Making text in a PDF darker???

Is the only way to make text in a PDF darker to use Document-->OCR Text Recognition-->Recognize Text Using OCR and then use the ClearScan PDF Output Style?

This presumes you have access to the original paper so you can rescan it. If you don't, are there any levels/contrast adjustments avaible in AA9 though? (I haven't seen any.)

Inserting text to Acrobat PDF document, not able to create PDEText.

Hi ,
I have created a plugin for Acrobat, On press of MyPlugin's 'Insert' button it has to add the text to the document.
Eg: If there is a Active PDF document, which contains a text "Hello" in it. I want to insert "World" (i.e, the document should have "Hello World") when i click 'Insert' button.
I am writing the below function for this:
static void InsertCitationText(PDDoc activePDDoc,PDPage pdPage , int pgNum , int pgOffset)
      PDEContent volatile pdecontent = NULL;
      PDPage pdPage = PDDocAcquirePage (activePDDoc, pgNum);
      pdecontent = PDPageAcquirePDEContent (pdPage, gExtensionID);
    Here I have to create PDEText pdeText and assign "World" to it. How do i do this??
     I tried to do this in TextCreate function by looking into the sample plugin snippets but its not creating the text , when i debug and see the value value of 'pdeText' its giving, "pdeText not found".
           PDEText pdeText = TextCreate();
      PDEContentAddElem(pdecontent, kPDEAfterLast, (reinterpret_cast<PDEElement>(pdeText)));
      /* Put the contents back in the page */
      PDPageSetPDEContent(pdPage, gExtensionID);
      /* Clean up */
      PDPageReleasePDEContent(pdPage, gExtensionID);
static PDEText TextCreate()
            PDSysFont sysFont=NULL; /* Used by PDEFont creation */
            PDEFont pdeFont=NULL; /* Reference to a font used on a page */
            PDEFontAttrs pdeFontAttrs; /* Font attributes */
            ASFixedMatrix textMatrix; /* Transformation matrix for text */
            PDEColorSpace pdeColorSpace; /* ColorSpace */
            PDEGraphicState gState; /* Graphic state to apply to operation */
            // Create a PDEText object
            PDEText pdeText = PDETextCreate();
            // Text to write to the PDF
            char *Title = "World";
            // Get system font
            sysFont = PDFindSysFont(&pdeFontAttrs, sizeof(PDEFontAttrs), 0);
          // Initialize the font descriptor then create the font reference.
            memset(&pdeFontAttrs, 0, sizeof(pdeFontAttrs));
            // Find the matching system font.
            pdeFontAttrs.name = ASAtomFromString("Verdana");
            pdeFontAttrs.type = ASAtomFromString("Type1");
            //Get system font
            sysFont = PDFindSysFont(&pdeFontAttrs,sizeof(pdeFontAttrs),0);
            pdeFont = PDEFontCreateFromSysFont(sysFont, kPDEFontDoNotEmbed);
            // Create a DEGraphicState object and set its attributes
pdeColorSpace = PDEColorSpaceCreateFromName(ASAtomFromString("DeviceGray"));
            memset(&gState, 0, sizeof(PDEGraphicState));
gState.strokeColorSpec.space = gState.fillColorSpec.space = pdeColorSpace;
            gState.miterLimit = fixedTen;
            gState.flatness = fixedOne;
            gState.lineWidth = fixedOne;
            // Create an ASFixedMatrix object
            memset(&textMatrix, 0, sizeof(textMatrix));
            textMatrix.a = Int16ToFixed(24);
            textMatrix.d = Int16ToFixed(24);
            textMatrix.h = Int16ToFixed(1*72);
            textMatrix.v = Int16ToFixed(2*72);
            //Create a PDEText Object
            pdeText = PDETextCreate();
PDETextAdd (pdeText, kPDETextRun, 0,(ASUns8 *)Title, strlen(Title), pdeFont, &gState,
            sizeof(gState), NULL, 0, &textMatrix, NULL);
            PDERelease ((PDEObject) pdeColorSpace);
            PDERelease ((PDEObject) pdeFont);
            return pdeText;
Is there anyway i can add the "World" (as PDEElement) to document so that i can use in this function "PDEContentAddElem(pdecontent, kPDEAfterLast, (reinterpret_cast<PDEElement>(pdeText)));" ???
Or
Should i use the above 'TextCreate()' huge function to create PDEText(PDEElement). If i have to use this method why the PDEText is not getting created? Am i missing something in the above function ??
Please someone help me out, Thanks in advance.

Chetan.

Hi Irosenth,
I will give a try for this, we must try to certain extent who knows we may Succeed. We must noe give-up easily.
You have not said this is impossible, but you say this is difficult. Rite ??
If you give me support, i dont think it would be difficult.
First i will try to insert a text in a blank page.This is possible rite ??
I saw a discussion in this forum, http://forums.adobe.com/message/2092443#2092443 , this is 2 years old. This guy has inserted the text into PDF document.
I refered this link and try to insert a text in Active PDF document but text is not getting inserted into it.
Please let me know what i am making wrong in the below function,
static void InsertCitationText(PDDoc activePDDoc, int pgNum , int pgOffset)
      PDEContent volatile pdecontent = NULL;
      PDPage pdPage = PDDocAcquirePage (activePDDoc, pgNum);
      pdecontent = PDPageAcquirePDEContent (pdPage, gExtensionID);
      PDEText pdeText = TextCreate();
      PDEContentAddElem(pdecontent, kPDEAfterLast, (reinterpret_cast<PDEElement>(pdeText)));

      PDPageSetPDEContent(pdPage, gExtensionID);
      /* Clean up */
      PDPageReleasePDEContent(pdPage, gExtensionID);
TextCreate() function is same as the one which i mentioned in this discussion. Please let me what i am making wrong in that function aswell. Its not creating the specified "World" pdeText. Please help me out for this. Thanks in advance.

Imbedding text in a pdf

How do you imbed text in a pdf created in Aperture 3 for a photo book?

Thanks for your reply. Sorry I wasn't specific enough. I've already put together the photo book in Aperture, text and all, and converted it to a pdf. The printing service I'm using (which prints a lot of iphoto & aperture photo books) said that the text has to be imbedded in the pdf, which makes it sound like that is not necessarily the default when making a pdf. Do you know whether or not the text imbedding is an additional step and how to do that? I have never made a photo book before, so this is all new to me.
Thanks,

Globally delete text from a PDF?

Hi,
Firstly, my apologies for wading in with a question that may have been asked. The forum search didn't turn it up but I'm not sure I searched with the right terms.
I'm trying to remove all the text from a PDF to leave the vector images behind - that way I can use the images as a test. I don't mind if it's a solution like making all the text white, just as long as it's invisible in the document.
I had thought this would be reasonably straightforward but I've been looking around for about a day now and no luck. I installed the pdfbox library which had an example code snippet to do this, but my abilities ran short.
Any ideas?
I'm using Acrobat 9 Pro v9.4.6 on Mac OS X 10.7.2 if that helps.
Thanks for reading, and for any help.
Cheers,
Matthew.

George - THANK YOU!
When I pulled up the Profiles in the Preflight dialog, under Create PDF Layers there is a setting for "Put all text objects on a layer". I double-clicked this, gave it an output file name and off it went - lifted out tens of thousands of text objects from a several-hundred page PDF. Took an hour or so - but not too bad after all that searching and hassle. The layer turns off nicely - I presume that will carry over when I print it!
I had no idea that Preflight was capable of this kind of manipulation, but in hindsight it makes sense.
THANK YOU again.

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?

Hi
I've a big problem with adobe acrobat reader XI pro and I hope you can help me.
The problem is; when I past copied text from some pdf books (not all of them) it past symbols only! wherever I past it! and even if I coped that text from another pdf reader (adobe pdf reader, internet browsers, ...etc.).
This problem started to happen since yesterday when I installed adobe acrobat reader XI pro to try it before I buy it, and before that when I was using the free adobe pdf reader I was totally able to copy any text from any pdf and past it anywhere with nothing wrong.
What can I do?
thank you a lot.

There is no product called Adobe Acrobat Reader Pro. There is
- Adobe Acrobat Pro ($$)
- Adobe Reader (free)
Which do you have? And are you a programmer?

I can't edit text on a pdf file in adobe acrobat

I need to edit the text on the pdf file but I can't and this message keeps showing up: " This form cannot be edited in Acrobat. Please use Adobe LiveCycle Designer to edit this form.
There are no security on this file. The only thing that is not allowed is to create templates. When I check the document properties description, on the PDF producer it says adobe distiller 7.0.5 (windows)
I downloaded the adobe livecycle designer but I couldn't edit the text there either... When I open the file it says the text is not downloaded so it replaced it with another text, I clicked ok but then the text didn't change, This message showed up:
I really need to edit the text on this pdf file because it's important. Can anyone help? Greatly appreciate it. By the way, this is a pdf fillable form that you can fill out on acrobat and that is the only thing it seems like it will let me do this file. I don't want to fill it out, I want to edit whats on it. It's one of those forms that you get from NJ courts.

Ok, what we can tell you is that if this is a LiveCycle form (and we can be pretty sure it is), that you are absolutely right. Acrobat can fill it, and nothing else. These are a very special kind of PDF, where all the text is in a special XML format that Acrobat can only show, not edit.
So, you are on the right track: if it can be edited, you need LiveCycle Designer. Unfortunately, we don't know much about it in this forum, so please try posting here: http://forums.adobe.com/community/livecycle/livecycle_modules_and_development_tools/livecy cle_designer_es

, Trouble importing from text file into PDF Acrobat 9.0

Hey all!
I'm trying to use the JavaScript found on this Adobe page to insert text into my PDF:
http://help.adobe.com/livedocs/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/wwhelp/wwhimpl/common/h tml/wwhelp.htm?context=Acrobat9_HTMLHelp&file=JS_API_AcroJS.88.502.html
this.importTextData("/c/data/myData.txt", 0);
Replacing the path with my own path, of course. However, I can't get it to work at all, it just crashes my JavaScript. I was thinking it might have something to do with the privilege stuff which, admittedly, confuses me a bit. But my understanding is that if you use the function without arguments, that shouldn't matter, and it will prompt the user for a path?
this.importTextData();
However, that still crashes the JavaScript. I'm not sure what exactly I am doing wrong here?
NOTE: I have tried running the JavaScript both in a checkbox and on page load.

Well I was having trouble getting it to work without a path, though that kind of mysteriously started working now despite the fact that I didn't really change anything. I also assumed that part didn't apply to me because we are on 9, not 8, but maybe it means 8 and on?
I'm having a bit of trouble wrapping my mind around privileged and non-privileged contexts.
These methods can be executed only in a privileged context, which includes console, batch and application initialization events.
What would be the simplest way to execute in a privileged context? "Application initialization" sounds promising, does this mean when the application is first opened? If so, how would you execute JavaScript this way?!

Is there a way to control Adobe PDF plugin from within a Web Application? For Example, Can we highlight text in the PDF/A document programatically?

Hi,
I am trying to open a PDF document in browser using Adobe PDF plug-in for IE 9. The plugin version is 10.x
I need to highlight certain text in the PDF document ( which is searchable) programmatically. For example, when a user selects certain text on the web-page, we want to automatically highlight that in the PDF document.

I don't think this is a question one can answer by simply downloading the SDK. And even if one reads all the documentation (it rarely happens for obvious reasons), it is not easy to reach an answer because its explanation is not trivial at all.
In my own opinion, this is right the type of question to be put and (hopefully) answered in a Forum.
Now, I am not sure about the correct answer but I will give one hint.
If I am not wrong, the Internet Explorer, IE, PDF viewer by Adobe is actually a .dll file which is put under IE once Adobe Reader is installed. A custom plug-in for Reader or Acrobat is also a .dll file (Windows) but its extension is .api and it needs to be copied under Reader or Acrobat (or both). Therefore, I don't see how we can merge the IE viewer .dll with a custom plug-in .api. Though maybe technically possible, I don't think it is something we can do.
If above reasoning is correct, the answer to the question is No.

Can you edit the text of a PDF that is placed in inDesign

I have placed a PDF in inDesign and am curious if I can edit the text of that PDF while in inDesign.

Edit it with Adobe Acrobat Pro, indesign can't. Option for Indesign is:
of course overlay text with new text
There is specialized software for editing PDF files, though the choices are much more limited and often more expensive than creating and editing standard editable document formats. Version 0.46 and later of Inkscape allows PDF editing through an intermediate translation step involving Poppler.
Serif PagePlus can open, edit and save existing PDF documents, as well as publishing of documents created in the package.
Enfocus PitStop Pro, a plugin for Acrobat, allows manual and automatic editing of PDF files, while the free Enfocus Browser makes it possible to edit the low-level structure of a PDF.
In Acrobat you should use the TouchUp Text Tool.
But in the end, PDF-files are not made for editing.

Using browser javascript to copy selected text from a pdf file opened in Air app.

I have posted this question on reader forum as well, but I think it is more suited here...
I am trying to create a note-taking application in air. I want to extract selected text from pdf file as a string object or to the clipboard.
Obviously, all pdfs in my local storage will not be scripted to recieve postMessages and act accordingly, and that is not practical either. So, my problem is, how can I copy the selected text in the pdf file (opened as an object in htmlloader within my Air app) to clipboard or directly in another control by say clicking a button in air application? I suppose, this is possible using javascript, however, I don't know which reader methods are exposed to the wrapper htmlloader control. In short, I want to execute app.execMenuItem("Copy") command through htmlloader javascript. Any alternate solutions are also welcome.
This is similar to passing inbuilt commands/methods/functions (of adobe reader) to pdf-reader plugin embedded in a webpage via javascript. This is possible in IE where the pdf is rendered as activex object, and hence JSObject interface of pdf document/reader is accessible to the browser javascript. I have also read that this same JSObject is accessible to VB as interface for IAC, so as the Air is Adobe's own product, I was wondering if equivalent of JSObject is accessible to htmlloader control as well.
Thanks in advance...
Mits

Thank you Thom for your reply...
from
http://www.adobe.com/devnet/acrobat/javascript.html
...Through JavaScript extensions, the viewer application and its plug-ins expose much of their functionality to document authors, form designers, and plug-in developers...
As it is explicitly mentioned, that the functionality of adobe reader are exposed for plugin development, I thought someone here might have used external javascript to execute some safe methods in adobe reader. The functionality (i.e. external javascript interface-JSObject) is already available for VB programmers to develop IAC. Further, the Acrobat SDK example called "AcroPDFinHML" shows how one can embed a pdf-reader in a html page and execute some safe methods (like gotonextpage(), zooming etc.) in IE as ActiveX plugin. I have checked it myself for adobe reader 9, and it works perfectly, so there is no security issue as such to implement the same for another browser (like in my case, the htmlloader control in flex/air app).
I intend to create a note taking application in air, where it is very much required that I should be able to copy selected text from various pdf documents, that are open in my app, and subsequently paste/collect/save the collected notes and process them afterwords (offcourse, from the pdfs that allow me copying text). However, it is not happening for me here. As the pdfs are opened through adobe reader plugin, it does not register the copy command executed by my air app. It registers the system level copy command (by keyboard shortcut Ctrl+C), but my air app has no way to execute the system level copy command programmatically. So I am kind of stuck here...
Thanks again for your reply. Having known what am I intend to accomplish, any other (may be alternative) solutions will be appreciated nonetheless...

Why Acrobat x professional is changing the text formatting specifically the font family and the font size of the text in my pdf on exporting it to Microsoft word file format ?How should i stop Acrobat x professional from doing that so that i get an exactly same word file on exporting it from its pdf counterpart?

I was testing the preciseness & efficiency of Adobe acrobat x professional's doc conversion capabilities. As i have to take a document editing project in future which is going to need lot of pdf to word and vice versa conversions . What I did was I created a test word document converted into a pdf using a pdf maker in my word 2007 , Acrobat did convert the document from word to pdf keeping everything in the source file intact , However when i tried the other way round and attempted to convert the same pdf to word 2007 file format I lost my formatting ?So the font that I used to create the pdf are the ones taken from word 2007 which i believe is using the fonts that are installed in my computer. Any suggestions on how to preserve the formatting of the document after converting it from pdf to word file format?
Regards
Mike
