Extract text from PDF without opening PDF in window C#
Hello,
I'm creating a application for searching text in PDF's. I found some code wich uses the SDK from Acrobat (Installed on my system). But all the snippets I find seem to open a PDF window and then extract the text. Is it possible to extract the text without openening this window. I think this would increase the search time since I need te search a lot of files. And I just need a list with the file name and page number where the search string is found.
AcroAVDoc avDoc = (AcroAVDoc)gAppClass.GetInterface("Acrobat.AcroAVDoc");
Then I use the javascript obects to acces the "getPageNumWords" and "getPageNthWord" in a loop and putting the word in a string.
Thanks in advance fore the help.
I didn't want to put the entire code here because it's easely found all over the web
Thanks in advance for your help.
avDoc.Open(System.IO.Path.GetFullPath(filespec), filespec);
Hello,
I own a copy of Acrobat pro 9. and its is for my own use. I am not a proffesional developper and this application wil not be distributed.

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
kiranmaiOkay 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;

Applescript or workflow to extract text from PDF and rename PDF with the results
Hi Everyone,
I get supplied hundreds of PDFs which each contain a stock code, but the PDFs themselves are not named consistantly, or they are supplied as multi-page PDFs.
What I need to do is name each PDF with the code which is in the text on the PDF.
It would work like this in an ideal world:
1. Split PDF into single pages
2. Extract text from PDF
3. Rename PDF using the extracted text
I'm struggling with part 3!
I can get a textfile with just the code (using a call to BBEDIT I'm extracting the code)
I did think about using a variable for the name, but the rename functions doesn't let me use variables.Hello
You may also try the following applescript script, which is a wrapper of rubycocoa script. It will ask you choose source pdf files and destination directory. Then it will scan text of each page of pdf files for the predefined pattern and save the page as new pdf file with the name as extracted by the pattern in the destination directory. Those pages which do not contain string matching the pattern are ignored. (Ignored pages, if any, are reported in the result of script.)
Currently the regex pattern is set to:
/HB-.._[0-9]{6}/
which means HB- followed by two characters and _ and 6 digits.
Minimally tested under 10.6.8.
Hope this may help,

Hi, is it possible to extract text from a pdf file using the command line to get an output like you would get by using the File menu and then 'Save as text..."?
I also noticed that in the installation folder there is a small executable called AcroTextExtractor which sounds interesting, but I was unable to figure out how to use it.what's wrong with using automator for this? this certainly seems the easiest. I'm not aware of any built in apple script commands that will do this. But You should also ask on the Apple script forum under Mac OS Technologies.

Extracting text from PDF in columns?
I'm trying to extract the text from a number of PDFs in which the text is in two columns. When I copy the txt and paste it into Word, it ends up being in a single column, the width of one of the original columns, but with a hard return at the end of each line.
I don't really care if the extracted text ends up being in one column or two, I just want it not to have a return at the end of each line. Can anyone suggest an alternative method?i get the following error message:

Extracting text from PDF files produced by Oracle reports
Hi,
I am currently using Report Builder 9.0.4.0.21 to produce reports in PDF format.
The pdf reports were displayed to screen and printed to printer correctly.
However, doing a copy-and-paste from the pdf report to a text editor produces
garbage characters. Also, I failed to extract the text using any of available adobe
plug-ins. I know that the PDF report is using font subseting with custom
encoding.I have already read the pdf reference manual and it seems that
the PDF report is missing the mapping tables to convert the custom encoding
used in the report back to ansi or unicode.
Is there a solution to this problem?
Are there any environment variables or settings that I am missing?
Your help is really appreciated.Hello,
Your problem may be related to a limitation in the PDF generated with Reports 9.0.2 / 9.0.4 when using Subsetting :
Font Subsetting Creates PDF Output not Searchable with Acrobat Reader (Doc ID 311345.1)
This limitation no more exists in Reports 10.1.2 / 11.1

Extract text from PDF and parse to Excel, automator? applescript?
I'd been trying to do this with automator and have been getting nowhere.
I have some pdf files that have selectable, formatted text in them.
Its an old college directory that I would like to import. There are chunks of text:

I'd like to find a way to extract the names, the phone numbers, and the hometowns and get it all into those respective columns in excel. Seems that I don't stand a chance with automator. Do I need a programmer for this?I'd been trying to do this with automator and have been getting nowhere.

How to extract text from a PDF file?
Hello Suners,
i need to know how to extract text from a pdf file?
does anyone know what is the character encoding in pdf file, when i use an input stream to read the file it gives encrypted characters not the original text in the file.
is there any procedures i should do while reading a pdf file,
File f=new File("D:/File.pdf");
FileReader fr=new FileReader(f);
BufferedReader br=new BufferedReader(fr);
String s=br.readLine();any help will be deeply appreciated.jverd wrote:
First, you set i once, and then loop without ever changing it. So your loop body will execute either 0 times or infinitely many times, writing the same byte every time. Actually, maybe it'll execute once and then throw an ArrayIndexOutOfBoundsException. That's basic java looping, and you're going to need a firm grip on that before you try to do anything as advanced as PDF reading. the case.oops you are absolutely right that was a silly mistake to forget that,
Second, what do the docs for getPageContent say? Do they say that it simply gives you the text on the page as if the thing were a simple text doc? I'd be surprised if that's the case.getPageContent return array of bytes so the question will be:
how to get text from this array? i was thinking of :
private void jButton1_actionPerformed(ActionEvent e) {
PdfReader read;
StringBuffer buff=new StringBuffer();
try {
read = new PdfReader("d:/getjobid2727.pdf");
read.getMetaData();
byte[] data=read.getPageContent(1);
int i=0;
while(i>-1){
buff.append(data);
i++;
String str=buff.toString();
FileOutputStream fos = new FileOutputStream("D:/test.txt");
Writer out = new OutputStreamWriter(fos, "UTF8");
out.write(str);
out.close();
read.close();
} catch (Exception f) {
f.printStackTrace();
"D:/test.txt" hasn't been created!! when i ran the program,
is my steps right? -

Imac Mac OS X (10.4.7)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?
