Hello,
I received the trial license key for the ocr, but it doesn't work, it keeps saying that it is unregistered, and I can't test it by returning the ocr as string.
Thanks.
Marcio.

Hi Marco,

Maybe you are not unlocking all features. You have to call both SetLicenseNumber() & SetLicenseNumberOCRTesseract() functions.

If you need more assistance, report code you are using to unlock the toolkit.

Kind regards,

Loïc

Hello Loic,
I tested it and bought OCR License Key.
During my development it works fine under Win XP, but when running in a dedicated machine Win 2003 Server, it says that the license key is invalid.

Does OCR feature run on Win 2003 Server?

Thanks,
Marcio.

Hi Marcio,

Yes it should work on any Windows operating system. I suggest you to download the latest version of your toolkit available on gdpicture.com
In old release we got limitation for server, this limitation have been removed on latest edition.

With best regards,

I'm using GdPicture Pro 5, where can I download TesseractDictionnary ?

(not found in the FAQ)

[Loïc]

Hi,

The Dictionary files are included in GdPicture packages.

After installation you can find they into [INSTALLATION DIRECTORY]\Redist\OCR

With best regards,

Loïc

[AmoK]

Thank you for your reply !
I found files in this repertory [INSTALLATION DIRECTORY]\redist\optional\ocrdata

OCRTesseractDoOCR works fine

[Loïc]

Yes you are right !

[INSTALLATION DIRECTORY]\redist\optional\ocrdata for ActiveX editions

and

[INSTALLATION DIRECTORY]\redist\OCR for .NET

Kind regards,

Hello,

I was wondering is there going to be an implementation of Tesseract v3.0 in your OCR engine?
As I understood in Tesseract v3.0 there is a support for serbian language which would be tremendously useful for our applications!!
We would be ready to pay an extra fee for that specific version of Tesseract OCR engine.

Kind regards,
Blagoye

Hi,

Tesseract 3 is not yet releases. It is currently in beta stage. We will probably create another plugin for the new engine if it is still released under the Apache license.

Kind regards,

Now that Google has released v3.0, do you have any updates on time?

[Loïc]

Hi,

The next plugin V3 should be available within 2 months.

Good day,

Just checking the status of GDPicture with the new version of the Tesseract Engine? In addition to thread safe OCR, is performance looking considerably better in the new version of Tesseract?

Thank you for your time

[Loïc]

Hi,

We do not yet implemented this feature.
I am not sure that Tessract V3 is fully operational for multi-threading purpose. Also, we are still thinking about how to wrap the new engine.
We will probably release an open-source gateway between GdPicture & Tesseract V3 under Apache license. Currently investigations are in "on hold" step.
We will go back to this feature next year. We concentrate our efforts on GdPicture.NET 7.3 which will be released very soon.

Kind regards,

Loïc
