Do you need autoit to get the width and height of an image, or do you need the image width and height to add an image into a script?

if it's the latter case, then you can open the image in a paint program, most will give you the width and height.

To have autoit get the with and height, you might have to use a color of reference to find the top left corner add the coordinents to a variable, then find the top right corner and add to another variable and there is your width, then find your bottom left corner and add to a 3rd variable, the first and 3rd variable become the image height.

if it's from a web page, then you can probably have autoit search the source file for the image width and height as that info is in the html code.

im doing this.. but the msg box with the values is not displayed...

i need autoit to open an image (@DesktopDir & "\screenshot.jpg") then display its dimensions for example... 1024 by 768

#include <GDIPlus.au3>
#include <WinAPI.au3>

$hImage = @DesktopDir & "\screenshot.jpg"

_GDIPlus_ImageGetDimension($hImage)


Func _GDIPlus_ImageGetDimension($hImage)
    Local $aSize[2], $aResult

    $aResult = DllCall($ghGDIPDll, "uint", "GdipGetImageDimension", "hwnd", $hImage, "float*", 0, "float*", 0)
    If @error Then Return SetError(@error, @extended, -1)

    $GDIP_STATUS = $aResult[0]
    If $GDIP_STATUS Then Return -1

    $aSize[0] = $aResult[2]
    $aSize[1] = $aResult[3]
    MsgBox(1,"test",$aSize[0]&" - "&$aSize[1])

    Return $aSize
EndFunc

#include <GDIPlus.au3>

; Initialize GDI+ library
_GDIPlus_Startup()

$hImage = _GDIPlus_ImageLoadFromFile(@DesktopDir & "\screenshot.jpg")

$iY = _GDIPlus_ImageGetHeight($hImage)
_GDIPlus_ImageDispose($hImage)

MsgBox(0, "", $iX & "x" & $iY)

; Shut down GDI+ library
