2009.01.05 15:59 "[Tiff] TIFF standards and technical notes", by Sheila M. Morrissey

Hello,

I have been reviewing the TIFF specifications on the Adobe site, and the documentation at www.reomotesensing.org <http://www.reomotesensing.org/>, and had a question -

There is a technical note on the remotesensing.org site on the Tiff 6.0 spec at http://www.remotesensing.org/libtiff/TIFFTechNote2.html (dated 17-mar-95) discussing Sections 21 and 22 in the TIFF manual --

Section 22 material is NOT updated in the 6.0 version of the spec on the Adobe site (http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf, last revisions seem to be in Sept 1995), but the material all appears in the Photoshop Tiff Technical Notes (http://partners.adobe.com/public/developer/en/tiff/TIFFphotoshop.pdf).

It didn't look to me like the elaboration of YCbCr images (suggested to be added to section 21) ever made it in to any of the 3 documents on the Adobe site - do you know anything about this? Does the libtiff codebase reflect the changes in the technical note? Can you speak to the status of this correction as a matter of usage in the creating and processing of TIFF files?

Thank you.

Sheila Morrissey
