QSORT对位图颜色排序排成了这样，哪位大侠能帮我看看啊

int getCV(TColor color)

{

	int r,g,b;

	r=GetRValue(color);

	g=GetGValue(color);

	b=GetBValue(color);

	return(r*0x00010000+g*0x00000100+b);

}

void qsortbmp(TBitmap *map,int left,int right)

{



	if(left >= right) return;

	int i = left,j = right;

	int temp;

	//int key = a[left];//取首元素为关键值

	int key = getCV(map->Canvas->Pixels[((left + right)/2)%map->Width][int((left + right) / 2/map->Width)]);



	while(i<=j)

	{



		while( getCV(map->Canvas->Pixels[j%map->Width][int(j/map->Width)])>key&&j>left)

			j--;

		while(getCV(map->Canvas->Pixels[i%map->Width][int(i/map->Width)])<key&&i<right)

			i++;

		if(i<=j)

		{

			temp = map->Canvas->Pixels[i%map->Width][int(i/map->Width)];

			map->Canvas->Pixels[i%map->Width][int(i/map->Width)] = map->Canvas->Pixels[j%map->Width][int(j/map->Width)];

			map->Canvas->Pixels[j%map->Width][int(j/map->Width)] = temp;

			i++;

			j--;

		}



	}

	if(left<j) qsortbmp(map,left,j);

	if(right>i)qsortbmp(map,i,right);

}
