Are you trying to convert the above C++ code into DLL API
code? If yes, you can refer to our LEADTOOLS API Help file. Our LEADTOOLS Class
Library programming interface and our API mostly use similar functions names
and declarations. Actually our LEADTOOLS Class Library wraps around the API functions.


For example, the CreateAlphaBitmap function calls the L_GetBitmapAlpha internally, and so on.

If you search for the API equivalent for a C++ Class Library function and you can't find it, tell us which one it is and we will help you.
