Guten Abend,
Ich habe folgendes Skript: mit dem ich die Grösse eines Bildes anpassen will:
Skript
#include <GDIPlus.au3>
#include <WinAPI.au3>
$sInImage = FileOpenDialog("Bilder",@WindowsDir & "\", "Bilder (*.jpg)", 1 + 4 )
$sOutImage ="C:\Users\Fabian\Pictures\Wallpaper_Cars\19_Resize.jpg"
$iW = @DesktopWidth
$iH = @DesktopHeight
_ImageResize($sInImage, $sOutImage, $iW, $iH)
If @error Then MsgBox(0,"",@error)
; #FUNCTION# =========================================================================================
; Name...........: _ImageResize
; Description....: Resize an image and optionally convert it to the format you want.
; Syntax.........: _ImageResize($sInImage, $sOutImage, $iW, $iH)
; Parameters ....: $sInImage - Full path to the image to resize / convert.
; In types: *.bmp, *.gif, *.ico, *.jpg, *.jpeg, *.png, *.tif, *.tiff
; $sOutImage - Full path where to save the resized / converted image.
; Out types: *.bmp, *.gif, *.jpg, *.jpeg, *.png, *.tif, *.tiff
; $iW - Width to resize image to.
; $iH - Height to resize image to.
; Return values .: Success - Return 1 and @error 0
; Failure - Return 0 and @error 1~5
; @error 1 = In File does not exist

Folgenden Fehler bekomme ich:

Jemand eine Idee, wie man das Problem lösen kann?
