TWAIN Data Source Manager [DSM], compliant with version 2.3 of the TWAIN specification, but may be used with any version of a TWAIN application or TWAIN data source. [Windows] The TWAIN DSM is a shared library named TWAINDSM.DLL. There is a 32bit and a 64bit version of this file. TWAINDSM.DLL is installed in the Windows System directory (normally C:\Windows\System32). If installing the 32bit file on a 64bit system, make sure it ends up in the WOW64 System directory (normally C:\Windows\SysWOW64) The DSM looks for data sources in C:\Windows\twain_32 or C:\Windows\twain_64. Data sources are also shared objects, but they have a .ds extension. ex: datasource.ds The DSM walks the twain_[32|64] directory and LoadLibrary's each .ds file it finds, then uses GetProcAddress to locate the DS_Entry function. The DSM looks for the environment variable, TWAINDSM_LOG, for the location of the log file to write to. If the environment variable is not set, then no log is kept. Here is an example of setting the environment variable from a command prompt: To send to a file: set TWAINDSM_LOG=/tmp/twain.log The source code is documented using the Doxygen documentation system. Please refer to the TWAIN spec from http://www.twain.org for further details on TWAIN. CMake is used to generate the makefiles. You can get a copy of this free from http://www.cmake.org. Or use the provided Visual Studio project file. To prevent hook code from causing an exception on some systems with DEP turned on, link the 32bit version with the /NXCOMPAT:NO flag. Use the TWAINDSM merge module with installations of TWAIN applications and data sources to distribute the TWAINDSM.dll. The 64bit merge module, TWAINDSM64.msm, contains both the 32bit and 64bit versions of the DSM. [Linux] The TWAIN DSM is a shared object named libtwaindsm.so that is installed in /usr/local/lib. The location is the same for both 32-bit and 64-bit systems. There is no provision for running 32-bit TWAIN applications on 64-bit versions of Linux. The DSM looks for data sources in /usr/local/lib/twain. Data sources are also shared objects, but they have a .ds extension. ex: datasource.ds The DSM walks the /usr/local/lib/twain directory and dlopen's each .ds file it finds, then uses dlsym to locate the DS_Entry function. The DSM looks for the environment variable, TWAINDSM_LOG, for the location of the log file to write to. If the environment variable is not set, then no log is kept. Here are some examples of setting the environment variable from a bash shell: To send to a file: export TWAINDSM_LOG=/tmp/twain.log To send to the console: export TWAINDSM_LOG=/dev/stdout The source code is documented using the Doxygen documentation system. There is a file named doc/fhs-2.3.pdf included in this distribution. It is the current filesytem hierarchy standard (FHS). The FHS was adhered to for Linux, but not for Solaris. Please refer to the TWAIN spec from http://www.TWAIN.org for further details on TWAIN. CMake is used to generate the makefiles. You can get a copy of this free from http://www.cmake.org. [Mac OS X] This TWAIN DSM is not intended for use with Mac OS X. This will be addressed in a future version of the TWAIN Specification. TWAIN applications and TWAIN data sources on Mac OS X should use the TWAIN DSM that is delivered with the operating system.
