Ahk v1 Using CaptureScreen by Linear Spoon

[PuzzledGreatly]

I'm having trouble using this code by Linear Spoon to capture an active Window on my second monitor. I believe that the following should capture the active window to a file:

Code: Select all

CaptureScreen(1,0,"D:\test.png")

The problem is if the target window is full-sized and on my second monitor the bottom of the image is truncated - as if the taskbar were present when it is not. Does anyone know how to get a screen shot of a maximized window on a second monitor or is there a limitation? Thanks

I'm not familiar with the CaptureScreen() function, and I know nothing about multiple displays, but... Just a thought... could it be a ppi (resolution) issue?

If that window is maximized, you can try:

Code: Select all

CaptureScreen("-1920, 0, 0, 1080", 0, A_ScriptDir "\test987.png")

This works on my 1920x1080 second monitor to the left on my 1st monitor.
You can also use WinGetPos and adjust for dpi setting and borders.

Thanks for the replies, I'm not using any scaling on this machine. The code:

Code: Select all

CaptureScreen("-1920, 0, 0, 1080", 0, A_ScriptDir "\test987.png")

Gave me a black screenshot. I tried:

Code: Select all

CaptureScreen("1920, 0, 0, 1080", 0, A_ScriptDir "\test987.png")

without the " - " but failed to save the file. I've tried using WinGetPos and adjusting for W10's borders but CaptureScreen always ends up cropping the bottom off the image unless I take screenshot of the entire desktop which I don't want.

well, not using CaputreScreen but this worked for me

Code: Select all

WinGetActiveStats, OutTitle, OutW, OutH, OutX, OutY
fileName := A_Desktop "\test.png"
if !pToken:= Gdip_Startup()
{
	MsgBox, 131088, , Gdip not loaded
	ExitApp
}
pBitmap := Gdip_BitmapFromScreen(OutX "|" OutY "|" OutW "|" OutH)
Gdip_SaveBitmapToFile(pBitmap, fileName)
Gdip_Shutdown(pToken)
Run, % fileName
return
