Emf file is not handled correctly

[muxkin]

What's problem

When I tried to open an emf file and convert it to a jpg file using Pillow, I found that Pillow did not handle the colors in the image correctly. Where it should be white (#FFFFFF), Pillow thought it was (#F8F8F8). I am sure that place is white because this emf image is made by me, and when I open this image with other image viewing software, there is white.

Environment

Windows 10
Python == 3.11.5
pillow == 10.4.0

How to reproduce this situation

Copy figure below into PowerPoint and then save the figure as fig.emf. Use code below and then you can find that the area that should be #FFFFFF has become #F8F8F8.

from PIL import Image
emf_path="fig.emf" 
emf=Image.open(emf_path)
emf.show()

Could you kindly just attach the EMF file itself? If GitHub won't let you attach the file, compress it into a ZIP first.

Sure. I have uploaded a ZIP file.
