<br><font size=2 face="sans-serif">Bill, that is a huge mouthful. </font>
<br>
<br><font size=2 face="sans-serif">Sounds to me like Finished-Page-Image-Cell
should have been named Imposed-Page-Image-Cell (Finished implies trimmed,
for example, which could affect where things appear to have ended up on
the sheet w.r.t. various margins). </font>
<br>
<br><font size=2 face="sans-serif">I understand why the MFD model wants
to describe basic capabilities and limitations of the device and its services
but, are we going too far by delving into concepts (such as content positioning)
which are most frequently controlled by the PDL?</font>

<br><font size=4 color=#004080 face="Calibri">OK, I delved further into
the Production Printing Attributes document. At least to a non Production
Printing person, these are arcane attributes but do correspond to elements
that we have in the model. </font>
<br><font size=4 color=#004080 face="Calibri"> </font>
<br><font size=4 color=#004080 face="Calibri">At first look I was interpreting
“Image” as Content Area. But positioning the image first must consider
the concepts of Finished-Page-Image Cell and Imposition. Since the
Finished-Page-Image Cell is defined as the region on the surface
of a sheet where the Finished-Page Image is placed, maybe this is the Content
Region? Reading further, “When imposition is not applied, the Finished-Page-Image
Cell coincides with the entire surface of one side of the sheet. When imposition
is applied, a) the sheet is partitioned into multiple non-overlapping Finished-Page-Image
Cells, typically in a rectangular grid, and b) the area near the edges
of the sheet may not belong to any Finished-Page-Image Cell.” So the Finished-Page-Image
Cell in one case is the entire sheet surface (and does not consider engine
margins) and in the other case is a grid used for addressing the placement
of the image. </font>
<br><font size=4 color=#004080 face="Calibri"> </font>
<br><font size=4 color=#004080 face="Calibri">So “Image” (or Finished-Page
Image) is what is positioned and may correspond to Content Region.
Except the “image” attributes appear to only position the image, with
the coordinate system for the Image Shifting attributes being relative
to the Finished-Page-Image Cell. That is, the dimensions of the image
are determined by the PDL (and, realistically, limited by the margins).
</font>
<br><font size=4 color=#004080 face="Calibri"> </font>
<br><font size=4 color=#004080 face="Calibri">Even the positioning (or
“shifting”) of the image is not a simple question of x and y offset.</font>
<br><font size=3 color=#004080 face="Calibri"> </font>
<br><font size=4 color=#004080 face="Calibri">“… the Printer first positions
the Finished-Page Image [I assume relative to the origin of an identified
Finished-Page-Image Cell ] using the values it obtains for the “x-image-position”
and “y-image-position” attributes. Then it shifts the Finished-Page Image
by the amount it obtains for the “x-image-shift” and “y-image-shift”
attributes. Finally, for a Finished-Page Image that would be placed on
the front side of a sheet in the Finished Document, it shifts the Finished-Page
Image by the amount it obtains for the “x-side1-image-shift” and “y-side1-image-shift”.
For a Finished-Page Image that would be placed on the back side of a sheet
in the Finished Document, it shifts the Finished-Page Image by the amount
it obtains for the “x-side2-image-shift” and “y-side2-image-shift”
attributes”</font>
<br><font size=4 color=#004080 face="Calibri"> </font>
<br><font size=4 color=#004080 face="Calibri">Bottom line, for the MFD
overall, the questions are:</font>
<br><font size=4 color=#004080 face="Calibri">1. Margins
are defined relative to the media edges, and the content region cannot
extend into the margin areas (if the content that would occur in those
areas is to be printed.) However, Margins are device (or subunit)
elements, not Service elements . Therefore, should these be discussed
under Scan and Marker Subunit Media Content Coordinates?</font>
<br><font size=4 color=#004080 face="Calibri">2. Do we want
to define the coordinate system for Services using “Mark” or “Print”?
The elements:</font>
<br><font size=1 color=#004080 face="Arial">a. ImpositionTemplate</font>
<br><font size=1 color=#004080 face="Arial">b. XImagePosition</font>
<br><font size=1 color=#004080 face="Arial">c. XImageShift</font>
<br><font size=1 color=#004080 face="Arial">d. XSide1ImageShift</font>
<br><font size=1 color=#004080 face="Arial">e. XSide2ImageShift</font>
<br><font size=1 color=#004080 face="Arial">f. YImagePosition</font>
<br><font size=1 color=#004080 face="Arial">g. YImageShift</font>
<br><font size=1 color=#004080 face="Arial">h. YSide1ImageShift</font>
<br><font size=4 color=#004080 face="Calibri">are included in the model,
and perhaps we need to define them and the coordinate system which they
utilize. Certainly we need to distinguish the marking o</font><font size=4 face="Calibri">rigin
as the NW corner of the Media.</font>
<br><font size=4 face="Calibri"> </font>
<br><font size=4 face="Calibri">3. The MFD model has “Scan
Region” and “Copy Region” elements, but no Content Region. Are we going
to change that? The elements above are defined at the same level as Scan
Region, not as subelements of a Mark Region element (otherwise known as
the Finished-Page Image). Also, the Mark Region can be shifted, but
unlike Scan Regions, its size appears determined by the PDL, not the Job
Ticket. </font>
<br><font size=4 face="Calibri">4. Is the Copy (Service)
Region the same as the Scan Region?</font>
<br><font size=4 face="Calibri"> </font>
<br><font size=4 face="Calibri">Just a few questions. </font>
<br><font size=4 face="Calibri"> </font>
