Comment: 1
There are many optional "parameters" defined in the [pdf] reference for
various profiles
or filters (both required and optional for PDF/is) that we have not either
made their support
discoverable by the creator or specified thier support requirements.
Example: The Gamma, BlackPoint and Matrix(for CalRGB) entries in the
colorspace dictionary(s)
are optional in CalGray/CalRGB.
Comment/Question 2.
Section 3.3.1.1.4 of PDF/is describes "Memory"....
In MBytes ???
Can we assume this is at least no more than what the renderer returns in
the pdfis-cache-size-k-octets-supported ?
Rounded down??
The section mentions this being in addition to the 2Mbyte base memory but I
don't see
any other mention of base memory. (Should we assume this is a renderer
requirement???) What's is
this assumed to be used for???
Comment/Question 3.
Section 3.3.11.3 of PDF/is describes "Banding"
The section mentions that a document being created for an unknown renderer
should not use banding.
Considering that for interoperability purposes, a creator would probably
create a "least common denominator"
file that avoided optional parts of PDF/is if possible and used the lowest
resolution etc.....
Is recommending/requiring that the creator assume a 2Mbyte cache in the
renderer and banding if necessary such a huge problem???
