Photoshop PSD errors with Truncated File Read #7482
Description
What did you do?
Tried to open a Photoshop psd file that loads fine in Photoshop.
This issue came up as I'm processing multiple Photoshop psd files at a time on a project. Some files work fine, others do not. All of the files open fine in Photoshop 2023.
Ultimately for this purpose I'm just looking to get the dimensions of the file and confirm the format. But in the future would like to actually be doing more processing on these files.
What did you expect to happen?
I expected the file to be opened.
What actually happened?
The code errors with OSError: Truncated File Read despite using the ImageFile.LOAD_TRUNCATED_IMAGES = True option.
This same result happens whether opening from a file path or loading bytes and opening from there. I tried several methods recommended in previous Github issue submissions.
