#20810 closed Bug (wontfix)

IOError raised when using EPS file in ImageField

Description

When using EPS file in ImageField, I get IOError("decoder eps not availabe") traceback. However, there is support for EPS files in Python:

from PIL import Image
Image.open('mathematica.eps')

<PIL.EpsImagePlugin.EpsImageFile image mode=RGB size=288x177 at 0x1B01320>

Problem occurs when Django tries to determine the resolution of image. It uses low level API which allows to determine size after loading just couple of chunks. The way EPS support is implemented, API does not triggered it. Attached patch provides a fallback option to use standard Image API.

  • Needs documentation unset
  • Needs tests unset
  • Patch needs improvement unset

PIL has been deprecated in Django 1.6 in favor of Pillow. Could you check if this is an issue there?

@timo, could you just explain your "wontfix"? Did someone establish that this was not a problem with Pillow?

"Won't fix" the issue with PIL & "needs info" as to whether or not it's a problem with Pillow.
