Error saving and loading TIFF with exif with version>10.1 #8038
Description
Hi,
I manage a library for geoscientific data. We use PIL to generate and load TIFF images, storing the coordinates of our TIFF images in the EXIF data. However, since version 10.2, the methods we were using no longer function properly and cause bugs. We are temporarily fixing the PIL version to 10.1 to avoid these issues.
Here are the details of the issue we are encountering:
Pillow 10.3
Windows 10
Python 3.10
Steps to reproduce the error:
tag = {
256: (128,),
257: (128,),
258: (8, 8, 8),
259: (1,),
33922: (0.0, 0.0, 0.0, 522796.33210329525, 7244067.563364625, 0.0),
42113: ("255",),
262: (2,),
33550: (0.9990415797117552, 0.999041579711816, 0.0),
339: (1, 1, 1),
277: (3,),
278: (5,),
284: (1,),
34737: ("WGS 84 / UTM zone 34N|WGS 84|",),
}
# create and save a tiff
image = Image.fromarray(
np.random.randint(0, 255, (128, 128, 3)).astype("uint8"), "RGB"
)
for id_ in tag.items():
image.getexif()[id_[0]] = id_[1]
# image.save("testtif.tif", exif=image.getexif()) # was working with 10.1
image.save("testtif.tif", exif=image.getexif(), compression='tiff_deflate') # for 10.3
image = Image.open("testtif.tif") # was working with 10.1Is this behaviour a bug or an intended change in the API? Are there some specific options or settings that could serve as a workaround?
Thank you!

Not related to your issue, but fyi there's an
ExifTagsmodule you can use. https://github.com/python-pillow/Pillow/blob/main/src/PIL/ExifTags.pyso instead of
you can do

The error you're experiencing is
NotImplementedError: multistrip support not yet implemented, yes?This has started happening for you because of #7654. It allowed the user to set the ROWSPERSTRIP tag, number 278. You're providing (5,) for that tag. The error is being triggered because 5 is smaller than 128, the height of your image, and as the error says, we have not yet implemented multistrip support.
The simplest solution would be to just remove 278 from your
tagdictionary.[-]Error save an load tiff image with exif with version>10.1[/-][+]Error saving and loading TIFF with exif with version>10.1[/+]MatthieuCMira commentedon May 1, 2024
Yes, you're right it worked.
It solves my problem if I don't use
compression="tiff_deflate.Thank you very much!
