Thanks for reporting the issue. I don't have a machine running Ventura currently, but if you can set that variable, I'd love to see what it says:

CG_PDF_VERBOSE=1 scanline -v

Hi Scott,

here is the output you are asking for (with export CG_PDF_VERBOSE=1):

Hi Ralph,

I do see that message on Ventura Betas as well, though it doesn't appear to actually cause any issues. Are you experiencing any problems as a result? I did try to find a way around it, but it appears that the scanner is creating a JPEG without orientation information and PDFPage doesn't like that. Changing the underlying format to TIFF makes the message go away, but increases the file size. There may be a way to provide the metadata that PDFPage is expecting, but I don't see any documentation on what that is. Some trial-and-error came up empty.

For now, if it's not causing any problems, let's wait and see if it's still an issue in the Ventura RC.
