天黑版opencv_ahk.dll使用（改变了调用方式，优化速度…）

相关文件：https://wwz.lanzouw.com/iAkK803eaaud

cv2.ahk和log.ahk来自社区群友zzZ…

可以用文件中的天黑版的v2h版ahk运行。

示例：作为调色板的跟踪栏（由天黑请闭眼提供）

#Dllload lib
#DllLoad opencv_ahk.dll
#include <cv2>
#include <log>
SetWorkingDir A_ScriptDir
Persistent

;初始化opencv模块
cv := ObjFromPtr(DllCall('opencv_ahk.dll\opencv_init', 'ptr', DllCall(A_AhkPath '\ahkGetApi', 'ptr'), 'cdecl ptr'))

img := cv.Mat(400, 400, cv2.CV_8UC3, [0, 0, 0])
cv.namedWindow('image')

;创建一个改变颜色的轨迹栏
cv.createTrackbar('R','image', 255, rr := getpos.Bind("r"))
cv.createTrackbar('G','image', 255, gg := getpos.Bind("g"))
cv.createTrackbar('B','image', 255, bb := getpos.Bind("b"))

getpos(t, pos){
    static r := 0, g := 0, b := 0
    %t% := pos
    img.setTo(cv.MAT(1, 3, cv2.CV_8UC3, [b, g, r]))
    cv.imshow('image', img)
}

cv.waitKey()
cv.destroyAllWindows()
