    Add-Type -AssemblyName System.Windows.Forms
    [System.Windows.Forms.Screen]::AllScreens

    BitsPerPixel : 32
    Bounds       : {X=2560,Y=255,Width=1920,Height=1080}
    DeviceName   : \\.\DISPLAY1
    Primary      : False
    WorkingArea  : {X=2560,Y=255,Width=1920,Height=1040}

    BitsPerPixel : 32
    Bounds       : {X=0,Y=0,Width=2560,Height=1440}
    DeviceName   : \\.\DISPLAY2
    Primary      : True
    WorkingArea  : {X=0,Y=0,Width=2560,Height=1400}

  • 调用 Powershell 执行 magick 命令, 将选中的2张图片合并为一张大图

    magick.exe convert -size 757x388 -strip xc:none .\1.jpg -geometry +0+0  -composite .\2.jpg -geometry +369+0 -composite  c2.jpg
    # 总宽度 x 总高度     第一张图的起始位置 0 x 0     第二张图的起始位置  +x+y
