Agg BufferΒΆ

Use backend agg to access the figure canvas as an RGBA buffer, convert it to an array, and pass it to Pillow for rendering.

agg buffer
import numpy as np
from PIL import Image

from matplotlib.backends.backend_agg import FigureCanvasAgg
import matplotlib.pyplot as plt

plt.plot([1, 2, 3])

canvas = plt.gcf().canvas

agg = canvas.switch_backends(FigureCanvasAgg)
agg.draw()
X = np.asarray(agg.buffer_rgba())

# Pass off to PIL.
im = Image.fromarray(X)

# Uncomment this line to display the image using ImageMagick's `display` tool.
# im.show()
