查找文字返回全部结果 - FindStrFromPtrAll

函数简介

从指定图片中查找文字并返回全部匹配结果。

接口名称

FindStrFromPtrAll

DLL调用

long FindStrFromPtrAll(long instance, long source, string str, string colorJson, string dict, 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长整数型源图片对象的指针。
str字符串待查找的字符串,可以是字符串组合,比如"str1|str2|str3",中间用"|"来分割字符串
colorJson字符串颜色模型配置字符串,用于限定识别区域的颜色范围,格式说明见 颜色模型说明 - ColorModel。JSON格式示例:[{"StartColor":"3278FA","EndColor":"6496FF","Type":0}];简化格式示例:3278FA-000000|6496FF-2020203278FA~6496FFFF0000|00FF00
dict字符串字库名称,为空时搜索所有字库;多个字库用 | 分割,如 dict1|dict2
matchVal双精度浮点数匹配值。

返回值

返回值说明
(返回值)字符串指针地址,返回JSON数组格式的全部匹配结果,如:。
json
[
    {
        "MatchVal": 0.85,
        "MatchState": true,
        "Index": 0,
        "Angle": 45.0,
        "X": 100,
        "Y": 200,
        "Width": 100,
        "Height": 100
    },
    {
        "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。

返回的字符串指针需调用 FreeStringPtr 释放内存。
