Hello dears. In GrabCutSelection sample,after getting GrabCutSelection results of SelectionMask(gc.getSelectionMask(ImageEnView1.SelectionMask;), I want to add or cut off some parts to the selection through mouse action (draging the mouse with ctrl of shift). Test showing I can add new parts to the existed selection of gc results by mouse action with shift. but I can't cut off parts from the selection ofgc.getSelectionMask by mouse action (draging with ctrl).
Yes. You can add new parts to the custom selection by draging mouse with shift, but you can not cut off parts form the custom selection by draging mouse with ctrl.
