Modifying an existing PDF file is several magnitues more complicated than creating one from scratch. The PDF standard is VERY complicated and contains a myriad of features with their specific syntax elements. In order to modify an existing PDF you have to be able to understand every syntax element that occures in the PDF, or you may end up corrupting the file.
When you create a new PDF you can pick out the syntax elements that your tool supports and forget about the 95 other procent.
There are many PDF Toolkits than can create PDF files, a few that can open PDF files and present them, and almost none that can edit them. The Adobe PDF Editor being one of the few that can do that, but nobody is going to give away such a Toolkit for free.

    Hi Lynn ,
    Basically i want to read the mentor graphics drawing file data in a labview front panel, so that i can display the components as we see in the mentor graphics development enviornement and should be able to click on the components to perform the tests associated with the same.For this,i think i need to have the BOM kind of data only as i need the components data associated with the drawing file,after this i would create a custom control for each and every component and then call the tests associated with it as soon as the user clicks on the same.I hope you understand my requirements.

  • Merge data and a PDF file?

    Hi,
    I´m trying to render/merge data into a PDF file using FormServer (7.0) and .NET. I notice that if I use the xdp version of the pdf, FormServer will return a pdf with the merged data. However, I cannot acomplish this if instead of a xdp file document I use a pdf file (dynamic 7.0 created with livecycle designer 8).
    This works:
    String sFormPreference = "PDFForm";
    String sFormQuery = "ExpenseClaim.xdp";
    This doesn´t woks:
    String sFormPreference = "PDFForm";
    String sFormQuery = "ExpenseClaim.pdf";
    Isn´t it possible to merge data directly into a PDF using FormServer. I rather use a pdf file instead of a xdp file, because, a xdp file will need to be converted to a PDF file. Thus it will spent more time accomplishing the merge.
    Thank you

    Try using PDFMerge as the transformation.

  • Delete data from a flat file using PL/SQL -- Please help.. urgent

    Hi All,
    We are writing data to a flat file using Text_IO.Put_Line command. We want to delete data / record from that file after data is written onto it.
    Please let us know if this is possible.
    Thanks in advance.
    Vaishali

    There's nothing in UTL_FILE to do this, so your options are either to write a Java stored procedure to do it or to use whatever mechanism the host operating system supports for editing files.
    Alternatively, you could write a PL/SQL procedure to read each line in from the file and then write them out to a second file, discarding the line you don't want along the way.

  • Need guidance entering my own data in a PDF file

    Please refer to this example:
    http://www.gnupdf.org/Introduction_to_PDF
    I am trying to teach myself PDF internals. My immediate objective is to save some private data in my PDF files. My data is structured as "variable/value" pairs but I chose not to save it as custom properties because of its bulk and the possibility of confusion and undesired manipulation by the end user.
    The above example immediately suggests that I should use an object of "dictionary" type. Let's try to assemble the file manually:
    44 0 obj
    <<
      (Favorite Baseball Team) (Boston Red Sox)
      (Age) (35)
      (Planet of Birth) (Klingon)
    >>
    endobj
    Is the above initial attempt correct? I will of course use the corresponding API to create the dictionary, but I am concerned about breaking things. Won't Acrobat get confused when it finds this foreign stuff?
    TIA,
    -Ramon

    Hi Leonard,
    Thanks for your always valuable help. FYI, my data is of a global nature. I suppose I should come up with some unique name ("MyPrivateData" or something) and place such entry in the Catalog?
    This thread brings up a related topic. It is about the uniqueness of the JavaScript namespace. My PDF files are generated automatically and JavaScript code is added to them. I haven't done any tests yet, but I foresee the following problem: those generated PDF files may end up being merged with each other which brings the potential of namespace conflicts.
    Let's say that the first JS-laden document has 3 pages and another one has 2 pages. I suppose there is no way to restrict it like: "this JS code applies to the first 3 pages only". As soon as the 2 documents are merged all the JS code (and worst of all: the variable and function names) applies to the 5 combined pages, correct?
    There are 2 possible solutions:
    - Perhaps there is a way to declare some JS code as belonging to one page only?
    - Use collections. This brings a whole new layer of complexity and expense.
    Thanks again,
    -Ramon

    It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.
    [http://java.sun.com/docs/books/tutorial/essential/io/]
    *Unless you write a bunch of JNI code to replicate what the java.io classes are doing.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

  • I have written a binary file with a specific header format in LABVIEW 8.6 and tried to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?

    I have written a binary file with a specific header format in LABVIEW 8.6 and tried  to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?

    I can think of two possible stumbling blocks:
    What are your 8.6 options for "byte order" and "prepend array or string size"?
    Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

    I know if we use UTL_FILE.get_line we can read the whole line...but i need to read the tab separated value separately.....If it's a text file then UTL_FILE will only allow you to read it a line at a time. It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
    If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

  • Can I use Visual Basic to covert form user data from multiple .pdf files to a single .csv file?

    Can I use Visual Basic to covert form user data from multiple .pdf files to a single .csv file?  If so, how?

    You can automate Acrobat using IAC (InterApplication Communications), as documented in the Acrobat SDK. Your program could loop through a collection of PDFs, load them in Acrobat, extract the form data from each, and generate a CSV file that contains the data.
    Acrobat can also do this with its "Merge Data Files into Spreadsheet" function, but this is a manual process.

  • Is it possible to extract the contents of any PDF file using Adobe PDF SDK?

    Is it possible to extract the contents of any PDF file using Adobe PDF SDK?
    For Example: There is one pdf file. Let us say xxx.pdf with 32 pages. I am interested in only in a topic present at 10th page. Can I extract this information and save it into another pdf file (means new pdf file)?

    Thanks Irosenth,
    I am actually interested in extract the page and create a new PDF with that page. But still there is a catch that on which basis the page needs to extract either on PAGE number OR on Bookmark basis.
    But here in this scenario assume I am looking for the PDF file, now I want to save only page 5. How can I extract page 5 automatically/programmatuically? Or in simple word how can I get the reference link of page 5?
    Here I am not getting clear picture that Do I need both SDK Adobe & Acrobat to achieve this requirement. And more over you have mentioned that SDK itself is free. But on Adobe side it is mentioned that it is available by license only with this I have another doubt: To work my desktop/system application with Adobe PDF library, this library needs to distribute with the application. So in this case will it be chargeable for each and every deployment.
    Could you please provide me the link from where I can download the SDK? So that I can do some excerise with SDK to figure out the exact flow of functionality to work with my application.
