Files to be Included with your Application

Note: You may not copy or redistribute any of the following files without obtaining the proper license. In some cases, the license is included with your initial purchase of LEADTOOLS. In other cases, you must obtain a license from a third party or enter into a royalty agreement with LEAD to obtain the proper license. For these special licensing situations, see the notes below accompanying the specific file.

TWAIN support. LTTWN is the LEADTOOLS TWAINSupport DLL.

LEADTOOLS TWAIN toolkits support versions v1.9 and v2.x of the TWAIN specification. For more information, refer to Setting which TWAIN Specification Version to use.

Some scanner drivers are only supported in a 32-bit environment and cannot interact with a scanner in a 64-bit process application. LEAD provides the LEADTOOLS THUNK utility to work around this limitation. Note that if this utility is used, additional files need to be included with your application when distributing it. For more information, refer to the Using the LEADTOOLS THUNK Utility with TWAIN topic.
