2 - $49.99
These couldn't open our PDF files ("Unsupported document format"). In addition they did not register as a PDF content handler, required for our application.
MasterDoc - $19.95
eOffice - $29.95
These also did not register as a PDF content handler. We had a range of problems with these, including installation issues, and not being able to open any PDFs at all.

I hear it's the best at reading PDFs for BlackBerry
How about outputting the file to an RTF or an image file (JPG/GIF), and then viewing them in your web browser?
If that doesn't work well on the native browser, I would focus on viewing the file via some other web browser - for example, Opera Mini. I know for images it's easier to navigate "big" images in Opera Mini than the native browser.
If your blackberries are on a BES server, couldn't you display the reports as HTML on your corporate intranet? - Then you could email a link to the blackberry and simply browse the report.
You can convert pdf to image via xpdf and than show image. xpdf is a BEST renderer of pdf.
I've already referred to this SO post. I've been embedding images using an AlternateView for PNG files. Now I'm wondering how to do it with PDFs.
Should it work, for the LinkedResource, to just say:
Dim document As New LinkedResource(pdfFilePath, "image/pdf")
I'm just trying to figure out how to get the PDF to be embedded like I could with an image, or is that not possible and I'll have to do it as an attachment?
You can embed images since they can be rendered in place by an email client. PDFs cannot do that, so I'd recommend either having a thumbnail of the PDF that links to your web site with the actual PDF. Or just attach the PDF to the email message.
There are a few options that I know of.
1) Is the simplest way okay? The easiest by far would be to attach the PDF as a normal attachment. Then render the first page of the pdf as an image, embed it in the email and link it to open the PDF if you can. Entourage kind of does this on the Mac.
Alternatively, what I found was the following:
2) FLASHPAPER embedded in HTML displaying a PDF. Adobe has a technology called Flashpaper. It is a flash based file viewer. You can use flashpaper format documents that go into it, or PDFs as the source.
Check out some examples. That's really flash. http://www.adobe.com/products/flashpaper/examples/
Assuming you send an HTML email that will get through (images aren't turned off, etc), you can can embed the Flashpaper viewer right in your HTML code as a normal Flash object.
Most HTML email clients use Internet Explorer Bits, Webkit bits, or Gecko bits to render the html. Flash player is pretty well installed on everything, so it works well. A good example of this is when we open an email and it has video playing in it. It's almost always Flash.
I have had luck doing it this way -- the only thing you'd have to decide is if most of your clients can see this and how much (if any) today's software might block it.
What I ended up doing was a hybrid. 1) Attach it to the email, 2) Embed the Flashpaper viewer. They get it either way.
Flashpaper is available seperately for $75. It has come in handy where the client was not able to install adobe acrobat on each computer and it had to be 100% web based.
I would imagine you should be able to do the same using any language with a little more effort and using something like Flashpaper.
Hope that helps
This is not possible--at least not in a way that will work with many clients. You'll need to just attach the file.
If you have only one client to worry about, it might be possible--but not likely without manually changing settings on each client.
The MIME type of a PDF is "application/pdf" not "image/pdf"
