How to Convert CImg to TBitmap?

Question

in my project i am using CImg library, after image processing i want to show my image result in a TBitmap in C++ Builder XE2, please someone tell me how to do that. Thanks.

You can write a processed image to a file using CImg<>.save_bmp() then open it with TFileStream and then load it with TBitmap.LoadFromStream().

As an alternative you can create a memory mapped file or a name pipe then transform HANDLE to FILE*

HANDLE hFile  = CreateFile(...);
int    handle = _open_osfhandle((LONG)hFile, _mode);
FILE*  f      = fdopen(handle, szMode);

and pass it to CImg<>.save_bmp(FILE*) and then load bitmap using THandleStream and TBitmap.LoadFromStream().
