Django-Using PIL with Django

原文链接：
Here’s a simple django view which creates a PIL image on the fly, and returns it as a PNG image:

from django.utils.httpwrappers import HttpResponse from PIL import Image import random
INK = "red", "blue", "green", "yellow" def image(request): # ... create/load image here ... image = Image.new("RGB", (800, 600), random.choice(INK)) # serialize to HTTP response response = HttpResponse(mimetype="image/png")
    image.save(response, "PNG") return response

To draw things on the fly, you can use either PIL’s ImageDraw module, or the  module:

from django.utils.httpwrappers import HttpResponse from PIL import Image from aggdraw import Draw, Pen, Brush, Font import random def graphics(request):

    image = Image.new("RGB", (800, 600), "white")
    draw = Draw(image) # ... draw graphics here ... for i in range(20):
        x0 = random.randint(0, image.size[0])
        y0 = random.randint(0, image.size[1])
        x1 = random.randint(0, image.size[0])
        y1 = random.randint(0, image.size[1])
        draw.rectangle((x0, y0, x1, y1), Pen(random.choice(INK), 5))

    draw.flush()

    response = HttpResponse(mimetype="image/png")
    image.save(response, "PNG") return response
