Demo Programs

The following demo programs are in separate EXAMPLES subdirectories of the path where you installed your product (such as C:\LEADTOOLS23\Examples\).

The executable files for these examples were compiled with all LEADTOOLS capabilities unlocked. However, for redeployment, some of these capabilities require product-specific unlock keys. Otherwise, if you recompile the examples, the resulting executable files will not have the locked capabilities.

To unlock and redeploy these capabilities, you must purchase an appropriate product license, such as that included with a LEADTOOLS Document/Medical toolkit.

The following demos are available:
