class Image(models.Model):
      license_type = (
            ('Royalty-Free','Royalty-Free'),
            ('Rights-Managed','Rights-Managed')
          )
      image_number = models.CharField(default=random_image_number,max_length=12,unique=True)
      title = models.CharField(default=random_image_number,max_length = 100)
      image = models.ImageField(upload_to = 'image' , default = 'demo/demo.png')
      thumbnail = models.ImageField(upload_to='thumbs', blank=True, null=True)
      category = models.ForeignKey('Category', null=True, blank=True, on_delete=models.CASCADE)
      shoot = models.ForeignKey(ImageShoot, on_delete=models.CASCADE, related_name='Image', null=True,blank=True)
      image_keyword = models.CharField(max_length=500)
      description = models.TextField(max_length=3000,null=True,blank=True)
      credit = models.CharField(max_length=150, null=True,blank=True)
      location = models.CharField(max_length=100, null=True,blank=True)
      license_type = models.CharField(max_length=20,choices=license_type, default='')
      uploaded_at = models.TimeField(auto_now_add=True)

      def __str__(self):
          return self.title

      def save(self, *args, **kwargs):    
         super(Image, self).save(*args, **kwargs)

     def make_thumbnail(self):
         TXT_BOX = (1300, 1300)  # Depends on the font size you choose
         REPEAT_X = 3  # How close together horizontally
         REPEAT_Y = 4  # How close together vertically
         fh = storage.open(self.image.path)
         base = PILImage.open(fh).convert('RGBA')
         base.load()

         d = ImageDraw.Draw(txt)
         d.text((5, 5), "liveimages.in", font=fnt, fill=(255, 255, 255, 128))
         txt = txt.rotate(45, expand=True)  # use expand to make sure the box still fits

   # draw step_x * step_y boxes
   # if REPEAT_X and REPEAT_Y are 1 the boxes are too far apart
        step_x = int(base.size[0] / txt.size[0] * REPEAT_X)
        step_y = int(base.size[1] / txt.size[1] * REPEAT_Y)

        for x_ratio in range(0, step_x):

                y = int(height * y_ratio / step_y)
                base.alpha_composite(txt, dest=(x, y))  # in-place adding of txt
       base.thumbnail((1000, 1000), PILImage.ANTIALIAS)
       fh.close()

       thumb_name, thumb_extension = os.path.splitext(self.image.name)
       thumb_extension = thumb_extension.lower()

       thumb_filename = thumb_name + '_thumb' + thumb_extension
# Save the new image    
       i_out = base.convert('RGB')
       temp_thumb = BytesIO()        
       i_out.save(temp_thumb, 'JPEG')
       temp_thumb.seek(0)
       if not self.thumbnail:
    # Load a ContentFile into the thumbnail field so it gets saved
          self.thumbnail.save(thumb_filename, ContentFile(temp_thumb.read()), save=True)
          temp_thumb.close()
       return True
