The LEADTOOLS C DLL is designed as standard Windows Dynamic Link Libraries. You should be able to use the LEADTOOLS C DLL with any compiler that supports Windows DLL calls. This topic explains some of the options.

Calling functions from a C/C++ program:

Most of the LEADTOOLS example programs and all of the documented code examples are for Windows programs written in C/C++. You can use LEADTOOLS as explained in Using LEADTOOLS with Your C/C++ Compiler.

Calling C DLL functions from Delphi:

You can call LEADTOOLS C DLL functions from a Borland Delphi program. An example is provided in the DELPHI subdirectory.

Using C DLL functions with the LEADTOOLS ActiveX:

You can use the LEADTOOLS C DLL functions to work with images in the ActiveX controls. To access the image in a control, you can use the L_GetControlBitmap and L_SetControlBitmap functions, which are documented in the LEADTOOLS ActiveX help file.

Most LEADTOOLS libraries provide both ANSI and UNICODE support in the same dll. This is not the case for DICOM support. LEADTOOLS provides both UNICODE-only and ANSI-only versions of the C DLL DICOM dlls. For information on the required dll name and import library, please refer to Files To Be Included With Your Application.
