  • Next message: McDonald, Ira: "RE: IFX> PDF/is Issue."

    Next meeting is Friday March 14 at 10am

    Summary:
    Media Sizes supported. Width: Intersection of A4 and letter. Clip box
    inch in from each side. If won't fit on renderer's page, can scale
    image (require isomorphic scaling) and must notify the receiving user.
    --- What about length? In the Feb 25 call we had pondered not bounding
    the length of a page an allowing the device to split the image across
    pages.
    Resolution: Require a min/max?
                    In the data - min and max in the data stream, not
    discrete values, but ranges or ok. 300 pdi min. 1200 max.
                    On the output device - 300 min. No maximum.
                    Image must be +- a point of the original size. (not per
    inch, per object)
    Required ColorSpace(s) - Require the device to support sRGB and gray
    gama 2.2; the sender can pick either of the two but MUST include the
    profile in the pdf/is data stream
     
    Only thing left to negotiate is buffer size....Just pick a size and then
    not negotiate. Put a stake at 4meg and turn during interop.. Remove
    memory size attribute

    Still open:
                Sender-URI Stamps.
          Coloring of attributes based on compression. (Resolutions)

    ToDo:
          Walk through references section and split into
    Normative-v-Informative

    Today's Conference Call Summary:
     
    Drop Flate from list of pdfis-compressions-supported (this used to be
    pdfis-profiles-supported)
    Make Masking mandatory for the receiver.
    Require both the sender and the receiver to support and use Banding.
    Drop support for Tiling.
    Color-space will be ICC with only the sRGP color profile. A pdfis
    device wouldn't have to process the profile, but the inclusion of the
    profile in the datastream would allow a PDF reader to process the
    document.
     
    Coloring by pdfis compression schemes:
                No longer need the following attributes:
                    pdfis-compressions-supported (all compressions are
    required)
                    pdfis-color-spaces-supported (only one colorspace)
                    pdfis-data-encryption-supported (encryption types do
    not very based on compression)
                    pdfis-cache-size-k-octets-supported (we will just pick a
    single required number)
                    pdfis-orientation-supported - all images will be in
    landscape.
                     
    Still Open:
                Media Sizes supported. Width: Intersection of A4 and letter.
    Clip box inch in from each side. If won't fit in renderer, can scale
    image (required isomorphic scaling) and must notifiy the receiving user.

                Resolution: Require a min/max?
                    In the data - min and max in the data stream, not

          Required ColorSpace(s) - sRGB and gray gama 2.2
     
    Only thing left to negotiate is buffer size....Just pick a size and then
    not negotiate 4meg. No memory size attribute
