Different sizing?

[RixInGithub]

In a previous issue #11, I said this:

Ok, yeah, all the icons for system libraries got moved to a new location in Windows 10 1903: https://superuser.com/questions/1480268/icons-no-longer-in-imageres-dll-in-windows-10-1903-4kb-file

I'm not sure if the new DLLs actually embed a reference to the .mun files, or if the system implicitly looks up the right file based on the DLL name. If the latter is true, there's not much icoextract can do other than make a guess.

My version of the C:\Windows\SystemResources\imageres.dll.mun file starts off with the magic bytes of "MZ", typically an executable or a .DLL

And with my second edit, I said, that I needed a different size of the icon. I want the icon to be 48x48 pixels in size, and here's the snippet:

import icoextract as icns

ext = icns.IconExtractor(r"C:\Windows\SystemResources\imageres.dll.mun")
ext.export_icon("foldIcon.ico", num=3)
print("Icon extracted successfully.")

foldIcon.ico is currently 16x16 pixels in size, but I want it to be a 48x48 icon, to be as an PIL image. Can some help me?

This is working fine for me when looking at SystemResources on Windows 11.

.ico files are multi-image files, and each "group icon" will usually contain multiple sizes and bit depths. You'll definitely want to use a toolchain that's aware of this: for example, the Pillow library lets you extract specific sizes using the save() method: see https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#ico

No, I meant the PIL part as if for the image to be an Image object.

Doe something like this work? This is how I do resizing in the exe-thumbnailer script, though I suppose the im.size = ... trick isn't mentioned in that doc page. I don't quite remember how I found out about this, perhaps it was just experimentation.

from icoextract import IconExtractor
from PIL import Image

extractor = IconExtractor('imageres.dll.mun')
data = extractor.get_icon(num=3)
im = Image.open(data)  # create a PIL image from the .ico in memory
im.size = (48, 48)
im.save("result.png", "PNG")

WOW, thanks for the help! :)
