还需要一个dll文件才能用的吧？ 回复 5# waynew
需要 ImageSearchDLL.dll 的吧 回复 7# waynew
谢谢Func _ImageSearchArea($findImage,$resultPosition,$x1,$y1,$right,$bottom,ByRef $x, ByRef $y, $tolerance)
里面参数$resultPositionByRef $x, ByRef $y, $tolerance 是什么意思？ 回复 6# waynew
谢谢{:face (411):} 回复 5# waynew
谢谢{:face (411):} 回复 8# mbdnmt
谢谢需要 ImageSearchDLL.dll 不知道这个找图方法消耗的时间是多少。
