Trying to port up from *old* django this class/function and having a bit of
trouble with the im.save which returns
Exception Type: IOError Exception Value:
[Errno 2] No such file or directory
where the no file or directroy string is a correct path from MEDIA ROOT
concatenated with tiny/filename.jpg
code extract
def makeTinyThumbnail(self):
sphot = str(self.photo)
tinythumb = sphot.replace('\\','/').split('/')
tinythumb[-1] = 'tiny/'+tinythumb[-1]
tinythumb = '/'.join(tinythumb)
if not os.path.exists(MEDIA_ROOT+tinythumb):
im = Image.open(self.photo)
src_width, src_height = im.size
src_ratio = float(src_width) / float(src_height)
dst_width, dst_height = 100, 100
dst_ratio = float(dst_width) / float(dst_height)
if dst_ratio < src_ratio:
crop_height = src_height
crop_width = crop_height * dst_ratio
x_offset = float(src_width - crop_width) / 2
y_offset = 0
else:
crop_width = src_width
crop_height = crop_width / dst_ratio
x_offset = 0

im = im.crop((int(x_offset), int(y_offset),
int(x_offset)+int(crop_width), int(y_offset)+int(crop_height)))
im.thumbnail(TINY_SIZE,Image.ANTIALIAS)
im.save(MEDIA_ROOT+tinythumb, 'JPEG')
class Picture(models.Model):
