DTWAIN Licensing Information
A single Developer License is automatically granted to you once you purchase a single copy of the DynaRithmic TWAIN Library for $79 (non-PDF enabled) and $129 (for PDF-enabled version).
In addition, a Developer license must be purchased for each developer who works on a product or project using DTWAIN. No matter what type of applications are being developed, a separate DTWAIN Developer License must be purchased for each developer working with DTWAIN.
Distributing your DTWAIN applications
In addition to the Developer License described above, If you plan on distributing your DTWAIN applications under one or more of the following scenarios:
Public distribution of your application (commercial, freeware, shareware, etc.),
Use the DTWAIN applications in a company by more than one person
Distribute the application to other company sites
Use DTWAIN in a web-based application (Internet or Intranet)
then you must purchase at least one of the various Distribution Licenses described below, in addition to at least one Developer license. Otherwise, if you are using DTWAIN to create applications that you will personally use and/or will not distribute your programs to other companies for others to use, and you do not distribute the DTWAIN DLL and related files, you do not need a Distribution License. In other words, "personal use" applications do not need any additional Distribution Licenses.
For example, if you create an application that you personally use to scan images, and then on site at another company you use the same program but do not give ownership of the program to the company and the DTWAIN DLL's and other related components are not available to the company when your program is not in use, then you do not need any additional licenses. This still counts as "personal use" of DTWAIN.
Distribution License
A Distribution License grants you the rights to distribute your application to any number of individuals, and with exception of the Toolkit License, royalty-free, for an unlimited number of applications.
Distribution Licenses come in the following categories:
Company Distribution License
General Distribution License
Toolkit Distribution License
The Company Distribution license allows you to create an unlimited number of royalty-free applications that use DTWAIN, and distribute these programs within the same company at a single company site to any number of individuals. If the program will be used on a network, then a Company Distribution license is required. If the application will be used within an Intranet environment, a Company Distribution license must be purchased.
The General Distribution license allows you to create an unlimited number of applications that use DTWAIN, and distribute the programs in any environment and by any means, royalty-free (commercial, freeware, shareware, within a company, etc.). Also, if the application is an Internet based application, then a General Distribution license must be purchased.
The Toolkit Distribution license is a special license required if your application is a programmer's toolkit or API that will allow programmers to call, either directly or indirectly, DTWAIN functions. Unlike the other Distribution Licenses, the Toolkit Distribution License is subject to royalty fees, where the fee depends on your product's pricing and number of projected sales.
