TWAIN 2.4 Specification
The Specification describes the interface between an Application and a TWAIN driver. The Errata document identifies problems that may be addressed in the next release. The Features document provides an overview of items that are new to the current TWAIN Specification. The TWAIN.H file is a C/C++ header file used by Application and TWAIN driver developers. The Data Source Manager is the shared library an application uses to find and communicate with TWAIN drivers. The Sample Data Source and Application provide seed code that TWAIN developers may use to start their own projects.
All versions of the TWAIN Data Source Manager interoperate with all versions of TWAIN applications and TWAIN Data Sources from 1.5 to 2.4. Both application and driver developers should install the latest version of the TWAIN DSM, along with their products. Please use the current version below.
