Note
As of v21 the LEADTOOLS Multimedia toolkit has been updated to use a seamless license mechanism and any new development must use it. The new licensing mechanism uses L_SetLicenseFile and L_SetLicenseBuffer. For a step-by-step tutorial on a C DLL platform, refer to Add References and Set a License.
The ILMDSKernel2::UnlockModule mechanism is still supported in v21.
