查找指定颜色范围坐标 - FindMultiColorList ​

函数简介 ​

查找绑定窗口指定区域内符合指定颜色范围的所有颜色点，返回坐标列表。

接口名称 ​

FindMultiColorList

DLL调用 ​

long FindMultiColorList(long ola, int x1, int y1, int x2, int y2, string colorList, string pointColorList, double sim);

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。
colorList字符串颜色模型配置字符串，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~6496FF。
pointColorList字符串点阵颜色列表，格式说明见 点阵颜色列表格式说明。
sim双精度浮点数相似度，取值范围 [0~1.0]。

# 原生返回 JSON 坐标数组指针

返回值 ​

返回值说明
（返回值）长整数型：返回坐标点列表的JSON字符串指针，格式为 [{"x":1,"y":2},{"x":2,"y":1}]。失败返回0。

注意事项 ​

项目说明
释放内存返回的字符串指针需调用 FreeStringPtr 释放内存。
搜索范围x1, y1, x2, y2 全传0时查找整个窗口客户区。
