An operator for mouse and keyboard in nodejs.

import cv from '@u4/opencv4nodejs'

//1.下載OpenCV，下載網址：
//   https://github.com/opencv/opencv/releases選opencv-4.12.0-windows.exe
//  windows.exe為免安裝版，下載後解壓縮(不要複製本機檔案，可能因編譯導致檔案格式變更，而無法讓對方編譯)至C:\tools
//  注意須確保路徑有效：
//    C:\tools\opencv\build\include
//    C:\tools\opencv\build\x64\vc16\bin
//    C:\tools\opencv\build\x64\vc16\lib

//2.於package.json內新增opencv4nodejs所需opencv路徑
//   "opencv4nodejs": {
//     "disableAutoBuild": "1",
//     "opencvIncludeDir": "C:\\tools\\opencv\\build\\include",
//     "opencvLibDir": "C:\\tools\\opencv\\build\\x64\\vc16\\lib",
//     "opencvBinDir": "C:\\tools\\opencv\\build\\x64\\vc16\\bin"
//   }

//3.於終端機(PowerShell)視窗內輸入設定參數
//   $Env:OPENCV4NODEJS_DISABLE_AUTOBUILD = "1"
//   $Env:OPENCV_INCLUDE_DIR = "C:\tools\opencv\build\include"
//   $Env:OPENCV_LIB_DIR    = "C:\tools\opencv\build\x64\vc16\lib"
//   $Env:OPENCV_BIN_DIR    = "C:\tools\opencv\build\x64\vc16\bin"
//   $Env:Path = "$Env:OPENCV_BIN_DIR;$Env:Path"

//4.輸出變數確認
//   echo $Env:OPENCV_INCLUDE_DIR
//   echo $Env:OPENCV_LIB_DIR
//   echo $Env:OPENCV_BIN_DIR
//   要能出現路徑才算完成安裝

//5.下載與安裝Python3，開啟自訂設定勾選Add Python.exe to PATH
//   使用cmd輸入以下指令測試:
//   python --version
//   where python
//   要能出現安裝版本與執行檔路徑才算完成安裝

//6.下載安裝Visual Studio Build Tools
//   下載網址: https://visualstudio.microsoft.com/zh-hant/downloads/
//   下載Community版即可
//   安裝時要勾選「使用 C++ 的桌面開發」，其內右側會勾選Windows SDK與MSVC，MSVC內會提供MSBuild

//7.執行npm i -g node-gyp

//8.執行npm i @u4/opencv4nodejs，若msvs有多版本則須指定npm i @u4/opencv4nodejs --msvs_version=2022

console.log(cv.version)
// => { major: 4, minor: 7, revision: 0 }
