IP Review:
Review of Adobe's new PDF/is License agreement. Change from "IPPFax" to
"PDF/is", clarified "PWG" means and applies to candidate standard as
well as full standard.
Need HP permission to publish ICC grayscale profile. (Gray gama 2.2 =
sRBG with only one channel). Full PDF requires these to be imbedded,
however, a PDF/is only renderer could ignore the profiles because they
are the only ones allowed and therefore already known.
Other issues:
PDF/a - Trying to align with the requirements for PDF/a and make changes
when able. (Federal archiving standard) Major differences: interpolate
images(we require, they prohibit), no digital signatures.
Transparent text: already added. Text is not rendered but can used be
used for searching or for cut&paste. Optional for both consumer and
producer. Consumer can ignore them.
What should a consumer do if a MUST in PDF/is is not followed. Warn the
consumering user, attempt to find the next page and continue. In IPPFax
ippget notifications, can we send an indication that the page didn't
render properly?
PDF/is Walkthrough
DCT=JPEG - wherever there is a reference to DCT add (JPEG) so that Ira
can remember what DCT means.
Changes for PDF/a
Page tree must be balanced: no one node can have more than 12 children.
Crop box is the same as media box. (Add a note to this effect)
Content operators - Explain what they mean (DP and CM)
IPPFax:
Standard incryption is prohibited in IPPFax. (optional in PDF/is --
Should PDF/is also prohibit?).
Receiver MUST only support application/PDF in document-format-supported
and document-format.
IPPFax will reference document-format-version-supported and
document-format-version from the document-object specification and will
allow any PDF type versions and REQUIRE PDF/is v1.0.
Remove all references (including columns) to "coloring".
Digital-signature-supported and digital-signature will be moved the
document-object specification and IPPFax will reference that spec.
All administrative operations, including the set-ops and
enable-printer/disable-printer will be allowed but only if TLS has
authenticated the user and the user has rights to perform them.
