Using PIL with Django

Using PIL with Django
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 aggdraw 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
