What does this TJ data mean?

Hello,
I am implementing a PDF parser in Objective-C  (using CoreGraphics API's) that will aid in PDF search. I know that the Tj and TJ operators are used for displaying text, and that to retrieve the text information from a page I should be looking there.
The problem comes in when there are weird operands in the TJ operator. Below is one such example:
[<1C>]TJ
0.7039 0 Td
[<1D>]TJ
What does the above highlighted red text data mean, in terms of the semantic information that it contains? During parsing, the output of the above 2 operands are the characters ˝ and ˛ respectively. Am I going to have to use the font encoding provided in the Resources dictionary of the page to decipher what these characters semantically mean?
Thanks a lot,
Michael

I assume you have a copy of ISO 32000-1:2008 available, so that you are reading what is written there first before asking.
The answer is that NOT ONLY do you need to read the font encoding information for ANY TEXT EXTRACTION, but you ALSO need to read the information from any embedded fonts for the embedded encoding information.  This is especially true for TrueType fonts vs. Type 1 fonts, and CID-based fonts.
And don't forget ToUnicode tables!
There is a section in ISO 32000-1 that describes the entire process of text extraction.

  • What does this Bridge message mean?

    I have a new Mac (and Photoshop Elements 11) and when I open Bridge I get this message:
    OLSException in OLS Adapter Startup
    /OLS/development/main/bridge/3.2.0/build/mac/../../sdk/src/COLS.cpp#19 : 16
    Should I be worried?
    (I've tried using PSE Organizer and I hate it. I'd rather stick with Bridge unless I'm headed for trouble.)
    What does this Bridge message mean?

    Bridge came with an earlier version of PSE, PSE6 I think. The Organizer comes with PSE 9 and PSE11. Like some other PSE users, I much prefer Bridge to the Organizer. I had no trouble using Bridge with PSE9 and an older Mac. But with PSE11 and my new Mac, I started getting this message. I wonder if anyone knows what this message means, if it portends trouble for me, if there is anything I should do to correct it?
    I posted this question on the Elements Forum and was told that it should be addressed on the Bridge Forum.

  • What does this error message mean and how do I solve it? "Sorry, one or more of the following command-line tools was not found:  /usr/bin/lsbom, /bin/pax, /bin/mkdir, /bin/chmod, or /usr/bin/update_prebinding."

    When I try to open up this program, Pacifist, I receive this error message. Here's a screenshot. http://i.imgur.com/v717w.jpg What does this error message mean and how do I solve it?

    It sounds like some of the Unix Executable commands were removed (or the permissions to those were modified) out of the /usr/bin/ folder.  You can try opening disk utility and repairing permissions on Macintosh HD or you can reboot your computer and holding down option-r when it comes back up to reinstall Lion again.  This will not delete your personal information or applications you have installed but it would be best to back it up to Time Machine before you do.  The article on how to do this is here. (http://www.apple.com/macosx/recovery/)  I have had to do this before and it works like a charm.  It should fix your issue but grab a cup of coffee because its going to take about 35 - 40 minutes depending on how fast your computer is.

  • What does this error message mean: "Filename: Mips32.ari TFTP Error: 'File not found' in AP-105"?

    Question: What does this error message mean: "Filename: Mips32.ari TFTP Error: ‘File not found’ in AP-105"?
    Product and Software: This article applies to AP-105.
    The root cause of this error is that the AP cannot perform a code upgrade.
    Scenario 1
    Check the ArubaOS code.
    The minimum requirement to bring up an AP-105 is ArubaOS 3.3.3+ or ArubaOS 3.4.1+.
    If the controller is running pre 3.3.3 code, upgrade the code to fix the issue.
    Scenario 2
    If the AP is not connected to the controller directly, bring up the AP in the controller and then connect it to the desired location. This process loads mips32.ari to the AP so that the AP can upgrade the code.
    Scenario 3
    The AP has no power adapter and you want to use the PoE feature. A few controller series like the 200 and 3000 Series do not support PoE. In this case, the AP cannot be terminated physically in the controller. Instead, connect the AP to the PoE switch, which is connected to the controller. Then assign a static IP configuration for the AP using the following commands:
    apboot> setenv ipaddr <ip address>
    apboot> setenv netmask <netmask>
    apboot> setenv gatewayip <ip address of the gateway>
    apboot> setenv master <ip address of the master>
    apboot> setenv serverip <ip address of the TFTP server>
    apboot> setenv bootcmd tftp
    apboot> save
    apboot> boot
    Locally configure the TFTP server for the AP and load the mips32.ari file from the controller with the help of the TFTP application.

    I want to download this file Mips32.ari for AP-105 device. Please give me this file download link. APBoot 1.2.4.4 (build 26618)

  • I have many photos that are visible as thumbnails in the Pictures Library, however when I try to open them in a big screen they show a back screen with an exclamation mark in a triangle.  What does this exclamation mark mean ?

    I can see my images in the libarary as thumbnails but when i try to edit/email some of them become Exclamation Marks in a triangle.
    What does the exclamation mark mean and how to i retrieve the photo

    The exclamation make is an indication that iPhoto has broken the file path to the original photo.
    Make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
    Fix #1
    Launch iPhoto with the Command+Option keys held down and rebuild the library.
    Select the options identified in the screenshot. 
    Fix #2
    Using iPhoto Library Manager  to Rebuild Your iPhoto Library
    Download iPhoto Library Manager and launch.
    Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
    Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
    In the next  window name the new library and select the location you want it to be placed.
    Click on the Create button.
    Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

  • What does this error message mean? (link to picture)

    My MacBook has been not working very well this morning, so I did the verify disk thing and it returned the message that something was corrupt and I had to start up from the Mac OS X installation DVD and repair the disk. What does the message here mean?

    OK, I'll try: it means that there's a missing directory record; that is, there's an item in the directory pointing to a record that doesn't exist. What else can I tell you? All such errors need repairing.

  • What does this popup message mean that I have been getting since the update

    I got the update the other day and now when I open some of my projects this message pops up twice
    "the previous selected audio interface is not available. Built in audio input and outputs of the computer will be used instead for this session".
    What does this mean? How will it affect my project? or should I just ignore it. I am assuming this must be caused by the new update, since it did it the next day when I opened one of my projects. thanks

    You could try to re-select your audio input and output settings under "Preferences > Audio" then save your song, quit and re-launch, and see if the message disappears. Maybe the update did something to your previous audio settings.
    Hopefully this helps.

  • What does this log entry mean  - Cancel initiated for Exchange Producer

    Is there anybody who can tell me what could this log entry mean:
    --Cancel initiated for Exchange Producer: <<66800621>> DbGateway Exchange*
    I'm asking because I have problem. In two physical sources (physical databases) I have two tables TABLE_1 has 60k rows TABLE_2 has 1 row. Next step these tables are "Binary Join" by BI server
    so it looks like here:
    -------------------- Sending query to database named OBI (id: <<66800621>>):
    select T7101.SYMBOL as c1,
    T7101.TABLE_1 as c2

    As you see first is executed select from TABLE_2 (Node: <<66800638>>, Close Row Count = 1) and this is correct number of close row count
    next we have
    Cancel initiated for Exchange Producer:(for node with SELECT ROM TABLE_2) - and I don't know what that's mean
    and after this we have
    Execution Node: <<66800621>> DbGateway Exchange, Close Row Count = 3
    And this is incorrect number of CloseRowCount (should be aprox. 60k)
    Finally result is wrong because we have no records (inner join by BI Server doesn't work :( )
    Thank you for help

    I'm wrestling with getting all of this to work myself.
    Can you see the job in XGrid Admin? It sounds as if the job is failing, but I can't be sure. Clicking on the job in XGrid Admin should give you a "play by play" and tell you where it is failing.
    My experience has shown me that permissions is the root cause of alot of issues, and I cannot find any clear reference on what permissions the "Podcasts" folder needs to make all of this work.
    Following the documentation, the "pcastxgrid" user doesn't actually get assigned any permissions via the file system or Group membership, so I'm not sure how all of this needs to be set.
    Hope this helps.

  • What does this error message mean? "An unexpected error occurred (error code -6584). It arises when I open my Time Capsule icon.

    I had a problem when downloading iTunes 11.1 and had to clear my disc and rebuild it from Time Capsule.  Thats when I learned that Time Capsule stopped backing up back in January.  So now I keep looking to see if Time Capsule is backing up but whenever I open the Time Capsule icon i get this error message.  What does it mean and how can I fix the problem?

    The backup is corrupted in some way.. you need to verify it.
    The error is common enough but there seems to be a range of solutions.
