Image aspect ratio morphed/incorrect

Hi @tobire the Kindle only handles Grayscale PNGs correctly. Your PNG has an 8bit color/alpha profile. This is probably something you can specify in your Python code when generating the PNG. Alternatively you can convert the image using pngcrush: pngcrush -c 0 dash.png.

Let me know if that works!

It's kind of working now.
The image is not as stretched anymore but there are still not all 600x800 Pixels visible.
I added a border this time to make sure that I see it correctly:

Are there any more requirements to the image in order for it to get displayed correctly?
Your example image is working fine btw.

Ah, nevermind, I made a mistake.
I used Pillow to convert the image to grayscale however the code found in a StackOverflow answer apparently did not work correctly.
After using pngcrush like you said, it's displayed correctly.
Thanks for the help! :)

In case anyone else wants to convert their image to grayscale in Python, this code works:

from PIL import Image, ImageOps
ImageOps.grayscale(Image.open('image.png')).save('grayscale.png')

Great! 👍
