匹配绑定窗口图片3 - MatchWindowsFromPath

函数简介

匹配符合模板图片的坐标,模板通过文件路径指定,返回相对绑定窗口坐标,默认返回最优结果。

接口名称

MatchWindowsFromPath

DLL调用

long MatchWindowsFromPath(long ola, int x1, int y1, int x2, int y2, string templ, double matchVal, int type, double angle, double scale);

参数说明

参数名类型说明
ola长整数型OLAPlug对象的指针,由 CreateCOLAPlugInterFace 接口生成。
x1整数型查找区域的左上角X坐标
y1整数型查找区域的左上角Y坐标
x2整数型查找区域的右下角X坐标
y2整数型查找区域的右下角Y坐标
templ字符串模板图片的路径,可以是多个图片,如"test.bmp|test2.bmp|test3.bmp"
matchVal双精度浮点数相似度,如0.85,最大为1
type整数型匹配类型:1-灰度匹配(速度快);2-彩色匹配;3-透明匹配;4-透明彩色权重匹配;5-普通彩色匹配
angle双精度浮点数旋转角度,每次匹配后旋转指定角度继续匹配,角度越小匹配次数越多时间越长,0为不旋转速度最快
scale双精度浮点数窗口缩放比例,默认为1,可通过GetScaleFromWindows接口获取

# 原生返回 JSON 字符串指针,可用 ParseMatchImageJson 解析

返回值

字符串指针,返回JSON格式的匹配结果。多图识别时Index字段标识是第几个图片返回的结果,索引从0开始。DLL调用返回字符串指针地址,需要调用 FreeStringPtr 接口释放内存。

返回数据格式:

json
{
    "MatchVal": 0.85,
    "MatchState": true,
    "Index": 0,
    "Angle": 45.0,
    "X": 100,
    "Y": 200,
    "Width": 100,
    "Height": 100
}
字段名类型说明
MatchVal浮点数匹配相似度。
MatchState布尔是否匹配成功。
Index整数结果索引(从 0 开始)。
Angle浮点数匹配角度。
X整数X 坐标。
Y整数Y 坐标。
Width整数宽度。
Height整数高度。

注意事项

  • x1、y1、x2、y2都传0时,将搜索整个窗口客户区
  • 返回的坐标是相对于绑定窗口客户区的坐标
