Hi,
using Delphi, I can create an instance of TImageEnProc:
proc := TImageEnProc.CreateFromBitmap(bmp);
or
proc := TImageEnProc.create(nil);
How can I create an instance of TImageEnProc with C++? Everything I tried didn't work.
Thank you for any help

Hi Bernhard
My C++ is not great, but I would have thought you'd need to pass a TComponent class, e.g.
TImageEnProc *proc = new TImageEnProc(Self);

Hi Nigel,
Thanks for the prompt reply.
Of course I tried this line and the compiler aborted with the error message:
Delphi-style classes must be allocated with 'new'
Then I tried
TImageEnProc *proc = new TImageEnProc;
This works with TIEBitmap, for example, but not with TImageEnProc. The compiler aborted with:
no matching constructor for initialization of 'Imageenproc::TImageEnProc'
Next I tried:
TImageEnProc *proc = new TImageEnProc(NULL);
Compiler refused work and responded: call to constructor of 'Imageenproc::TImageEnProc' is ambiguous
Now I've tried something else:
TIEBitmap *Quelle = new TIEBitmap;
TImageEnProc *proc = new TImageEnProc(Quelle);
And so it finally worked!
Should that be mentioned in the help for the class?

Hi Bernhard
It should be the same:
TImageEnProc proc = TImageEnProc->create(NULL);
