但价值和计数属性保持不变的大光栅文件。
But the value and count attributes remained the same with the big raster file.
要记住在定时器开始后重设间隔属性会导致当前计数为0。
Keep in mind that resetting the Interval property after the timer has started will reset the current count back to zero.
如果您愿意接受一些条件的话，这是可行的。但除了不需要定义计数器属性本身之外，其他工作省不了多少。
You can do this if you are willing to accept some compromises, but other than avoiding the definition of the counter property itself, you wouldn't really save much.
