请教获取固定字符坐标的问题
用AU3在屏幕上获取指定字符的坐标。例如我的屏幕上有一大堆A B C D ４个选项，我想取这４个字母的坐标，这个可以实现吗？ A B C 有时候是字符 也有时候我们看到的 A B C 是图片请楼主说详细一些哦 比如是什么 地方的ABC 你想要实现什么 基本上很难做到，想弄这个费时费力，不如另寻捷径 阿福的纯AU3找图 速度很不错以下为全部代码 可以根据自己需要精简 Search.Bmp是需要找的图 自己事先截好 保存为位图格式 $aPosMsg是返回的坐标信息
图方便的话就是大漠插件 调用格式他的帮助里面都有。#include <GuiConstantsEx.au3>
