    "",
    bc.ColorRepresentation.srgb(),
    bc.ColorRepresentation.srgb(),
    bc.Dictionary.create().add("gamma", gamma),
)

ctx = bc.Context()
composition = graph.execute(ctx)
data_bytes = composition.to_image_bytes(ctx)
img = Image.open(io.BytesIO(data_bytes))
img.thumbnail((400, 400))  # Remove this line for full resolution
