I'm trying to get Kivy to load image which was saved in memory by PIL after editing. I'm using answers from this question as method: Load image from memory in Kivy.
However, it does not work. This is my code:
from PIL import Image as PIL_Image
from kivy.app import App
from kivy.core.image import Image as CoreImage
from kivy.uix.image import Image
import io
class MyApp(App):
def build(self):
image_from_memory = CoreImage(memory_saved_image, ext='png')
image_to_show = Image(source='')
image_to_show.texture = image_from_memory.texture
return image_to_show
if __name__ == "__main__":
memory_saved_image = io.BytesIO()
pil_edited_image = PIL_Image.open('test.png')
# some non-related PIL image editing in here
pil_edited_image.save(memory_saved_image, 'png')
MyApp().run()
And this is my error message, including related log-message:
[WARNING] [Image ] Unable to load image <<_io.BytesIO object at 0x000000000372F108>>
Traceback (most recent call last):

Exception: SDL2: Unable to load image
When I try to open this image from memory using PIL, it works, so the memory is not corrupt.
