|
# a utility to identify image files
|
|
#
|
|
# this script identifies image files, extracting size and
|
|
# pixel mode information for known file formats. Note that
|
|
# you don't need the PIL C extension to use this module.

# History:
|
|
# 0.0 1995-09-01 fl Created
|
|
# 0.1 1996-05-18 fl Modified options, added debugging mode
|
|
# 0.2 1996-12-29 fl Added verify mode
|
|
# 0.3 1999-06-05 fl Don't mess up on class exceptions (1.5.2 and later)
|
|
# 0.4 2003-09-30 fl Expand wildcards on Windows; robustness tweaks
