ApplicationLog('Zones inverted found: '+ IntToStr(RectsCount));

// For each zone get the left, top, right and bottom coordinates

For I:=0 to RectsCount-1 do

begin

 X1:= ImgRectGetLeft(RectsList,I);

 Y1:= ImgRectGetTop(RectsList,I);

 X2:= ImgRectGetRight(RectsList,I);

 Y2:= ImgRectGetBottom(RectsList,I);

 // Log a message 

 ApplicationLog('Zone #'+IntToStr(i)+' : '+IntToStr(X1)+','+IntToStr(Y1)+','+IntToStr(X2)+','+IntToStr(Y2));

end;

// Free the zones list from memory

ImgRectsFree(RectsList););
