any way to get an image's dimensions (pixels in X & Y direction) ?

[rossnixon]

Is there any way to get an image's dimensions (pixels in X & Y direction) ?
I can see the dimensions using one of the Windows File Explorer, details view, extra columns.

My images are pretty much all the same size for a 'session', so this isn't too important.
I can always 'hard code' this into each instance of my script and just put the dimensions in the filename.

Check in help file _GDIPlus_ImageGetDimension(). There is also an example.

Alternatively, you can use _WinAPI_GetBitmapDimension (see help file).  But _WinAPI_LoadImage is much more restrictive in terms of file types you can read.

Unfortunately this doesn't work with JP2 (jpeg2000) files.

Tried but output dimensions using the example image showed as 0,0 instead of 400,400.

Local $aDim =  _GetImageDimensions("C:\Program Files (x86)\AutoIt3\Examples\GUI\logo_autoit_210x72.gif")
ConsoleWrite($aDim[0] & "x" & $aDim[1] & @CRLF)

Func _GetImageDimensions($sPath)
    Local $sFile = StringTrimLeft($sPath, StringInStr($sPath, "\", 0, -1))
    Local $sDir = StringTrimRight($sPath, (StringLen($sPath) - StringInStr($sPath, "\", 0, -1)))
    Local $oShellApp = ObjCreate("shell.application")
    Local $oDir = $oShellApp.NameSpace ($sDir)
    Local $oFile = $oDir.Parsename ($sFile)
    Local $aDimension[2]
    $aDimension[0] = $oFile.ExtendedProperty("System.Image.HorizontalSize")
    $aDimension[1] = $oFile.ExtendedProperty("System.Image.VerticalSize")
    Return $aDimension
EndFunc   ;==>_GetProperty

Thanks ioa747 !
That worked fine. It helped when I added the /console switch; which I don't recall using before.

I was hoping this would also work with jpeg2000 files, but it doesn't.
Program output dimensions is just x, instead of 1611 and 1450 as in my jp2 image.

Looks like you would need to convert it beforehand and use one of the method shown above...
