Scope of PDF Name Objects

Section 3.2.4 (page 56) of the Adobe PDF Reference sixth edition (for PDF version 1.7), states:
"A name object is an atomic symbol uniquely defined by a sequence of characters. Uniquely defined means that any two name objects made up of the same sequence of characters are identically the same object."
I initially took this to mean that names are unique across a document, but recently have found that this is not the case (I tried to cache fonts this way, but discovered names are re-used for different fonts on different pages in certain documents -- the aforementioned PDF Reference document being one of them!)
So my question is: what scope does the uniqueness of PDF Name Objects have? Are they guaranteed unique per-page? It this specified anywhere?
Thanks,
H

Don't confuse the name object with the VALUE associated with a name in a dictionary.
/Type is a name, as is /F1 and /Foo, etc..
However, when you have them in a dictionary, such as
<< /Resources << /F1 1 0 R >> >>
Then /Resources and /F1 are still names - and will always be names.  BUT what object #1 is going to be something else (most likely a dictionary in this case).

  • Does acrobat has any option to read pdf content objects(stamps, layers, images etc) without using pl

    Does acrobat has any option to read pdf content objects(stamps, layers, images etc) without using plug-in in c#.net ?
    My requirement is read a pdf file and extract all the page objects(stampls, layers and images) along with its coordinates. Is it possible to get without using plug-ins in c#.net ?
    Please hlep me.

    These are very different things.
    JavaScript has some access to layers (called OCG). Layers are just names and have no coordinates to retrieve.
    Stamps may be annotations; there is some minimal access to these too I think. It may be hard to identify what is, and is not, a stamp even with a plug-in.
    Images are part of the actual page contents, and are only accessible to plug-ins.

  • How to Edit/Save PDF without Object Stream Compression?

    Hi,
    Whenever I am removing/replacing a page in the PDF file, "Object Stream Compression" applied automatically. But in the original PDF there is no "Object Stream Compression" initially.
    I can remove this "Object Stream Compression" using the option "PDF OPTIMIZER->Cleanup->Remove->Compression" manually, but I want to remove/replace a page in the PDF file without "Page Has Object Stream Compression".
    Preflight Report for the Original PDF
    Preflight Report for the Edited PDF (One Page Removed)
    Could you advise anyone, how to solve the above mentioned issue?
    I hope your favorable response from the Acrobat experts.
    Regards,
    TSR

    Thanks for the reply.
    I just want to remind you that I don't use any other workflow to retain/remove the "object stream compression".
    My question is "object stream compression" was not present in the original PDF  but after removing a page (Ex: Back cover) "object stream compression" applied automatically. Why?
    Note: I am using "Acrobat X pro" to remove a page (Ex: Back cover) from the original PDF and not using any other PDF tools for the above.
    Now i hope that you will understand the actual issue.

  • PDF name didn't match the file-attributes

    Hello Community,
    I imported some PDF-Files via iTunes (Win7) on my Ipad. I also edited the file information and the pdf-name (in iTunes & win7) as required. The synchronisation worked perfect, after opening the pdf-file in iBooks the name changed. Is there any chance to change this name in the list-view in iBooks? From which position come the iBooks name? I can say that it isn't the file-properties (win7) or the iTunes-Information.
    Thank you for the help.
    Daniel

    Thanks Laura,
    This incident happened only once. I re-made another PDF using the same method and it was fine. I tried many time but I can't replicate the error/problem. The areas where was dropped out in the PDF is a solid color oval with 80% transparency, the other area is a gradient color with 100% transparency. There are similar areas like those in the document but strange enough they are not affected....
    The PDF is exactly as expected on the Overprint Preview (using the very same outlined AI file, there is NO spot colors).

  • HttpSession.setAttribute( name,object ) object- vector

    In HttpSession we have void setAttribute(name,object)
    and object getAttribute(name
    In this can i set the vector as an object in
    setAttribute(name,object) and retreive the vector by
    casting in the getAttribute(name) ?
    The code ....
    Vector v = new Vector();
    // adding elements in vector
    session.setAttribute(name,vector);
    Vector recV = (Vector)session.getAttribute(name);
    is it possible ?
    Thank you

    Yes. Session.setAttribute(), ServletContext.setAttribute(), etc. are all dictionary lookups.

  • Controlling PDF Name

    I've seen this discussed elsewhere, but for earlier versions, so I hope there's an answer now!
    I've got CS3, and when I go to create a PDF (via Adobe PDF Presets) the default name is (I assume) from some earlier incarnation of the file. I want filename.pdf, and have to click on the indd file and change the suffix.
    I can't find any preference relating to this. Is there some way of controlling it? These are legacy documents we're processing for another company, so I don't know the history.
    TIA

    I know in CS2, Adobe had no controls to reset the PDF name to default to the document title. The only way to control it was to export as .inx and reimport, which reset the PDF default (as the PDF default name is not part of the .inx file).
    I am uncertain whether they finally put controls in for this in CS3 or CS4. If CS4, then you'll have to follow the same procedure as for CS2 or live with it.

  • When saving a pdf the objects on the page appear offset of the page boundries.

    This happens mostly in illustrator but it just happened again to me while printing a .ps booklet out of indesign and converting to a pdf using distiller.
    See the image below:
    The left shows my InDesign Document. On the right is the pdf that results from the save. As you can see the page boundaries are being completely disregarded when saving the pdf and everything is equally shifted down and to the right.
    Here is an example of me having the same problem in illustrator:
    As you can see there is sometimes zero correlation between what is on the artboard and what page the objects end up on in the pdf.
    This problem also has another strange symptom, it seems to have to do with dragging images from firefox onto an artboard in illustrator. The image is place automatically in the center and all objects in the file move together in one direction. see before and after photos below:
    Before:
    After image dragged in:
    You can even continue to drag images in and it will move in the same direction the same amount every time:
    I'm running Adobe CS6 on OSX 10.9.1.
    Thanks in advance!

    In so many words: We can't know. You have not provided any details about your exact settings, what version of Acrobat, your placed images, color settings, color profiles and a million other things including perhaps providing your test fioles for inspection by other people.

  • XPATH - Scope of BPM container objects

    Hi,
    I have a question.
    When we declare container objects in BPM, the scope is mentioned as "Process".
    Does this mean that I can use any container objects declared within the process anywhere.
    What I am trying to do is, after a SYNC step, I have a ASYNC step. I have to use the response from the SYNC step in the ASYNC step.
    The problem is that the interface of SYNC's response differs from ASYNC's request.
    So I was wondering if I could mention the XPATH of SYNC's response while doing the receiver determination for ASYNC.
    I tried and it does not work. But technically I assume it has to work.
    Could someone point out where I am going wrong ( My understanding / Steps that I am following ).
    Thank you team.

    When you do the mapping outside of BPM (which is recommended anyway)
    then you send the sync response directly as async request and do receiver det. and mapping. to the new structure.
    when you do mapping and receiver det. inside BPM, you should be able to access all container elements, but I do not have experience with this.

  • Bounding box of placed pdf 'reflecting' objects of parent Ai file... Not what I want!

    As a self-taught Illustrator CS3 user I keep running into confounding issues.  The latest is this:
    Artboard is US letter size.  I have a placed jpg image in the top half that extends beyond the artboard on one side.  Only want 3/4 of the jpg content
    in the final product.
    Some text at the bottom.
    All in all a basic poster. 
    A clipping mask hides the part of the image that extends past the arboard.
    I save this 'parent' Ai file as a copy PDF - no layers - no editing - no thumbnails ect.  Keep original Ai parent file for later editing.
    I want to put this PDF into another ai document, but when I do, the bounding box extends past the pdf content out to
    where the jpg image is in the parent Ai file.
    Why?  Why can't I save a pdf that produces a stand alone img/doc without any apparent connection to its 'parent'?  Why can't this just happen without me having to crop the original jpg in photoshop to fit the parent Ai document perfectly and or somehow crop the image in the parent Ai. 
    Oh, and I have tried the crop tool and "make" crop area under the Object menu that contains only what is showing on the artboard.
    Same result.
    PDF that in Preview shows correctly but when placed in another ai file somehow 'becomes' larger with a bounding box that includes much more than what is actually there.
    This is maddeningly stupid IMO.
    Hope someone can be that patient professor of the design/Illustrator course that I can't afford, but that I need so desperately all the time.

    Why?
    I don't know; I just chalk it up as another instance of the sloppiness that permeates Illustrator, and the convoluted multiple nested clipping paths so common in PDFs.
    If I place the PDF as a Link, its bounding box corresponds to the clipping mask of the PDF.
    If I place the PDF embedded, not linked, then I get the result you describe.
    That arguably sort of makes sense in that, when you "place" (but embed) a PDF in Illustrator, you're really importing its content, including the nested clipping paths; and AI CS3 and prior always displays the bounds and edges of masked portions of clipping paths. When you "place" the PDF as a link, it's a preview that displays on the page, as if you were just linking a raster image.
    In CS4 and CS5, Adobe finally fixed the silliness of displaying edges of masked portions of the content of clipping paths, so in those versions, it probably acts the way you want whether linked or embedded. (I only have CS3 on this laptop, so can't verify right now.)

  • Problem embedding pdf as object in Word 2010 64-bit

    Using MS Word 2010 64-bit & Acrobat X Pro on Win 7 Ult. Getting following error when trying to embed a pdf file as an object in a doc(x) file:

    Hi Dave,
    Maurice's thread was locked because he is using Office 2010 Beta, and his post is in the forum for Office Beta, since the Beta is past due, the whole forum is locked.
    Let's go back to your question.
    Have you installed the Office 2010 Service Pack 1? The service pack fixes many issues, you should try if you haven't.
    Download
    the Microsoft Office 2010 Service Pack 1 64-bit package now.
    I may to metion is that all I know the Office 2010 64-bit will work smoothly with Windows 7 64-bit, cause I'm using it for my daily work.
    So, the problem you met with mostly caused by the 3rd-party add-ins/services.
    Have you tried to open the document by holding the Ctrl key? This will open the document in safe mode, if you are able to do so, this will help us to narrow down the root cause.
    If it will crash even when you start it in safe mode, let's try to run a clean boot to check this issue. In a clean boot, lots of service will be disabled, if we wouldn't get problem in a clean boot, then we can enable the service little by little, then
    we can find out which service might cause this issue.
    For a detail instruction, you can refer to this kb:
    http://support.microsoft.com/kb/929135
    Let me know the result, any questions, feel free to let me know.
    Sincerely,
