帮忙看一下那个inc inc(pQtZzMCU,Y_in_MCU*64);它到底给谁加1?还是两个都加1还是将Y_inMCU*64后再加1? 同样inc(pQtZzMCU,(Y_in_MCU+U_in_MCU)*64);也看不懂。麻烦高手帮忙解答一下,十分感谢!!!!!!!!!!!!!!!!! 原程序: 1: //红色分量 begin H:=SampRate_U_H; VV:=SampRate_U_V; buf:=@U; pQtZzMCU:=Pint(@QtZzMCUBuffer); inc(pQtZzMCU,Y_in_MCU*64); end; 2: //蓝色分量 begin H:=SampRate_V_H; VV:=SampRate_V_V; buf:=@V; pQtZzMCU:=Pint(@QtZzMCUBuffer); inc(pQtZzMCU,(Y_in_MCU+U_in_MCU)*64); end; |
