How to compress pdf with images

How can we compress pdf size using Acrobat SDK?

Waiting for your important ideas.
Thanks & Redards,

Hello, lrosenth:
I want compress pdf with c#.
More details:
1.      Use in ASP.NET web site
2.      pdf files user uploaded with big image
3.      Compress pdf size using Acrobat SDK
As you said “When you do the PDDocSave, be sure to specify all the various compression options including full save.”
Could you tell you how to set the options with C# by program?
Waiting for your important ideas.
Thanks & Redards,

  • Problem in creating client side PDF with image using flex and AlivePD

    I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
    Thanks in advance
    Atishay

    I am having a similar and more serious problem. It takes a
    long time to execute, but even attaching a small image balloons the
    pdf to 6MB plus. After a few images it gets up to 20MB. These are
    100k jpeg files being attached. The resulting PDF is too large to
    email or process effectively. Does anyone know how to reduce
    size/processing?

  • Compress PDF with Leopard

    I just upgraded to Leopard and miss one thing a lot from Tiger.
    For work, I used to compress PDFs with Tiger to send them by mail and now, that option has been removed from Leopard.... It's just impossible for me to send PDFs as big as 10mo by mail. Does anybody has any idea about how I could compress them ?
    Thanks everyone

    Hey there
    If you don't have access to the original Tiger workflow, then just create a new workflow in Automator: Open automator, go to the pdf section, look for the reduce file size or compress pdf workflow, go to the finder section, add a copy or move to action that moves the file to the desktop and that's it. Then save the item as a workflow in /Library/PDFServices
    BTW - you can also use this process to create workflows to do absolutely ANYTHING you want and put them in pdf services.
    I think Apple removed the original workflow in tiger simply because it wasn't necessarily suited to everyone, and it's so easy to add in workflows that are customized yourself into pdfservices.
    Hope that helps.

  • How to use recursion with images

    Ok, for this program I'm trying to recursively repeat an image 3 times with varying widths and heights, and I don't know how to do that with images. With rectangles and other shape objects it's easy because all I had to do was override the draw method, but with images I'm not sure what to override to allow me to repeat the drawing of it with a different height and width. Any help would be greatly appreciated.

    Would I be able to work that in with recursion? Currently I have a JPanel with the paintComponent method being overridden, and I've tried setting up the paintComponent method to call itself to repaint the image, but I've realized everytime I resize the application's window paintComponent gets called again making the images go out of site. Is there a way to override the drawImage method to allow me to change the width and height of the image without causing the panel to repaint itself?

  • How to examine pdf for image file formats, OCR, and layers

    Hi,
    I have a question about how to find out specific features of a pdf.  I am using Adobe Acrobat 9 Pro for windows.
    With any given PDF, I am looking to find out:
    a]  The specs of any image files used  to create the pdf (i.e., if the pdf is made up of text pages with image objects on top of them, are those image objects JPGs?  TIFFS?  What resolution are they? Are they compressed?)
    b]  Does this PDF have OCR already embedded in it?
    c]  Does this PDF have multiple layers?
    with a] -- file format is perhaps the most important, resolution and compression being second most
    with c] -- is there an easy way to see the layers, visually, on the page images?
    What is a smiple way to find out this information?
    I've poked around a bit in the "Examine Document" function, and various checks in "Preflight," as well as the help manual, and have found bits and pieces that look like some of what I'm looking for, but nothing simple or conclusive yet.
    Any help or advice would be wonderful!  I just want a simple way to be able to see what my PDF is made out of, in terms of image files, OCR, and layers.
    Thanks,
    Andrew

    Preflight is inded the best way to do this operation. You may have to read a bit to figure out what you are looking at, but that is the right route to take.

    Never, never use Photoshop as a PDF editor unless you know that it is a PDF with raster images at know resolution (including the case where you made it with Photoshop first time around).

  • How to install PDF with XDB on APEX 4.2.2

    Hi,
    does anyone know a "how to install PDF Output" using XDB instead of Apache or APEX Listener on APEX 4.2.2 Please give me the link.
    I tried to install APEX Listener but I always got errors so I came back to XDB. If there is an easy way to install the Listener please send me the link.
    Thank you and best regards
    Siegwin

    i wrote an article about installing listener but then the latest version of listener at time was 1.x . check the following
    Vishal's blog: Installing SSL enabled APEX 4.1 with development environment and APEX Listener on Weblogic and standalone
    listener now is at 2.x and a few steps such as configuration of properties have changed. you no longer have to create users such as adminlistener and the listenerAdmin page isnt there anymore.
    read the above and tell me the exact problem you have and i might help you better.
    read Contents . this is oracle's documentation for listener configuration. this is good. let me know if you need some help in understanding some step in this
    once listener is configured, configuring it for pdf download is very easy.
    let me know if this answers your query in the current thread

  • How to sign  PDF with a smart card or USB token in C# through IAC ?

    Hi,
    My goal is to apply a certification signature (MDP) to a PDF document with a smart card (Belgium identity card) from a C# application.
    I start Acrobat through IAC.
    The JavaScript object apparently can only sign with PKCS12 file (.pfx)...
    To sign a PDF with a smart card I need to develop a plug-in if I am right?
    The samples in the SDK are to get a certificate from the windows certificate store or to write a Third party handler.
    I already get the certificate context (an HCRYPPROV object from windows certificate store)
    How can I create a signature field but mostly sign it? With DigSig I guess, but I’m lost in the API… does
    I have to use DigSigSignDoc ?
    Syntax : void DigSigSignDoc(PDDoc pdDoc, CosObj sigField, ASAtom filterKey)
    The filterKey value for the windows certificate store is “Adobe.PPKMS” but how can I choose my certificate?
    I also have to build a signature reference dictionary i guess?
    What does i have to do and in which order? I can't find any documentation on this.
    There is a more simple way?
    Thank you,
    Goffin
    Fabian

    Hi,
    -download the JDK sample "sdkAddSignature.js"
    -change the sign methode like this :
    Sign = app.trustedFunction (
        function( sigField, DigSigHandlerName )
       try {
       app.beginPriv();
       //the diSigHandler is "Adobe.PPKLite"
       var myEngine = security.getHandler(DigSigHandlerName);
       var ids = myEngine.digitalIDs;
       //choose an id which is installed in the microsoft store
      var oCert = ids.certs[3];
      // for (var i=0; i<ids.certs.length; i++)
      //  console.println("certificat n°"+ i + " " +ids.certs[i]);
      var oParams = {cPassword:"0000" , oEndUserSignCert:oCert }
      if(myEngine.login({cPassword:"0000",oParams:oParams,bUI:false}))
       console.println("OK");
      else
       console.println("Error");
      console.println("sigfield :" + sigField);
    sigField.signatureSign({oSig: myEngine,oInfo: { password: "0000",reason: ACROSDK.sigReason,location: ACROSDK.sigLocation,contactInfo: ACROSDK.sigContactInfo}}); 
    app.endPriv
       } catch (e) {
       console.println("An error occurred: " + e);
    -perform some test using the javascript debugger
    -and finally use IAC to execute the script

  • How to load folder with images php with oracle

    $lob = oci_new_descriptor($conn, OCI_D_LOB);
    $stmt = oci_parse($conn, 'INSERT INTO FOTKI (FOTKAID, FOTKA) '

    // The function $lob->savefile(...) reads from the uploaded file.
    // If the data was already in a PHP variable $myv, the
    // $lob->save($myv) function could be used instead.
    if ($lob->savefile($_FILES['lob_upload']['tmp_name'])) {
    oci_commit($conn);
    echo '<p>Obrazek załadowano</p>';
    else {
    echo "Couldn't upload Blob\n";
    $lob->free();
    oci_free_statement($stmt);
    oci_close($conn); // log off
    ?>

    The first thing I'd suggest you fix is the forum to which you posted the question.
    The name of this forum is "Oracle Database General Questions." That is questions about the database ... not questions about PHP.
    Look further and you will find the correct forum.

  • How to populate ComboBox with images?

    Hello, I was just wondering if it is possible to populate a
    ComboBox with images or icons? If it is possible, I want each item
    to have both a picture and text. Any help on this matter would be
    great!

    I'm using Flash AS3. I currently have the code working for
    the tileList component. I load the "label:", "source:" and "data:"
    from a php script. It works great! Tried to do the same method for
    the comboBox with no luck. I have spent lots of time searching the
    web for help on this, but unfortunately AS3 is still relatively new
    and much differant from previous versions of actionscript, so it is
    hard to find any good examples. Although the help and examples for
    AS3 is pretty extensive on adobes website, it seems that I can
    never find the help and examples that relate to any problems I
    might encounter.
