I've reimplemented the code I found somewhere on the web within my models file. The earlier version was incapable of converting all formats to JPG while this code converts all formats and compresses all of them successfully.
You need to have PILLOW installed for this to work.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | from PIL import Image as Img
import StringIO
class Images(models.Model):
image = models.ImageField()
def save(self, *args, **kwargs):
if self.image:
img = Img.open(StringIO.StringIO(self.image.read()))
if img.mode != 'RGB':
img = img.convert('RGB')
img.thumbnail((self.image.width/1.5,self.image.height/1.5), Img.ANTIALIAS)
output = StringIO.StringIO()
img.save(output, format='JPEG', quality=70)
output.seek(0)
self.image= InMemoryUploadedFile(output,'ImageField', "%s.jpg" %self.image.name.split('.')[0], 'image/jpeg', output.len, None)
super(Images, self).save(*args, **kwargs)
