Yes; just download the latest live DLL package from the downloads page:

https://www.pdf-xchange.com/product/downloads/sdk

The 64 bit DLL is now included in it.

Also, what is this PDF class:

using PDF = Aspose.Pdf.Kit;

Does this tie in with the (Tracker) developer's license for the driver API somehow?

You may wish to try setting the flags to 14 (binary: 1110) instead of 15. Bit 1 sets the watermark to be on the background of the page. In this case I think it should be visible there, but I'm not 100% certain.

Walter-Tracker Supp

I am assuming that you have correctly placed your license key and developer code in the source file, here: PDFPrinter = (PXCComLib.CPXCPrinter)prnFactory.get_Printer("", "Simple PDF-XChange", "<REG KEY>" "<DEV CODE>"// "<YOUR REG KEY>", "<YOUR D...

While Ivan is testing this, I would like to report that I have not been able to reproduce the report with the latest version of Kaspersky 2012 (most recent virus definitions), Avira, and MalwareBytes. This is most likely a false detection by your specific system, or you had something else already on...

This appears to be the result of heuristic, or other generic, detection, which tries to find and report potentially dangerous objects based on partial matches with true viruses: http://en.wikipedia.org/wiki/Antivirus_software#Heuristics This type of scanning is very prone to false detections, and I ...

I was wondering if we could expect this feature to be added to PDFXChange Viewer, so that one can execute this through command line: PDFXCview.exe ocr -in=sample.pdf -out=sampleOCRed.pdf I need it because I quite often have a batch of pdfs that need to be OCRed. Here PDFXCview doesn't even need to ...

There is an indirect method that would let you do this with our SDKs which sounds like what you are already doing. You could use the Simple Viewer DLL to render each PDF page to a Windows memory device context (DC), then enumerate the pixels in that DC and test them for colour. You can render to DCs...

No problem

Thanks. If we get the information over the weekend we will attempt to reproduce the issue on Monday.

Hi Jeff, I'm sure you understand that we don't specifically support Mac... however, we will do the best we can to sort out what the problem is. To do this, we really need to know specifically what emulator or virtual machine she is using. Without knowing this, there's just no way we can help. We nee...

I admire your enthusiasm for learning programming, but unfortunately this falls outside of the scope of our developer support. I would recommend a visual basic tutorial if you want to learn how to compile applications. If you get to the point where you would like support for our developer products, ...

If you have a scanner with document feeder, you can do this directly from File->NewDocument->From Scanner... If you only have a flatbed, you can scan multiple images into the dialog accessed from File->New Document->From Images. Just click the "import" button at the bottom of the page and ...

It looks like you have set the flags argument to "796" in the image watermark case, binary 1100011100... I'm not sure what the high bits are intended to do here but they will probably be ignored... however, since the second last bit is not set it will not be visible in the viewer. I just n...

Thank you; I will take a look and get back to you asap.

In addition to the solution John mentioned above, the PDF-XChange PRO SDK or PDF Tools SDK may also have what you are looking for; please review the features here and let us know if you have questions: https://www.pdf-xchange.com/product/pdf-tools-sdk https://www.pdf-xchange.com/product/pdf-xchange-...

You say she's running it in an emulator, not a virtual machine (e.g. parallels or VMware) or bootcamp, right? In that case I suppose there's something buggy in the way it handles windows system calls and it wouldn't really be anything we could do much about. What is the emulator? CrossOver? If it's ...

Walter-Tracker Supp

I fully understand your position on this. I think it is worth giving you some background into the OCR add-on. This is not a headline feature for us but is something we have been developing primarily for our next, upcoming major version. A couple of months ago we decided to include some of the initia...

The C++ header is included in the SDK:

C:\Program Files\Tracker Software\PDF-XChange PRO 4 SDK\Examples\Include

ocrtools.h
ocr_types.h
ocr_errors.h
OCRdefaults.h

I hope this is all that you will need. If not, let us know.

Sure, just use the simple viewer DLL. Load the PDF with the function: PXCV_ReadDocumentW() Print it with: PXCV_DrawPageToDC(), passing the flag pxvrm_Printing to the "RenderTarget" member of PXV_CommonRenderParameters. See the PDF-XChange Viewer Simple DLL documentation for more details. N...

Unfortunately we do not at the moment; the OCR SDK was added as a bonus a few months ago, but we have only provided a few examples, as the bulk of our development is focused on our upcoming new releases (including updated OCR components with more advanced functionality).

Please note that it is a limited, demo version that will only function on the first two pages of any input document. However, it provides a full demonstration of all functionality, subject to that limitation.

We have built the 64-bit version of the DLL and will include it in the main SDK installer in the near future. In the meantime I have sent you a copy directly via email (and can provide the same to other interested developers who may read this, if it has not yet made its way into the main installer)....

There are a couple of options for printing. You can print from the simple Viewer SDK by creating a printer device context (DC) with microsoft API calls and then rendering the page to that DC (there is a flag to specify that rendering is going to print). You can also print from the Active X Viewer DL...

Thanks for your fast reply that at least enabled me to apply a quick patch to the CAD program i'm working on (producing invalid pdf was a serious bug for our clients). The patch is simply to reset the dashoffset to 0 each time i call Graphics.DrawLine; the dashstyle is therefore not 'continuous' fr...

I'm glad you are getting good use out of the OCR feature! As for editing the results, at the moment it is not possible although this is a feature we anticipate adding during some point in product development. In fact we do have it slated as one of the features for the OCR plugin for the new viewer, ...

The problem here is that you are using PXCp _WriteDocumentW() to save the document where you should be using the equivalent PXC function, which is PXC _WriteDocumentW(). This is because you have been using PXC functions for creation of the document (PXC_Init(), PXC_AddImageW(), etc). The document ty...

I believe you will need to use PXC_GetPagesCount() to determine the number of pages. This function does not return a pointer to some internal page count, so you need to call it to refresh the page count as needed (e.g. after every new page is added). As for your error message (document not read), I ...

Hi, C# is not my area of expertise (I usually handle C++ related inquiries) but I will be looking into this for you as I am familiar with the usage of our products. The first thing I would recommend is making sure that you do not use the same watermark name for each watermark. This is set with the f...

What's the name or the ID of the new OCR Pages toolbar button. I wanted to disable this using the SDK but couldn't find the name of the button in the documentation. I believe it is OCRPages. You can find the names of all named commands in the FullDemo.exe demo application, under the "Commands&...

Jeff, I think there is some confusion with version numbers. Build 202 would refer to the PDF-X Viewer *end user* product (and I suppose Active-X). The OCR DLL included with the Tools SDK is at version 1.0.10. Have you tried the currently available DLL with your existing delphi wrapper? The only chan...

My apologies, I misread your original post - I guess you aren't interested in the SDKs.

Actually, the OCR library allows deskewing. There is a flag you can pass to the function OCR_MakeSearchable(). It can either use a page layout method (identifying text lines and then aligning them to horizontal), or an image-based deskewing using image projection histograms. You need not perform OCR...

Sorry, the use of the word "beta" is a mistake in the manual (which was written back when we only had an internal beta). This is not a beta release, this is a true release. However we do not support passworded documents at the moment. You will have to remove the password (e.g. with the oth...

Crop white space only crops completely empty space around the margins of the PDF page; it is not based on colour.

The data directory, input and output filenames are hard coded in the source code, so this is obviously a very barebones application. Please modify to suit your tastes.
