DynaRithmic TWAIN Library version (DTWAIN) 2.4.0.0 (30-day Demo Version)
Before installing, please read the information on debugging using the DTWAIN library. All other features are enabled in the trial version.
DynaRithmic TWAIN Library (DTWAIN) 2.4.0.0 (Free Version)
The DTWAIN free version has the following limitations.
To summarize, you can acquire only single pages, and only to BMP files if acquiring to a file. If you call a function that is not supported, or call a function with unsupported options, a message box will appear stating that the function is not supported. For the DTWAIN_AcquireFile or DTWAIN_AcquireFileEx functions, the only type that is accepted in the Personal Edition is the DTWAIN_BMP (a Windows BMP) file type. If another type is specified, DTWAIN_AcquireFile(Ex) will return 0 and no acquisition will occur.
There are pre-built applications that have been created with the latest version of the DynaRithmic TWAIN Library. These applications can (and should) be executed to see if your TWAIN device behaves correctly. The most important example is DTWDEMO.EXE, since this example tests many aspects of the TWAIN driver. The test suite examples are included in the DTWAIN Personal and Demo editions. The test suite examples can also be distributed with your application, or to others who would like to see if their device works with DTWAIN. There is absolutely no restriction on who obtains or uses the test suite examples. The examples can be distributed with your application, or you can just download the examples and give them away. The advantage of this is that if you plan on writing an application that will be distributed to many users/customers, you have ready-made DTWAIN applications that the user can run right away to determine if there are any problems running with DTWAIN.
