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
Regards

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,

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;
catch
return pageText; -
how to edit text from pdf file?
Adobe Reader does not allow editing the text of a PDF document. You will need to get Acrobat on your Windows or Mac to do that.

Extracting Images from PDF file
Hello All,
I am reading PDF File.I need to extract images from PDF File programatically.But problem is that some images are stored inside PDF File using FlateDecode Filter and I need to first decode that file and then I can extract that image .I dont know the way to decode that image data.Is there any way or API to do that in C++.
Thanks
Aarti NagpalI think you can do it through cos object in VC++ plugin..go through the PDEFilterSpec in
Acrobat core api reference
Be well.. -
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.

Does IBR support to extract text from office files
hi Experts,
Can we use IBR to extract word/excel/ppt content to a text file? where is doc for this function?
Best regardsHi ,
Extraction of text based on some rules ?Is that what you are looking for ? Is it for searching on those specific set of texts from the file ? If yes , then you have Oracle Text search feature which would do that .
If it is to populate some metadata with those extracted texts , then it would be Content Categorizer component . For details on this component and it's functionality please go through the following documentation : http://docs.oracle.com/cd/E14571_01/doc.1111/e10978/c11_content_categorizer.htm#sthref1210
In either cases , IBR is not the actual engine which would do this . It is solely used for document conversion . \
Hope this helps .
Thanks,

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.

Extracting pages from PDF file and creating new subfile PDF
I am a .NET C# developer looking into creating an app that extracts a subset of pages from a PDF document, say, given a start and end page number, and possibly creating a new PDF file with that subset of pages. Is there a convenient way of doing this ?
Ok. The Acrobat SDK is not directly going to help, because the Acrobat SDK requires Acrobat, and Acrobat is not for server use.
Adobe have the Adobe PDF Library for server use. C/C++, there may be a Java interface too from DataLogics, but huge overkill for this task, and many find it rather pricy for a simple task like this. There are third party libraries and tools, but this is not the place to discuss them. -

Extract text from PDF and parse to Excel, automator? applescript?
