Image drawing

pyProcessing - built upon OpenGL and Pyglet, which provide the actual graphics rendering. Since these are multiplatform, so ispyprocessing.

Django Imagekit processing the original image

from django.db import models
from imagekit.models import ImageSpec
from imagekit.processors import resize, Adjust

class Photo(models.Model):
    original_image = models.ImageField(upload_to='photos')
    thumbnail = ImageSpec([resize.Fit(50, 50)], image_field='original_image',
            format='JPEG', options={'quality': 90})
