You will need EnTransf.pas added to you project along with EnTransf.hpp added to your header file.

TBrightnessTransform *Transform = new TBrightnessTransform;
Transform->Percent = 60; //Less than 100 makes darker: //greater than 100 makes lighter
Transform->Apply(ImageScrollBox->Graphic);
delete Transform;

((TRubberBandMouseHandler*)ImageScrollBox->MouseHandler)->ShowGrips = true;

Add the file EnJpgGr.pas to you project and #include "EnJpgGr.hpp" in you header file.
