本程序通过使用SetDBIbits,BitBit,IPicture,SetPiexl等多种图片读取方式来计算相同图片读取时所以需的时间,从而体现出不同贴图方式上在时间的差异-this procedure through the use of SetDBIbits, BitBit, IPicture, SetPiexl read so many pictures to calculate the same way when you read Photo Therefore, it takes time, so as to realize the different textures in the way time difference! !
