Can't open a tiff with old-style jpeg compressed file #7414
Labels
Comments
Can you attach a copy of the image itself? |
I upload it. |
Test code. import sys
from PIL import Image, TiffImagePlugin, features
filename = sys.argv[1]
TiffImagePlugin.DEBUG = True
TiffImagePlugin.READ_LIBTIFF = True
with Image.open(filename, mode='r', formats=['TIFF']) as img:
img.load()
TiffImagePlugin.READ_LIBTIFF = False
print(img.width, img.height)
print(img.info)
print(features.version_codec("libtiff")) |
I've created PR #7415 to resolve this. In the meantime, here's a version of your code with a line added to make it work. import sys
from PIL import Image, TiffImagePlugin, features
filename = sys.argv[1]
TiffImagePlugin.DEBUG = True
TiffImagePlugin.READ_LIBTIFF = True
# New line
TiffImagePlugin.OPEN_INFO[(b"II", 6, (1,), 1, (8,), ())] = ("L", "L")
with Image.open(filename, mode='r', formats=['TIFF']) as img:
img.load()
TiffImagePlugin.READ_LIBTIFF = False
print(img.width, img.height)
print(img.info)
print(features.version_codec("libtiff")) |
Thanks a lot。 |

What did you do?
I can get the infomation from tiffinfo.
But when i use python, get the under error.
PIL.UnidentifiedImageError: cannot identify image file '20230822143148.tif'
What did you expect to happen?
Pillow will open the file without error.
What actually happened?
I get the under error.
PIL.UnidentifiedImageError: cannot identify image file '20230822143148.tif'
