查找图片1 - FindImageFromPathAll

函数简介

在指定图片中查找指定图像的所有匹配位置,源图与模板均通过文件路径指定,返回全部匹配结果。

接口名称

FindImageFromPathAll

DLL调用

long FindImageFromPathAll(long instance, string source, string templ, string deltaColor, double matchVal);

参数说明

参数名类型说明
instance长整数型OLAPlug对象的指针,由 CreateCOLAPlugInterFace 接口生成。
source字符串源图片的路径。
templ字符串模板图片的路径,可用 | 分隔多图,如 "test.bmp|test2.bmp|test3.bmp"默认任一模板不存在或加载失败时整次返回空;可通过 SetConfigByKey 设置 MultiTemplateAbortOnInvalidImage=false 跳过无效模板继续匹配。
deltaColor字符串颜色差值,格式为"RRGGBB",如"101010"。
matchVal双精度浮点数相似度,如0.85,最大为1。

返回值

调用方式返回值说明
SDKMatchData/MatchResult 列表(Python 为 list[dict]全部匹配结果;空列表表示未找到
SDK(火山)MatchDataList结构化结果列表
SDK(易语言)整数型 + retDataMatchData 数组)返回找到数量,结果写入 retData;内部为 GetStringFromPtr + OL_获取MatchDataAll;可选 rawstring 拿原始 JSON
