Our poor friend Hermitian is still struggling with the undeniable fact that the WH LFBC contains an embedded JPEG encoded image files with a comment that shows YCbCr. As I and others have shown the same comment shows up in a Xerox Work Flow. However, Hermitian seems to be struggling with his tools and unable to verify these simple facts for himself.
Reality Check took pity on him and provided him with a link to a Preview encoded Xerox Multicenter PDF which, of course, shows a YCbCr comment tag.
Expect Hermitian to continue to refuse to accept these simple facts, leaving the Xerox Work Flow as an unassailed challenge to the Cold Case Posse, to the extent that the CCP appears to have decided to ignore the findings.
As an added bonus, the JPEG encoded file shows the same Quantization Matrix as the one found in the WH LFBC.
