		ImageDataPtr& operator= (ImageDataPtr& p) {
			if(ptr != p.ptr) {
				dispose();
				ptr = p.getPtr();
				count = p.getCount();
				++*count;
			}
			return *this;
		}

ImageDataPtr copyImage(ImageData* bitmap, Vec4 box);



ImageDataPtr lenaImgPtr(c.decode(lena));


/* this line cause a no match error because copyImage returns ImgDataPtr
*  however, there is only one "=" operator in ImgDataPtr which takes ImgDataPtr&
*/
lenaImgPtr = c.copyImage(lenaImgPtr.getPtr(), Vec4(0,0,400,400));


this kind of usage was valid for mscv and seems correct to me as well :) saves me from writing same thing
