How can detect and remove scanned white pages in an OCRd pdf file?

Acrobat does not support an automated way of doing this directly. You can
remove completely blank pages (pages that don't have any "marking
objects"), but a scanned page does contain an image, so Acrobat won't help
you here. There are a number of 3rd party applications and plug-ins
available. Try a Google search for
remove blank pages from scanned
pdf<http://www.google.com/search?client=safari&rls=en&q=removeblankpagesfromscanned+pdf&ie=UTF-8&oe=UTF-8>
This will bring up a few different solutions.
Another way is to use JavaScript to find text. You say that these documents
are OCRed, so if you have a blank page, it should not have any text on it.
With some JavaScript, you can identify pages that don't contain text. This
may however fail if you have a page that contains just e.g. a photographic
image. There won't be any text, but the page is certainly not blank.

  • How can I set the maximum number of restarts for my PDF files?

    I want sent my PDF to a friend,but I just allow him see it only twice.
    How can I set the maximum number of restarts for my PDF files?
    My software edition is Acrobat X

    In the old days when PDFs were only opened on desktops and only in Acrobat or Reader, scripting could fake security features and people were generally convinced. As there are so many ways to open a PDF without scripts ever being run (from mobile devices to in-browser display, or simply opening the file in Illustrator), none of that works anymore.

  • Adobe_flashplayer_e2c7b_Setup.dmg Is this malware? If so, how to detect and remove it?

    adobe_flashplayer_e2c7b_Setup.dmg 
    Is this malware? If so, what is the easiest way to detect and remove it?

    There is no need to download anything to solve this problem.
    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • Iphone hacked?  Please help on how to detect and remove  possible malicious software/apps

    Hi,
    I have an iphone 4s.  I've installed iOS 7.   Some one has been harrasing me and seems to have access to my info on the phone.  I use icloud and the phone apps for calendar and they seem to know detail that are only in my calendar on my phone.
    I have changed the password for icloud from a safe computer many times and have re-installed the OS on the phone  and have gone through all the apps and removed any that I don't absolutely trust.
    Is there any way to see if there is an app on the phone that enables hacking/sharing of the info. on that phone? 
    Any advice on what to do?  It's not that information about my calendar is all that important but it just creepy that someone would be so evil to do so and it creeps me out-I want to make sure my phone is private and only I have access to my own information.
    Any help and advice is much appreciated.
    Thanks.

    Unless your iPhone has been jailbroken it cannot be hacked.
    The person is obtaining the information form somewhere else.
    Do they have access to your email account like Google? or Hotmail?  If your Calendar is linked to those and they have access they would be able to see your calendar.
    As was suggested above, change your Email account passwords.

  • How can I replace just the corrupt page(s) in the domain file of iWeb using Time Machine?

    I back up with Time Machine and have an extensive elaborate website I created in iWeb '09 over a couple months and publish to a local folder and then upload to my server, but in the last few days I notice certain pages (that I haven't even worked on or touched) somehow become corrupted or "cross-contaminated" with elements and images from other pages.  Once I see they are corrupt I make sure not to publish them (if the current published versions are the correct, non-corrupt versions) or if they did get published I can use Time Machine to retrieve the .html file and page files folder for that specific page and replace it in my published folder/server so it shows correctly on the Web.  However, that does not replace the corrupted page(s) you see and work with when you launch iWeb and try to edit or continue working on that page.
    I am confused as to how I go to the package contents of the domain file and replace just that page with a previous version from time machine.  I don't want to replace the entire domain file because I have new changes I made to other pages even in the past hours.  How can I keep the good pages and just get earlier, non-corrupted versions of the corrupt page(s)? I know it's not as easy as with the published site folder where you can just replace the page's .html file and folder, but I don't want to have to re-create the corrupted page(s) from scratch or have to replace it with the last non-corrupted domain file and then have to redo all my recent changes to new pages I made before discovering the corrupt page(s).  Thanks for your help as now I can't make changes to the page(s) within iWeb itself.

    Thanks for the response, Wyodor.  I don't know what that is, but I'll have a look.  Is it an alternative to iWeb or a way to transfer pre-existing iWeb sites?  When you say merge domain files, is that like so multiple copies of the same site show up then you can pick and choose the non-corrupted pages and group them then delete the corrupted ones?  I am on Snow Leopard with no plans or need to upgrade anytime soon.
    And yes, I will read your links but just wanted to ask those questions.  Maybe they'll answer my questions, maybe not.
    I was able to discern that within the domain file is a domain folder with all the site folders, each with their own page ".gz" files which expand into ".xml" files.  I was trying to figure out if you could simply drag the corrupt pages out that way and replace them with backup copies that are still good.  I am having trouble discerning which pages are which as they all have random names like site-page-30F175E3-AE33-4F10-A490-1A096D9B185B.xml and although I expanded and opened each in Text Wrangler, I still couldn't discern which were which for sure, and trial and error proved cumbersome.  Also, I did notice some of the later corrupted domain files had one or two more pages than the site itself has, so not sure how they got added or duplicated or what.
    Again, I'll look at your links, but do you know about swapping out individual page .xml files this way within the domain file?

  • How can I get Safari 5.1.2 to automatically open pdf files on web pages by using Adobe Reader?

    Safari 5.1.2 always opens pdf files on web pages as a single frame and thus it will not print properly.  How can I get Safari to open all pdfs with Adobe Reader 10.1.1?

    Carolyn,
    Thanks for sending your suggestion on how to solve my problem.  Unfortunately, it did not work for me.  I trashed the file, quit and relaunched Safari, but the problem remained the same.  Although it did not work, I do appreciate that you took the time to try to help me.
    Thanks.

  • How can you set (or reset) different page sizes within 1 pdf?

    I am working on a pdf with various page sizes.  Say one page at 8-1/2 x 11, another at 11 x 17, and another at 22 x 34.  I obviously can't print as "Choose paper source by PDF page size" as one printer can't do all sizes.  I would like to change the 22 x 34 to 11 x 17.  How can I change the page size setting of one page within a multiple-paged pdf?

    You can play with the Crop tool. You'll find it is easier to "size up" than "size down".
    May have to extract and bin PDF pages by the virtual page size then work on them.
    However, if all you want is to have the content on hard copy and having that on a common sheet size (say Letter) then consider this alternative:
    Make a working copy of the PDF.
    With the PDF open in Acrobat, open the Pages panel. Expand the panel width as desired.
    Now, Ctrl click through the PDF page thumbnails that have a landscape orientation.
    Rotate these 90 degrees to a portrait orientation.
    Alt+D+T or Shift+Ctrl+R
    Save as you go.
    With all pages in a portrait orientation, use the attached printer to print.
    In the Print dialog locate the entry for 'page scaling' and select Fit or Shrink to Printable Area.
    All PDF pages' content will be scaled such that all page content fits in an imprint on the Letter size paper.
    Or, go the other way and have the imprint of PDF page content fill a larger sheet size.
    Just a function of what the printer accepts for paper size and the features provided in the printer driver.
    Be well....

  • How can I print an article from the web to a PDF file?

  • I need to make a pdf document, made in photoshop, 'page turn' and then add it to my website. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

    I need to make a pdf document, already made in photoshop, 'page turn' and then add it to my website as an e-brochure. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

    Hello waitingone,
    please try this (all terms are translated from my German programs to my best knowledge):
    1. Did the creator of the pdf file enable the import options?
    2. See import options: choose an other visibility option for your layer.
    3. Let you show the import options and click into one with a black background and try these out (often a gray is selected).
    4. See trimming: try the different modes there. Often works: "Media".
    5. Is the pdf file (eg from Word) correctly created?
    6. Is the PDF file protected? >>> no import possible.
    7. If that does not help, store the pdf file in Acrobat, repair possible errors, run the PDF Optimizer before placing in InDesign.
    Good luck!
    Hans-Günter

  • Hi, I would like to know how can I recover a document from pages that I didn't save anytime and instead of clicking the button save I clicked the delete button at the end. Is there any way to recover it?

    Hi, I would like to know how can I recover a document from pages that I didn't save anytime and instead of saving the doc I clicked the delete button. Is there any way to recover it?

    Regardless of application, the first step that I take is to save and name the current document — even if it has no content yet. With Pages, this good habit enables autosave. As you add content, your document revision history is restorable via the File Revert To menu. The delete key has the same document foreboding as only teaching a pet raven to speak "Nevermore."

  • How can I completely remove iTunes and all associated files/programs from my Windows PC?

    How can I completely remove iTunes and all associated files/programs from my Windows PC?

    iTunes, along with Quick Time, iCloud, Apple Software Update, Bonjour, Apple Mobile Device Support and Apple Application Support can all be removed from your PC by uninstalling them using 'Uninstall or change a program' in Control Panel. The only obvious thing that will be left behind is your iTunes library which remains untouched. If you want to remove that as well it's just a question of deleting it.
    Hope that helps.

  • HT4007 I have just transferred all my raw, jpeg & tiff files into LR4 and using to opportunity to delete old raw files to free up disc space. How can i completely remove a raw file from my msc disc??

    I have just transferred all my raw, jpeg & tiff files into LR4 and using the  opportunity to delete old raw files to free up disc space. How can i completely remove a raw file from my mac disc??

    I'd be careful here: LR references files. It can copy them, like from an SD card to your hard drive, but it doesn't necessarily make duplicates. So when you say you "transferred" those files "into" LR it just means you referenced existing files. And if you delete those they're gone, unless you've made copies. LR does not import files by copying them into a managed library like Aperture does.

  • How can detect that cdrom drive were opened and closed?

    How can detect that cdrom drive were opened and closed?

    I'm sure there are more elegant and complicated ways to accomplish this using Windows SDK function calls to kernel32.dll or something extravagant like that, but if you want the bare-bones easy way to check if the CD-ROM tray is currently opened, then simply use System Exec to query the CD-ROM drive from the command line. One example of this is shown below.
    Use the command line function cmd /c d:, where d: is your CD-ROM drive. If the Standard Error output from System Exec.vi is "The device is not ready." followed by a carraige return and line feed, then voila, your CD-ROM drive is open. If not, it's closed. Anyone have a better idea? I'm sure one exists...
