A four-component JPEG whose EXIF orientation turns or flips it went
through the image decoder, which reads CMYK JPEGs as RGB, and was
stored as an RGB PNG without its inks. It is now stored the way a
turned CMYK TIFF is: its inks, 8 bits each, turned and written as a
CMYK TIFF with the turned resolution.
- vectorcraft_doc::cmyk::turned_cmyk turns the inks of a CMYK JPEG or
TIFF, next to stored_cmyk_tiff; tiff_inks is private again.
- raster_image swaps the resolution axes inline, as its HEIF branch
does.
- The links comment and the docs/target-app-parity.md line on EXIF
orientation now describe the turned CMYK TIFF.
