ImageMagick - Image Comparison

[JoelH]

Hello,

I have successfully used the Image Magick object to convert an image into another format: 

Func _ImageMagick_Convert($infile, $outfile)
local $o_object;
local $rc;


$o_object = ObjCreate("ImageMagickObject.MagickImage.1")
If Not IsObj($o_object) Then
Return 0
endif


$rc = $o_object.Convert($infile, $outfile)


Return 1
EndFunc

I now wish to use Image Magick's compare functionality to obtain an 'overall image distortion'. I have found the code for this here: 

http://www.imagemagick.org/script/compare.php

However, I am unable to get the code to work:

Func _Compare_Image($fileOne, $fileTwo, $result)
local $o_object;
local $rc;


$o_object = ObjCreate("ImageMagickObject.MagickImage.1")
If Not IsObj($o_object) Then
Return 0
endif


$rc = $o_object.Compare("-metric", "PSNR", $fileOne, $fileTwo, $result)


Return $rc
EndFunc




$test = Call("_Compare_Image", "Sample One.png", "Sample Two.png", "Result.png")


ConsoleWrite($test)

I am not sure how to pass the -metric PSNR method.  Can anyone help?
