Considering Development Systems

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 v15/16 libraries provide both ANSI and UNICODE support in the same dll. This is not the case for DICOM:

LEADTOOLS Version 15 supports UNICODE development only.
LEADTOOLS v16 also 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.
