Description
Attached is an example file with XMP data.
Exiftool shows the XMP data correctly:
# exiftool -v test.jpg
[...]
JPEG APP1 (1132 bytes):
+ [XMP directory, 1103 bytes]
| XMPToolkit = RICOH THETA SC Ver1.01
| ProjectionType = equirectangular
| UsePanoramaViewer = True
| CroppedAreaImageWidthPixels = 5376
| CroppedAreaImageHeightPixels = 2688
| FullPanoWidthPixels = 5376
| FullPanoHeightPixels = 2688
| CroppedAreaLeftPixels = 0
| CroppedAreaTopPixels = 0
| PosePitchDegrees = 2.8
| PoseRollDegrees = -1.3
[...]But when opening it with Pillow (defusedxml is installed), it returns no XMP Data:
>>> from PIL import Image
>>> img = Image.open("test.jpg")
>>> img.getxmp()
{}
>>> What did you expect to happen?
It should return the XMP data of the file.
What actually happened?
It returned an empty dict.
Digging into the code, I believe the problem is that the "APP1" segment seems to be padded with several b"\x00" so the getxmp() function doesn't find the marker due to rsplit being used. But there might be other issues:
>>> img = Image.open("test.jpg")
>>> for segment, content in img.applist:
... if segment == "APP1" and b"ns.adobe.com" in content:
... print(content)
...
