Hello Forum and Tracker Support Team,
It is excellent that the OCR feature of PDF-XChange Editor can handle multiple languages simultaneously.
However, I noticed that OCR sometimes takes a long time to recognize text.
When multiple languages are selected such as shown below, for example with the attached document, PDF-XChange Editor takes about 1 minute per page on a fairly powerful PC. Admittedly, the quality of the document is poor, so trying to recognize multiple languages is probably particularly challenging.
So is this relatively low OCR speed expected behavior, or is there possible room for improvement?
Thank you
David

Hello David,
Thank you for your report.
There is an improvement coming up for the OCR tool that will affect its performance.
Currently, the OCR tool is not using the system resources in full, so probably this is the reason for the issue you are facing.
Regards.

Re: Multi-language OCR can take a long time
I'm blown away by the performance of the revamped OCR feature!
I just did a OCR test with 27 pages ("Searchable Image", English, accurracy "Automatic"), and got the following results:

Re: Multi-language OCR can take a long time
Thanks for posting this David,
I am really pleased to see this translate into real world result. It is one thing to perform well in tests in a controlled environment but the real proof of the pudding is you.
I am impressed with the work they did also, and would offer a big pat on the back to the team for pulling this off!
