Hello whoit, You'll only need to use the PDFXCoreAPI.x86.dll or the PDFXCoreAPI.x64.dll that will be downloaded with your Core API SDK copy. You can get it here: https://www.pdf-xchange.com/product/pdf-xchange-core-api-sdk/download HTH, Alex Perfect! One follow-up question: When I downloaded and in...

Hi - I've been informed that I need to use the CORE APIs to perform some of the PDF manipulation that I need done. I own PDF-XChange Pro SDK However, I cannot for the life of me figure out which dll/ocx to add to my VB project. Can you please explicitly tell me which components are required to use C...

So, to make sure I have this correctly: In the free viewer I can choose to keep the original content or convert to bitmap when using OCR, but in the SDK I can only convert to bitmap when using OCR? If this is the case, what are the plans to offer the 'keep original content' via SDK? This seems to be...

We're a developer (have been for many years).

I keep writing "ocx" but I'm referring to the OCR dll(s) and API.

What I'm saying is that in the Viewer I have two options,
but in the OCX I do not see the same two options - I can only get the original output as a bitmap plus a new ocr text layer.

How do I keep the original plus the ocr text layer like I can do in the viewer?

Success!

Changing the dll files worked - thanks!

I've noticed that within the free viewer (mentioned in my earlier posts) that when using OCR these two options are available: 1) Preserve Original Content & Add Text Layer 2) Convert Page Content to Image Only - Add text As A Layer When I use the OCX, there is a dpi option which clearly controls...

OK - thanks. I've passed the email on to our Tech.

I'll post back when we have word on success/failure.

Hi Stefan - Ok, I don't know what's going on here but I just tried OCRing the same files as before, at 300 dpi, at 600 DPI, and leaving the native layer alone. Didn't have any problems at all with any of the three tests. I'm on Windows 7 Pro 64bit Memory maxed out around 2.8gb when I used 600 dpi, s...

Hi Stefan -
Thanks for replying - we are using a licensed Pro version.

Order #: U6721399202

Do we need more than one license key within our code for handling OCR plus the other components?

Hi John -

Yes, I've actually tried that already and found the same results.
In fact, I first noticed it when testing using the Free viewer: v2.5 build313.1

I've found that if I try to OCR a large format file (E size, D size, etc) at 300 dpi, it fails. However, the same files is successful when the dpi is set to 200. Has anyone found a fix for this? Is there a minimum dpi setting that is accurate? In other words, after a certain DPI setting is there not...

Hi - I'm trying to create a user option whereby the OCR'ing of a incoming PDF can be skipped if the PDF does not contain any BITMAPs. In other words, and incoming PDF that is all text would be skipped. Is there a way, using any part of the Tracker library, to determine if the incoming PDF contains a...

We're testing the new OCR ocx and finding that only the first two pages of a document get saved, even though it appears to process all of them. In the free viewer, the output is always complete, just not via the ocx. I've attached a 3-page sample document that correctly OCRs in the free viewer (PDFX...

OK, I've found a generic file that causes the same memory errors - I have emailed it to support, referencing this post.

Thank You.

OK - I've done a bit more testing. First, I used PDF-XChange PRO 5 SDK\DSErrorLookup.exe and entered the error from my first post (-1039334424) and got back: Severity: Failure Facility: Frame buffer Description: Insufficient memory Then I re-ran "ocrtestapp.exe" and tried a file - it faile...

Unfortunately these documents are not my IP and I had to sign an NDA to get them from my client, so I cannot send them to you. Certainly there must be other ways to determine why the View OCR works but the dev dll does not? Maybe I can start by checking each dll's specs - size, date, version, etc.? ...

I'll give that a try and post back.

But in the meantime, how could that cause some documents to ocr and others to error?

EDIT: Nope-didn't solve the problem - behavior is the same - some files ocr fine, others do not.
All of them work in the Viewer....

I've installed and tested OCR using PDFX-Change Viewer v2.5 build 313.1 (Windows 7 64 bit OS) and for my 13 sample file the results have been excellent. However, when I use the Example VB6 code (PDF-XChange PRO 5 SDK\Examples\OcrSDKExamples\VB6 Example) most, but not all of the same files fail with ...
