Image.show() defaults to PNG ignoring animated GIFs #6608
Description
When using show() for an animated GIF with version 9.2.0, Pillow converts the image to PNG by default thus eliminating the animation.
I suggest the following change in "ImageShow.py" to preserve the animation:
def save_image(self, image):
"""Save to temporary file and return filename."""
if image.format == 'GIF' and image.is_animated:
suffix = "." + image.format
f, filename = tempfile.mkstemp(suffix)
os.close(f)
image.save(filename, save_all=True)
return filename
else:
image_format = self.get_format(image)
return image._dump(format=image_format, **self.options)
