Demo Programs

Demo programs showcase LEADTOOLS core features, and demonstrate some of the simple, yet powerful applications that can be produced with LEADTOOLS.

Demo Executables

LEADTOOLS demo executables show and allow you to manipulate basic toolkit functionality through a simple user interface. Demo executables are found on the installation path in the appropriate platform subdirectory of the \BIN\ folder (for example: <LEADTOOLS_INSTALLDIR>\Bin\CDLL\Win32).

Demo Project Source Code

LEADTOOLS includes complete demo project source code for hundreds of LEADTOOLS features, (including those shown in demo executables). This enables you to see, manipulate, and copy demonstrated program functionality. Demo project source code is found on the installation path in the appropriate platform subdirectory of the \EXAMPLES\ folder (for example, <LEADTOOLS_INSTALLDIR>\Examples\Ltmf\Cpp\capture).

Refer to Example Programs and Demos for a table listing the different DirectShow demo source code projects and executables available.
