How to read data from the PDF file

Hi
i need pdf related API details and sample program to retrive the data from the pdf.

Did you even try looking this one up yourself? Google "java pdf" and you get plenty of results. The first one looks pretty promising, and I'm sure there is plenty of documentation with the API.

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.

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?

Looking for pure Java API to read metadata from an MP4 file.

Hi, I am looking for a pure Java api that can read MP4 metadata. I have been trying to look online for one but have not found anything
suitable. If there are no good api's, can someone point me to resources on how to parse metadata from an MP4, tutorials would be great
as well. I have looked online for that as well but have not found much. Any help would be greatly appreciated.

Figuring out how to extract images from a PDF file

Hi,
I'm trying to write a small app that extracts all images from a PDF file. I already wrote a nice parser and it works good but the only problem is that I can't quite figure out from the reference how to decode all images in a PDF file to normal files such as tiffs, jpegs, bmps etc. For now I'm focusing on XObject images and not dealing with inline images.
From what I understand so far just by trying and looking at open sources I figured that if I see a XObject Image with a DCTDecode filter, taking the stream data without doing anything to it and saving it as a jpeg file works. But doing the same to FlateDecoded streams or CCITTFax didn't work.
What is the right way to properly extract the images?

In general you have to
* decode the stream
* extract the pixel data
* use ColorSpace, BitsPerComponent, Decode and Width to unpack pixel
values
* reconstruct an image file format according to its specification
There are no other shortcuts. The DCTDecode shortcut (which doesn't
work for CMYK JPEG files) is just a piece of fantastic good luck.

How to read,dispaly and open pdf files

Hi, I am very new to Java butI have VB6.0 background. My current requirement is to read pdf file names from a directory, then
show them on a form in a list (with their path in background pointing to the actual pdf files) and then once a user clicks any
file name, open that file on the form.
For example:
My pdf files are in a directory as following:
C:\myreports\user1\
report1.pdf
report2.pdf
report3.pdf
C:\myreports\user2\
report1.pdf
report5.pdf
The output on the form should look like this if user1 has logged in the system. Side note: I am able to get userid of the logged in person in a variable.
My Reports:
. Report 1
. Report 2
. Report 3
When a user clicks Report 1, it opens on the same form in pdf format.
Thanks
S.yhong

For the first part (Listing thepdf files in the directory) you can use the java.lang.File class.
File f = new File("path to your directory");
File files[] = f.listFiles();
then process the files array to find the files with extenction pdf
You can also use a file filter object and make the listFiles method return only the pdf files.
Please read the documentation about the File class for more info about it.
*/ For the displaying the pdf part is it good enough if you load the accrobat reader and with it. In that case you can do that using the Runtime.exec
Also you can search for free java based pdf viewers I am sure there must be meny.
And also the JTextPane might support pdf but I am not sure about it.
EDIT:
Just to say that this is my 1000th post :)

How to extract data from offline PDF files as batch processing

Hello.
I want to use Adobe Interactive forms as batch processing.
For instances,
1. Users download offline PDF files.
2. Users inputs data on their local PCs.
3. Users upload these PDF files in one folder.
4. Program can read data form PDF files on that folder. and put data to ERP at night.
I' d like to know how to implement a program with Java or ABAP.
Regards.
Koji.

Hi,
It's possible to do it but first be sure that the SAP system can read the directory while your program is executed in background .
Then you have to read the content of the directory and process each file you found.
Look at this standard ABAP object cl_gui_frontend_services , you will find method for browsing a directory and retrieve list of file .
Afterwards you have to process each file , for this have a look at this wiki code sample i wrote for processing inbound mail with adobe interactive form, it should help you [Sample Code for processing Inbound Mail with Adobe Interactive Forms|https://www.sdn.sap.com/irj/sdn/wiki?path=/display/snippets/sampleCodeforprocessingInboundMailwithAdobeInteractive+Forms]
Hope this help you .
Best regards.

How to read data from writable PDF Form?

Hi,
I need some help for the web site that I am working on.
This is asp.net website. Client is requesting to provide writeable PDF forms on this website for download.
These forms will be downloaded by customers, they will fill in the required data on these forms save it and upload the forms back on the website.
Once uploaded we need to read whtever client has written in these forms and update in the database (SQL server).
I have been going through adobe web site and lot of other web sites to understand this concept (as i have never done this).
What I understood is, with Adobe LiveCycle designer and forms we can create writeable forms.
However I have not got any idea or seen any documentation on how do I read the data that user has typed on these forms.
This reading the data from pdf and saving into sql server, I have to do it in asp.net app.
Could anyone please help me understand how to achieve this.
Thanks a lot for you time.

How do we do that?
Just to clarify myself, I am not putting any button on PDF to invoking submit action from PDF. I am allowing user to upload the pdf and they click submit button on my aspx page.
Are you saying that when user submits the aspx page there is a wasy to retrieve the data in the form of XML or name/value pair on this aspx submit? if so please send me some pointers/examples or let me know how to do this? Is there any additonal tools/software that we will need to buy from adobe for this?
thanks for you time!

How to read data from many excel files

I'm aquiring data continusly from several sensors, and every days file name are changed. Data are saved on xls files.
Now, I'd like to read every data from this files and put them in a waveform. How can I concatenate all files and read the values?

You probably do not want to use a traditional waveform. LabVIEW has a Waveform Chart which inputs one point at a time. Waveform Graph inputs an array.
I suspect that the data is stored in an array. You need to read the arrays in and build them into larger arrays. If your right click on the build array vi, you can select concantenate which will append one array to the end of the other. When you have built your giant array, just feed it to a waveform graph.
If you need to see some example code, go to the advanced search page. It is at www.ni.com >> support >> advanced search (it is at the botton--click on the words). Enter excel read in the all the words field and search just the example programs. There were for hits.

How to read characters from a text file in java program ?

Sir,
I have to read the characters m to z listed in a text file .
I must compare the character read from the file.
And if any of the characters between m to z is matched i have to replace it with a hexadecimal value.
Any help or suggesstions in this regard would be very useful.
Thanking you,
khurram

Hai,
The requirement is like this
There is an input file, the contents of the file are as follows, you can assume any name for the file.
#Character mappings for Japanese Shift-JIS character set
#ASCII character Mapped Shift-JIS character
m 227,128,133 #Half width katakana letter small m
n 227,128,134 #Half width katakana letter small n
o 227,129,129
p 227,129,130
q 227,129,131
r 227,129,132
s 227,129,133
t 227,129,134
u 227,129,135
v 227,129,136
w 227,129,137
x 227,129,138
y 227,129,139
z 227,129,142
The contents of the above file are to be read as input.
On encountering any character between m to z, i have to do a replacement with a hexadecimal code point value for the multibyte representation in the second column in the input file.
I have the code to get the unicode codepoint value from the multibyte representation, but not from a file.
So if you could please tell me how to get the characters in the second column, it would be very useful for me.
The character # is used to represent the beginning of a comment in the input file.
And comment lines are to be ignored while reading the file.
Say i have a string str="message";
then i should replace the m with the unicode code point value.
Thanking you,
khurram
