コードサンプル

from PIL import Image, ImageDraw

a = Image.open('img/seven.jpeg') #28 x 28
b = Image.open('img/cifar1.png') #32 x 32
b = b.resize((28, 28))
a_txt = 'seven'
b_txt = 'cifar10'

new = Image.new('RGB', (160, 100), (230, 230, 230))
new.paste(a, (20, 20))
new.paste(b, (20 + 28 + 50, 20))
draw = ImageDraw.Draw(new)
draw.text((20, 60), a_txt, fill='#000000')
draw.text((20 + 28 + 50, 60), b_txt, fill='#000000')
new.save('img/new.png')
