ImageMagick Object

Image Processing in AU3 - IMAGEMAGICK

I saw someone mentioning IMAGEMAGICK in the support site,

and I remembered it has a huge number on command line options.

The later version has as well an COM object, that exposes all cmd line options via the object.

IMAGEMAGICK - COM Object

Perfect for AU3 wouldn't you say.

There are about 200 cmd line options. IMAGEMAGICK - Command line Options

This will get you all started.

Dim $img
Dim $ret

; Initialize error handler
$oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

$img = ObjCreate("ImageMagickObject.MagickImage.1")

$ret = $img.Convert("C:Tempbill_meets_gorilla_screen.jpg", _
        "-resize", "320x200", _
        "-sepia-tone", "70%", _
        "-format", "gif", _
        "C:Tempbill_meets_gorilla_screen_NEW.gif")


Func MyErrFunc()
$HexNumber=hex($oMyError.number,8)
Msgbox(0,"COM Error Test","We intercepted a COM Error !"     & @CRLF & @CRLF & _
             "err.description is: " & @TAB & $oMyError.description  & @CRLF & _
             "err.windescription:"   & @TAB & $oMyError.windescription & @CRLF & _

             "err.helpcontext is: " & @TAB & $oMyError.helpcontext _
            )
SetError(1) ; to check for after this function returns
Endfunc

Const $ERROR_SUCCESS = 0

Dim $img
Dim $info
Dim $msgs
Dim $elem
Dim $sMsgs

; Initialize error handler
$oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

; This is the simplest sample I could come up with. It creates
; the ImageMagick COM object and then sends a copy of the IM
; logo out to a JPEG image files on disk.
;
$img = ObjCreate("ImageMagickObject.MagickImage.1")
;
; The methods for the IM COM object are identical to utility
; command line utilities. You have convert, composite, identify,
; mogrify, and montage. We did not bother with animate, and
; display since they have no purpose in this context.
;
; The argument list is exactly the same as the utility programs
; as a list of strings. In fact you should just be able to
; copy and past - do simple editing and it will work. See the
; other samples for more elaborate command sequences and the
; documentation for the utility programs for more details.
;
$sMsgs = $img.Convert("logo:","-format","%m,%h,%w","logo.jpg")
;
; By default - the string returned is the height, width, and the
; type of the image that was output. You can control this using
; the -format "xxxxxx" command as documented by identify.
;

    
MsgBox (0,"info: ","Return = " & $sMsgs)



Func MyErrFunc()
$HexNumber=hex($oMyError.number,8)
Msgbox(0,"COM Error Test","We intercepted a COM Error !"     & @CRLF & @CRLF & _

@Bert

Thanks and happy scripting with your functions !!

@Nobbe

Thanks for your contribution.

I had a look at the Nconvert tool. But it does not seem to be for free all the way. Only for personal use.

Nevertheless it looks a powerfull tool as well.

Why did you decide to move to Nconvert from ImageMagick ?

regards,

ptrex

Cool. Now you have made my problem even easier! Thanks, this is alot better than the way I was doing it :whistle:

You should make some UDF's for this!

When I tested this app, I used command line.

If I can remember it, ImageMagick needs to be installed and assigns a lot of system variables. Is there a way that doesn't need installing?

My target was to be able to carry a compiled script with me (for instance, on a CD or USB key) and run it in any machine, without having to install ImageMagick first.

So it would be like using ImageMagick's files in the same directory as my script or in an addon folder or something...

But COM Objects need app registration in the operating system and so on, am I right?

the dll has to be registered, but this is an easily handled scenario -- assuming permissions aren't a problem.


Reading the help file before you post... Not only will it make you look smarter, it will make you smarter.

@Bert

Good to see that you are picking this up.

Because it's a long way, when you compaire all the options IMAGEMAGICK has.

But that's what holidays are good for, correct :)

So the page you gave us has all the "switches" for the actual image manipulation? So i could call 1 function, to do an umpteenth of those things? Maybe using a number? (2,4,8,16...) to tell what switches? hmmm.... but then you've got trouble with the values... maybe call one function to manipulate the the image, with that specific value.... I'm lost now :) Could you give me a pointer on how to go about this? And it doesn't help that Dial-up sucks... :P

Is someone can send me the ImageMagickObject.dll

because i don't know how to made it

Thanks in advance

How about this for a funky way to call the function?

Using Arrays! YAY!

So Say we had

$aArray[0] = Function Name

$aArray[1] = Function Parameter

_ImageMagick ("COMPARE", $aArray, $pInput, $pOutput)

I don't know how effective it would be, a downside is it does heavily complicate things... :)
