Image
=====
Core classes for loading images and converting them to a
:class:`~kivy.graphics.texture.Texture`. The raw image data can be keep in
memory for further access.
.. versionchanged:: 1.11.0
Add support for argb and abgr image data
In-memory image loading
-----------------------
.. versionadded:: 1.9.0
Official support for in-memory loading. Not all the providers support it,
but currently SDL2, pygame, pil and imageio work.
To load an image with a filename, you would usually do::
from kivy.core.image import Image as CoreImage
im = CoreImage("image.png")
You can also load the image data directly from a memory block. Instead of
passing the filename, you'll need to pass the data as a BytesIO object
together with an "ext" parameter. Both are mandatory::
import io
from kivy.core.image import Image as CoreImage
data = io.BytesIO(open("image.png", "rb").read())
im = CoreImage(data, ext="png")
By default, the image will not be cached as our internal cache requires a
filename. If you want caching, add a filename that represents your file (it
will be used only for caching)::
import io
from kivy.core.image import Image as CoreImage
data = io.BytesIO(open("image.png", "rb").read())
im = CoreImage(data, ext="png", filename="image.png")
Saving an image
---------------
A CoreImage can be saved to a file::
from kivy.core.image import Image as CoreImage
image = CoreImage(...)
image.save("/tmp/test.png")
Or you can get the bytes (new in `1.11.0`):
import io
from kivy.core.image import Image as CoreImage
data = io.BytesIO()
image = CoreImage(...)
image.save(data, fmt="png")
png_bytes = data.read()

Delay in seconds between each animation frame. Lower values means
faster animation.
