How to read line number text from PDF using plugin?

Hi, I would like to know how to read line number text from PDF using plugin?
Thanks in advance.

Ok, some background reading of the PDF Reference will help you understand why this is so difficult. PDF files are not organised into lines. It is best to think of each word or character on the page as being a graphic with its own position. The human eye sees lines where a series of graphics (words) are roughly in the same horizontal region.
In the general case it is difficult or even impossible to answer this. You may have columns with different spacing (but the PDF stores no information on what is a column). You may have subscripts and superscripts. You may have text in graphics coinciding with other text. Commonly, there may be titles, headings or page numbers which are just ordinary text and might count as lines.
That said, what you need to do is extract the text on the page and its positions. The WordFinder APIs are the way to do that. Now, sort all the words out, using the Y coordinates and size to try and guess what makes a "line". Now you are in a position to find the text (divided into words, not strings) and report the "line number" you have estimated.

Extract Text from pdf using C#

Hi,
We are Solution developer using Acrobat,as we have reuirement of extracting text from pdf using C# we have downloaded adobe sdk and installed. We have found only four exmaples in C# and those are used only for viewing pdf in windows application. Can you please guide us how to extract text from pdf using SDK in C#.
Thanks you for your help.
Regards
kiranmai

Okay so I went ahead and actually added the text extraction functionality to my own C# application, since this was a requested feature by the client anyhow, which originally we were told to bypass if it wasn't "cut and dry", but it wasn't bad so I went ahead and gave the client the text extraction that they wanted. Decided I'd post the source code here for you. This returns the text from the entire document as a string.
 private static string GetText(AcroPDDoc pdDoc)
 AcroPDPage page;
 int pages = pdDoc.GetNumPages();
 string pageText = "";
 for (int i = 0; i < pages; i++)
 page = (AcroPDPage)pdDoc.AcquirePage(i);
 object jso, jsNumWords, jsWord;
 List<string> words = new List<string>();
 try
 jso = pdDoc.GetJSObject();
 if (jso != null)
 object[] args = new object[] { i };
 jsNumWords = jso.GetType().InvokeMember("getPageNumWords", BindingFlags.InvokeMethod, null, jso, args, null);
 int numWords = Int32.Parse(jsNumWords.ToString());
 for (int j = 0; j <= numWords; j++)
 object[] argsj = new object[] { i, j, false };
 jsWord = jso.GetType().InvokeMember("getPageNthWord", BindingFlags.InvokeMethod, null, jso, argsj, null);
 words.Add((string)jsWord);
 foreach (string word in words)
 pageText += word;
 catch
 return pageText;

Reading line item text from sales order

Hi,
I have a sales order which has an item text, I need to get the value from the text. I want to test the READ_TEXT function and I am giving values as
Import parameters               Value
CLIENT                          400
ID                                  0011
LANGUAGE                   EN
NAME                            0001171445000010
OBJECT                         VBBP
ARCHIVE_HANDLE         0
LOCAL_CAT
It is not giving me any value. Am I giving any thing wrong? In the NAME I gave the value as sales ord num + item number, is this correct. Please help me.
Thanks,
Veni.

Hi
Name is the Concatenation of Order No and Item No.
pass the 4 parameters ID,OBJECT,NAME and LANG
use the correct declarations for the parameters and use
ID = '0011'
LANGUAGE = 'EN'
NAME = '0001171445000010'
OBJECT = 'VBBP'
See the doc
READ_TEXT
READ_TEXT provides a text for the application program in the specified work areas.
The function module reads the desired text from the text file, the text memory, or the archive. You must fully specify the text using OBJECT, NAME, ID, and LANGUAGE. An internal work area can hold only one text; therefore, generic specifications are not allowed with these options.
After successful reading, the system places header information and text lines into the work areas specified with HEADER and LINES.
If a reference text is used, SAPscript automatically processes the reference chain and provides the text lines found in the text at the end of the chain. If an error occurs, the system leaves the function module and triggers the exception REFERENCE_CHECK.
Function call:
CALL FUNCTION 'READ_TEXT'
EXPORTING CLIENT = SY-MANDT
OBJECT = ?...
NAME = ?...
ID = ?...
LANGUAGE = ?...
ARCHIVE_HANDLE = 0
IMPORTING HEADER =
TABLES LINES = ?...
EXCEPTIONS ID =
LANGUAGE =
NAME =
NOT_FOUND =
OBJECT =
REFERENCE_CHECK =
WRONG_ACCESS_TO_ARCHIVE =
Export parameters:
CLIENT
Specify the client under which the text is stored. If you omit this parameter, the system uses the current client as default.
Reference field: SY-MANDT
Default value: SY-MANDT
OBJECT
Enter the name of the text object to which the text is allocated. Table TTXOB contains the valid objects.
Reference field: THEAD-TDOBJECT
NAME
Enter the name of the text module. The name may be up to 70 characters long. Its internal structure depends on the text object used.
Reference field: THEAD-TDNAME
ID
Enter the text ID of the text module. Table TTXID contains the valid text IDs, depending on the text object.
Reference field: THEAD-TDID
LANGUAGE
Enter the language key of the text module. The system accepts only languages that are defined in table T002.
Reference field: THEAD-TDSPRAS
ARCHIVE_HANDLE
If you want to read the text from the archive, you must enter a handle here. The system uses it to access the archive. You can create the handle using the function module ACHIVE_OPEN_FOR_READ.
The value '0' indicates that you do not want to read the text from the archive.
Reference field: SY-TABIX
Default value: 0
Import parameters:
HEADER
If the system finds the desired text, it returns the text header in this parameter.
Structure: THEAD
Table parameters:
LINES
The table contains all text lines that belong to the text read.
Structure: TLINE
Exceptions:
ID
The text ID specified in the parameter ID does not exist in table TTXID. It must be defined there together with the object of the text module.
LANGUAGE
The parameter LANGUAGE contains a language key that does not exist in table T002.
NAME
The parameter NAME contains the name of a text module that does not correspond to the SAPscript conventions.
Possible errors:
The field contains only blanks.
The field contains the invalid characters * or ,.
OBJECT
The parameter OBJECT contains the name of a text object that does not exist in table TTXOB.
NOT_FOUND
The system did not find the specified text module.
REFERENCE_CHECK
The text module to be read has no text lines of its own but refers to the lines of another text module. This reference chain can include several levels. For the current text, the chain is interrupted, that is, one of the text modules referred to in the chain no longer exists.
WRONG_ACCESS_ TO_ARCHIVE
The exception WRONG_ACCESS_TO_ARCHIVE is triggered if an archive is accessed using an incorrect or non-existing archive handle or an incorrect mode (that is, read if the archive is open for writing or vice versa).

Can't seem to save non-English as text from PDF using Reader

I have several PDF documents that were originally generated by OpenOffice from a UTF8-encoded text file. The text is in different languages, e.g. Korean, Arabic, Russian, English. When I open these documents and then "save as text", the resulting text files contain garbage or nothing at all in all cases except for English. Is it possible to extract non-English text from a PDF document using Reader? If not, is there a different product that could be used for this purpose? Thanks much!

They're using fonts that you don't have on your system so no, it isn't possible with Reader.

How to read a local file from Forms10g using PJC/Bean

I'm trying to read a file on the client machine using a Bean.
The code in the Bean is:
File fp = new File(mFileName);
printToConsole( "AFTER creating a File object " );
if (fp.exists())
I get the message after creating File object. But at the next statement - fp.exists() - the Forms session terminates giving a FRM-92100 - Your connection to the server was interrupted.
Any ideas?
Thanks in advance for your help.
Amit

Frank, Thank you for your response on signing the jar. That was exactly what I was missing. After signing the jar, I am able to do client level operations.
Grant, Thank you for asking about WebUtil. To give you a background as to what we are trying to do - to integrate our Forms 10g application with another software - in this case a client-server app. We want to send a message from this app. to our Forms10g app.(a pre-defined Form in the app.) which would initiate certain Forms navigation based on the message. In essence, Forms needs to be "listening" to this app. (in a non-blocking mode, the Forms app. should not be "locked-out" while listening for a message)
The only way I could think of was to write a Bean (modified version of Frank's Dispatch Event sample on his blog) which would spawn a thread and listen for a message from the other app. For our prototype, I started off with watching for a file on the client machine. The final goal is to listen for a message on MQ. This will facilitate us to integrate our Forms10g app. with any other app.
Regarding WebUtil, I did not find a way to do the listening/polling in a non-blocking way. Maybe I must have missed the obvious - Frank can very well attest to that.
Any feedback is most welcome.
Thanks.
Amit

How 2 Copy Header & Line Item Text from Purchase Order 2 Out Bound Delivery

Hi SD Gurus,
I want to copy header and line item text from Purchase Order to Out Bound Delivery (This is required in Stock Transfer Process).
I have been able to do successful config. for copying header and line item text from Sales Order to Outbound Delivery but config. doesn't seems to be same for copying text from PO to OBD.
Is there any way to achieve the same? Can some expert show the way to achieve this.
Thanks in advance.
Warm regards,
Rahul Mishra

Hi Ravikumar thanks for u quick reply.
This is wht is currently coded.
concatenate values to get item text for read text function
   invar3+0(10) = invar1. "PO number
   invar3+10(5) = invar2. "PO line number
   SELECT SINGLE * FROM stxh WHERE tdobject = 'EKPO'
                               AND tdname   = invar3
                               AND tdid     = 'F01'
                               AND tdspras = sy-langu.
   IF sy-subrc = 0.
     invar4 = invar3.
reading the text for the document items.
     CALL FUNCTION 'READ_TEXT'
       EXPORTING
         id       = 'F01'
         language = sy-langu
         name     = invar4
         object   = 'EKPO'
       TABLES
         lines    = it_itab.
I have seen some PO's which have info rec texts in that, which gets pulled by the above code...first thing is its id is F02 which exist in STXH table also there is other text with F01 id, and hence the table it_itab gets both these text hence no pbm.
but i came across a PO which has only one text which is info rec text with id F05 and is not store in stxh and hence doesnot get pulled by read_text fm. How do i change my cod to get this text which should not hamper other PO's as well.
As mentioned in above msgs, this F05 could be retrieved by providing object name as EINE.
anyhelp will be appreciated and rewarded.
thanks

How can I Read lines of data from a file starting at the end of the file??

Can anyone help me with how to read lines of data starting from the end of a file instead of the beginning?? I do not want to load the entire file into memory as the files are very rather large. Instead I want to start at the end of the file and read lines backward , until I find the particular data item i am searching for, then stop.
Can this be done in Java ? I know it can be done in Perl.
Thanks.

Thanks for your suggestion about the RandomAccessFile, I did actually thought about that approach , but wasn't sure it would work.
I do not want to read the file in a sequential forward manner because the files contain large number of lines of data that have already been processed and therefore there is no need to reprocess these lines of data.
The Unprocessed lines are always at the the end of the file and these are the data lines I am interesting in getting at without having to read the entire file. Therefore, i figure that if I can read the data from the end of the file then this would be much more efficient.

How to read a whole text file into a pl/sql variable?

Rishi,
Welcome to Apple Discussions.
After reading your post, I tried to duplicate this problem. I opened a PDF, selected a sentence, then copied it to the clipboard. I then opened Pages, selected the blank template, then pasted in the text. It pasted perfectly.
Does this problem happen with all text in a PDF? With different PDFs?
