Converting Client Coord to Window Coord

7 posts in this topic

#1 ·  Posted (edited)

I've got some coordinate from IE which is relative to browser's client area. However, it seems that _ScreenCapture_CaptureWnd() is expecting window-relative coordinate. How can I convert my client area relative coord to the one _ScreenCapture_CaptureWnd() needed?

BruceCopperField,

Have you looked through the Help file?

If you search for "client screen", you will find _WinAPI_ClientToScreen and its complement _WinAPI_ClientToScreen. :evil:

Read the relevant pages carefully, it is not quite as straightforward to use as you might think. ;)

Yes, I've tried that. But it is converting from client area relative to SCREEN relative - not active window relative.

Posting 2 3! threads on very similar (identical?) topics is not very clever. I have answered you question in the other thread. To convert it to the "active window relative" you just need the position of the active window:

$nScreenX = 55
$nScreenY = 234

$aPos = WinGetPos ("[active]")

$nActiveX = $nScreenX - $aPos[0]
$nActiveY = $nScreenY - $aPos[1]

MsgBox (0, "Result", @TAB & "||" & @TAB & "Screen" & @TAB & "||" & @TAB & "Active window" & @CRLF & "X" & @TAB & "||" & @TAB & $nScreenX & @TAB & "||" & @TAB & $nActiveX & @CRLF & _
"Y" & @TAB & "||" & @TAB & $nScreenY & @TAB & "||" & @TAB & $nActiveY)

BruceCopperField,

Sorry, misunderstood the _ScreenCapture function you were try to use.

Which leads on to to: if you only want to capture part of the client area, why use _ScreenCapture_CaptureWnd, which is designed for a whole window? Why not use _ScreenCapture_Capture which takes screen coords - which you can get via the functions I mentioned above?

A way I converted my known coordinates in window mode to client mode was open AutoIt Window Info (AIWI), change coordinate options to window, click on desired window and move mouse somewhere on window, use alt tab to select AIWI, check mouse position and write down somewhere, change coordinate options to client, alt tab to active window then alt tab back, check second mouse position. Then use the 2 positions to find out difference in the two and apply difference to code. Crude, but for a simple fix this should work.
