Extract Icon into graphic file

[shx]

I'm trying to create a graphic file, by extracting an icon from an EXE in saving it as a JPEG

it seems to me that the steps are as follows.

• Get a handle of the icon that you wish to use.

• convert that somehow into a graphic image.

• Save the graphic to a file.

I understand that the method to use has to do with the GDI functions. However, if someone can give me an example of the steps, the code, it would really be appreciated. Thank you

The examples that I have found by searching the forum generally show how to use an icon within a GUI control.

I don't see how this would work for me. Thanks again

eerm, give me a minute

You want to make an application to do that? or you want to do it just once?

If you want to do it just once, you could use 'reshack.exe'. It lets you save all the icons there is in an exe. Then use some image software to convert it to jpeg, like IrfanView.

yeah, icons arent like bitmaps. Thats probably the reason why they gave them 2 different names.

You can extract with GDIPlus:

#include <GDIPlus.au3>
#include <IconChooser.au3> ;http://www.autoit.de/index.php?page=Thread&postID=31304#post31304

$Icon = _ChooseIcon()
If $Icon[0] = "" Then Exit MsgBox(0, 'Exit', "No Icon chosen")
$Ret = DllCall("shell32","long","ExtractAssociatedIcon","int",0,"str",$Icon[0],"int*",(-1*$Icon[1])-1)
$hIcon = $Ret[0]
_GDIPlus_Startup()
        $pBitmap = DllCall($ghGDIPDll,"int","GdipCreateBitmapFromHICON", "ptr",$hIcon, "int*",0)
        $pBitmap = $pBitmap[2]
_GDIPlus_ImageSaveToFile($pBitmap,"D:\Test.png")
_GDIPlus_ImageDispose($pBitmap)
_GDIPlus_Shutdown()
_WinAPI_DestroyIcon($Ret[0])
;~ MsgBox(0, "#" & $Icon[1], @error)

GdipCreateBitmapFromHICON

Hey! That one isn't in the helpfile (Should be added, though)

Look at nice similar example here

You will nedd to use ExtracIconEx API to get icon from EXE file,

search forum for examples.

ProgAndy, Thanks for getting back to me and your help.

<IconChooser.au3> ;http://www.autoit.de/index.php?page=Thread&postID=31304#post31304

I clicked on the link but could not understand the German.

Where do I get the include file?

I'm kind of a newbie so please excuse if the answer is obvious.

The Include is in the Spoiler Click on "Anzeigen" to open it Then you can see "AutoIt-Quellcode"

Thanks for your help.

This also was my post. Actually there was a problem with my browser and I ended up double posting. My apologies.

I don't understand where the include iconchooser.au3 is coming from.

I did look at Extracticonex and I know it is used to create an array of handles for icons. That step I understand. But I am a beginner and there is very little in the help file or the forum that take those handles and use it to save the icon as a graphic file like a jpg or png.

O.K.

I got it to run. Now I need to figure out what it is doing.

ProgAndy, your help is very much appreciated.

I'm a beginner so maybe my next question is obvious but when the file is saved as a png the background looks black. Why is that? does it have to do with transparency?

My Script consists out of 2 parts.

1) <IconChooser.au3> is a Dialog to Choose the Icon in a DLL

It Returns the negative Index number Starting with -1

2) ExtractAssociatedIcon loads the Icon to memory, but needs 0 based, positive Index, so I convert it ($index*(-1))-1)

GdipCreateBitmapFromHICON creates a GDIplus-Bitmap out of the Icon. The Transparency SHOULD be saved, too ( works for me)

Then the Image is saved with GDIplus as png, normally WITH transparecy.

How do you open the png? With MSPaint? This app doesn't support transparency.
