Crimsonlogic - OCR Errors

To perform and use the OCR features in PDF Xchange,
a) First Need to convert the Images, doc, etc to PDF format right?
This is using the Took SDK, right?

i) In the mail below, as informed the Tool SDK is end of live, thus recommended to use CORE API with the long new license key.
Can you provide use the sample code to do this?? We need it in C++.
(there is no proper place in Tracker website or files to refer to understand how to use or get the commands)

ii) Am I correct that this conversion uses the printer driver “PDF XCHANGE printer 2012”
We have an issue where the conversion prints to the printer.
The default printer is not defined as “PDF XCHANGE printer 2012”, it is set as other physical printer.

Please advise is there any setting or codes that will not cause this to happen during conversion?

b) After the conversion to PDF, then we can use the OCR SDK to OCR the PDF file right?
Understand from the web, OCR SDK is found in the PRO SDK we bought.

i) Am I correct that we have to use the OLD LICENSE KEY for the OCR SDK?’
This is very confusing as please advise can only use one license key??

ii) There is an issue where the OCR cannot perform and always throws

iii) It cannot OCR for converted files of more than 17 pages
iv) It cannot OCR for converted files with comments

Please advise is there any setting or codes which can help resolve the OCR issues?
(Attached the testing docs and the converted copy for your testing)

Is there any easier way and one step to perform convert to PDF and then OCR together?

Hello crimsonlogic,

1) As for the sample on the Core API - please provide a short but detailed description of what needs to be done and we'll try to write you a sample.

2) If you are printing with PDF X-CHANGE printer 2012 then I don't see why do you need to go through the OCR process - the printer itself will already extract the text so you can select it and work with it (as I can see it in your files).

3) As a temporary fix-up you can OCR the document by parts (for example 15 pages at a time) and then merge them to one document.

4) The error code means OCR_ERR_INVALID_DICT_PATH meaning that you gave wrong path to the dictionary folder.

Also - please be aware a license for both PDF-Tools and the Core API SDK DO NOT entitle you to use the OCR SDK - the OCR SDK requires a license to either The PDF-XChange full PRO SDK or the PDF-XChange SDK.

PDF-Tools SDK and its successor the CORE API SDK have never included the OCR SDK.

If you do have a full PRO SDK license - please email as licensing issues cannot easily be answered here as serial keys should not be published in the open forums.
