I'd like to programmatically make a selection and crop it. I prefer making a selection in a circle. I tried using SetSelectionGripStyle and SetLayersGripStyle but without result. It seems there is no rectangle for selection set when using these functions.
ImageEnView->SetSelectionGripStyle(clWhite, clWhite, bsSolid, 5, true, iegsCircle);
ImageEnView->SetLayersGripStyle(clBlack, clWhite, bsSolid, 5, iegsCircle);
Below you find the result I prefer.
Can you please help me out? Thank you in advance.
