Problem converting a PDF page with OCR, help please!

[CliveO]

Hi All,

I am new to this forum and I am hoping this might be an easy fix for the experts.
I have found a few posts that have assisted in using OCR feature of the API, but mothing to help with this problem.
I have also searched the FullDemo C# solution, but it doesn't seem to cover the OCR feature at all.
If you look at the image below, you can see the the code runs all the way to the 'AsyncDoAndWaitForFinish", but then an unhandled exception occurs.
Any help appreciated.

Regards,
Clive

Hello Clive,

Was the operation itself created successfully? Maybe you are passing the null pointer to the Async method?

Cheers,

Hi Alex,

It does look like the Op was successfully created.
Although I do see lots of exceptions thrown in the input class.
And also the Inst class is slightly different.
Another point of interest, my company also use the desktop PDF-XChange editor, and I can OCR documents successfully.

Clive
