Tesseract User Licence

[Buehli]

I would like to use Tesseract as a part of a commercial application.
Is there any licence for that - or is it free ? What rules do I have
to follow ? Thanks, Buehli

Hi Buehli,

I think that it is possible to use tesseract as part of a commercial
application (for free) because tesseract is licendsed under licensed
under Apache2.0.
But you should read the rules and details in then License
Documentation.

1. Have a look at the the file "COPYING" in the tesseract package

2. Have a look at http://www.apache.org/licenses/LICENSE-2.0

Lothar,

Thank you for your reply.

I read the Apache License. However, this license is aimed at developers and not so much for users and commercial redistributors.
The COPYING file says: "If you want to use it for commercial gain you must contact the MITRE corporation."

 

So, maybe it's not free ...

 

Regards,

Buehli

Hi Buehli,

you should have a look in the COPYING of current (!!!) version of
tesseract (2.03).

The MITRE corporation was for the Aspirin/MIGRAINES system.

The current COPYING says: "The Aspirin/MIGRAINES system is no longer
used."



Regards,

Lothar

You are right !

Thank you.

Hi Simon,

Tesseract used to use a module from the Mitre Corporation, but this has been removed. It is now completely licensed under the Apache 2 licence, which basically gives anyone the ability to use it for any purpose without royalty encumbrances. In using it in a commercial product, about the only thing you have to do is provide a copy of the Apache 2 license along with the end product. You also have to retain the copyright notices on your own copy of the source code, but you don't have to redistribute it.

Glad to see another use of Tesseract!
Ray.

Ray,

Thank you very much for your details.

That helps us a lot. If we start using Tesseract, I'm sure we will be able to contribute to your project via optimizations as well.

 

But before using, we have to implement it. And that's where I am not sure:

Our software is programmed in Visual Basic 2005 using Microsoft Visual Studio. 

Is there any possibility to implement Tesseract to our project ?

 

Thanks !

Simon

Hi Simon,

have a look on the thread here in this forum with the Subject
"Tessnet2 a .NET assembly using Tesseract engine". Remi has built
a .NET Wrapper for tesseract.
Here the URL for this project: http://www.pixel-technology.com/freeware/tessnet2

I have converted his C# sample application to VB.NET 2008 some days
ago. You will find it at http://www.dornieden.org/tessnet2/Tessnet2VB2008.zip

Lothar
