Applescript and OCR?

Hello,
Just a quick question. Is there a applescript or maybe better unix / ... scripting tool for OCR on pdf files. We have to archive a few millions documents. It's converting from pdf to OCR pdf files. But we need the fastest solution. We have several programs but would like to make it faster. Any suggestions or tips would be great!

I use it. Not too frequently, though.
can you give some advice?
Install libTIFF (BEFORE installing tesseract), then you will get support for multi-page TIFF's, and also support for compressed TIFF's
And remember to save in .TIF (and save as .tif, or just re-name from .tiff to .tif)
I heard about it here: http://hints.macworld.com/article.php?story=2010021805585497
You should be able to write an applescript to 1st convert your PDF to TIF and then process with tesseract (I also saw some python scripts to convert from PDF to TIF with google)

Need help with applescript and Xcode 4.3.2

I'm trying to write my first application that will involve a GUI. I can code applescript using script editor with a bit of effort, but I'm want to have users input more than one piece of information in the pop up. So, I download xcode, create my first applescript cocoa project go to MainMenu.xib and add a bunch of labels, text fields and buttons. Looks fairly nice... Go to start it and... nothing (well the window pops up, but it doesn't do anything). Unfortunately, I haven't figured out how to link the window to the applescript... So, how do I...
* Have the applescript prepopulate data in the text fields and pulldowns
* Once the user changes the data in the fields tell the applescript
* Tell the window to close and pass the control back to the applescript once either the cancel or submit button is pressed.
More detailed...
* What's an outlet and how do I use it here? Which of the 18 outlet(s) do i use for this?
* What's a property (referenced on one of the web pages I saw around applescript and cocoa) and do I need them here?
Looking at the documentation with xcode, there isn't a lot about xcode and applescipt. Looking at the web, the top links are a few years old. So, links to good relevent documentation would be very nice as well as direct answers to the questions
Thanks,
Scott

I'm not sure why you are closing it, but the NSApplication class is what keeps track of the windows. If you don't want to connect the window to an outlet from the interface editor, you can use something like
set theWindow to current application's NSApplication's sharedApplication's mainWindow()
...and from there you can use whatever NSWindow methods, for example
theWindow's performClose_(me)

Scanner and OCR don't Work in Acrobat 10.1.7

Up until yesterday, I was able to scan and OCR just fine. Today I realized that e-mailed pdf's did not OCR, instead, I got an "Unknown Error" on every non searchable pdf I was sent. I uninstalled and reinstalled, restarted, etc. and now, not only does the OCR not work, but now whenever I scan from my brother MFC scanner that worked fine yesterday, the scanning processing goes on forever with only black pages showing. For instance, a one page BW scan showed over 10 pages before I exited the process.
Also, e-mailing is much slower.
Interestingly, my Scansnap works fine for OCR (though I'm sure that isn't using Acrobat) and search of pre-OCR'd docs work fine. It's just frustrating that suddenly no docs e-mailed or faxed to me electronically can now be OCR'd.
I've tried printing to acrobat to no avail. I'd hate to have to print and re-scan just for OCR.

I'm scanning for malware now. The "slow email" was not described well, I meant that the "send" command in acrobat is particularly slow. My main issues are the sudden lack of OCR capability within Acrobat and the scanner issues.
I'll see what happens with the malware scan and in the meantime any help would me much appreciated.

Acrobat 9 OCR and "OCR Suspects"

I downloaded the trial for version 9.
Took a poorly scanned page and OCR'd it.
It (expectedly) had a few errors.
Then I selected "OCR Suspects" from menus.
What it should have done is found the "low confidence" results, but
instead, it said no OCR suspects were found.
This used to work in version 8, but I can't get 'OCR suspects' working in V9 trial.
Can anyone confirm if this works in the full version of Acrobat 9 Pro or Standard?

It's strange that while I posted to this Adobe forum, there is a response over at objectmix.com. As contributing to this topic from 2 locations seems confusing, I'll carry on here.
Amannagpal76 responded, saying in part that ClearScan in 9 Pro replaces Formatted Text & Graphics. Good to know this. ClearScan does, however, continue the mix. If ocr doesn't work on a character graphic, that graphic will continue to be displayed as such, amidst ClearScan's synthesized type 3 font imitation of the original font. This is most obvious when using the marquee zoom tool.
Aman suggests using the Touchup Text Tool and changing the font to any font installed on one's system. This doesn't work for ClearScan. Selecting a different font in Touchup for a PDF that came via a wordprocessor works fine, but not for a PDF that came via a scan. That, unfortunately, is the only time that ClearScan is used. The error message when I try this states that there's no system font to match the one in ClearScan, and text can't be added or deleted.
ClearScan is remarkable for the small size file it produces. That size can be reduced considerably even further by converting it to the Adobe 7 file format. ClearScan's synthesized font is also remarkable when enlarging the page on screen. Then you can see its true outlines -- rather chewed up in high magnification, but that's OK. It would be nice to extract the font in question and use it on one's system. One downside to ClearScan is that its ocr fails to retain italics when output to RTF and Word.
I have never found a suspect in 9 Pro.
The conclusion from the above is that the hidden text produced by any ocr'ing in 9 Pro can't be corrected.

Applescript and automator

I have studyed html for 3 days and wordpress for 3 days , word , excel for 5 days, and llustrator and photoshop 13 yeas ago for 6 months.
and still now its so hard to understand some how.
but I am in need of understading now with the printed documents from my computer.
and I wonder , so there are many defferent way to communicate with anyone out side of the world, right?
like I know email , fax, facetime,
but there are other way now I think because of the documents I found.
and also with applescript and automator can do anything possible like even the child can click one and start conecting etc..
I have the copy from its ,
does anyone have time to explain me what it is?
It's not that of teenager who doesn't want paretns to know or else,
but I am quite serious for my situations.
Please Help !

Using JavaScript to script System Events wouldn't be any better, since it uses the same Apple Events mechanism (how well it uses it is another topic). To hold down a key you would need to use something that has access to the deeper system APIs, most likely using Xcode.
And yes, your code snippet will press the arrow key 5 times (I am guessing that the missing space in key code is a typo). You can place the cursor in a bunch of text in another application such as TextEdit, and use your script to activate it before performing the key codes to get a better idea of what is happening (trying to reposition the cursor in the Script Editor will reveal a bug with the delay command).

Scanning and OCR

After scanning and OCR, when an attempt is made to seach the document, instead of locating the desired text, only a square box appears in the upper left corner of the document. Only after running OCR again from within the Adobe interface does the document become searchable. Any ideas are welcome.
Thank you.

Don't have the scan profile do OCR.
OCR after you have the scanner's output image in the PDF file.
Then OCR Searchable Image (Exact) is available as a choice when you initiate OCR.
Using Acrobat XI Pro you can build an Action that calls out the use of Searchable Image (Exact).
OCR a directory of PDFs that hold the scanner output images.
Close out the Action with a Save As.
Be well...

Scanned and OCR'd PDF--OCR content is not indexed

I am setting up a new SharePoint 2013 install, and have put a handful files in a doc library to test search. The content has been indexed, and I can find the content inside many files and file types without issue--including "native" PDF files.
However, it doesn't seem to index the content of a scanned and OCR'd (text with image overlay) PDF. I have verified that the text is indeed in the OCR text by copying and pasting phrases, and I also confirmed that the crawl log shows the file as successfully
crawled. The filename is also indexed.
So... it would seem that the SharePoint 2013 indexer does not index the text in scanned and OCR'd PDF files. Am I missing something? Can anyone else confirm this behavior?
Thanks!
Ryan

To clarify:
- From what I've read, iFilters can still be installed, but as Mikael said, they can't override the built-in file format handlers in 2013. 2013 has a built-in handler for PDFs, whereas previous versions required a PDF iFilter for indexing PDFs that have
text content. If one could install the Adobe PDF iFilter in 2013 successfully, it would resolve the issue in this thread, but PDF iFilters don't work in 2013.
- Aquaforest makes a product that OCRs PDF files. That takes an image-only PDF and makes the
file searchable, but it is not an indexer. Rather, it enables an index engine to make a big
collection of OCR'd PDF files searchable via a search engine.
- The built-in PDF handler in 2013 does index native PDFs. It does
not index OCR'd PDF files.
So, that's the issue for which I submitted the ticket to Microsoft. In our case, we don't need to OCR our PDF files--they are already OCR'd. But they don't show up in searches.
(Regarding Aquaforest... I've talked with someone there previously--for a non-SharePoint DMS--and they seem to make a cool product, but I don't have any personal experience using it.)

Is this possible in AppleScript and if so how ?

I am trying to make an app that opens AppleScript and types in things. I then want the AppleScript that the other Applescript wrote to save as an application, and rename it. Is this possible and if so, can you give me an example?

If I'm following what you want, the applescript editor is fully scriptable. In fact, there are a bunch of applescript samples in /Library/Scripts/Script Editor Scripts/ that show you how to use applescript to write and compile applescript code into a new window. Just for a quick-and-dumb example:
set the target_string to "X-X-X"
set the script_text to "display dialog \"" & target_string & "\" buttons {\"OK\"} default button 1" & return
set outputPath to POSIX path of (path to desktop folder from user domain) & "test.app"
tell application "AppleScript Editor"
          activate
          set newDoc to make new document
          tell newDoc
                    set its text to script_text
                    try
                              check syntax
                              compile
                    end try
                    save in outputPath as "com.apple.application"
          end tell
end tell

Using Applescript and Automator to manage files and folders

Hi all.
I need to make a simple action via applescript and-or automator to take the file it's been applied to (via the services) create a folder around it with the same name as the file.
So far, I've searched the web, found some solutions but none are really working.
Here's the script I found :
set myFolder to findFolder()
tell application "Finder" to set myFiles to files of myFolder as alias list
repeat with aFile in myFiles
set bName to my baseName(aFile)
tell application "Finder"
set folderExists to exists folder bName of myFolder
if not folderExists then make new folder at myFolder with properties {name:bName}
move aFile to folder bName of myFolder
end tell
end repeat
---------------- HANDLERS ----------------
on baseName(myFile)
tell application "System Events" to set {fileName, fileExt} to {name, name extension} of myFile
return text 1 thru ((get offset of "." & fileExt in fileName) - 1) of fileName
end baseName
on findFolder()
activate application "SystemUIServer"
-- Bug pointed out by Lauri Ranta http://www.openradar.me/9406282
tell application "Finder"
activate
set mySelection to (get selection)
if mySelection ≠ {} then
set mySelection to first item of (get selection)
if mySelection's class = folder then
set currentFolder to mySelection
else if mySelection's class = document file then
set currentFolder to parent of mySelection
else if mySelection's class = alias file then
set currentFolder to original item of mySelection
end if
else
set currentFolder to target of front Finder window
end if
end tell
return (currentFolder as alias)
end findFolder
And here's a page where they explain how to use automator and the Services to do what I <allmost> want, with some adaptation.
But it still doesn't work.
http://hbase.net/2011/08/17/move-selected-files-into-a-new-folder-using-applescr ipt-and-automator/
So if anybody has an idea n how I could do this ?
It It could either be a folder action (I drag and drop the files into a folder and boom, they get their folder around them)that I would set on a folder on a network drive, or locally, it doesn't matter, or a service (right clic on the file and boom folder around it.
So if anyone could help with this I'd be grateful...

Hi,
Make an Automator Service (Service receives selected "Files or Folders" in the "Finder.app").
Use this script in the "Run AppleScript" action:
on run {input, parameters}
    tell application "Finder"
        repeat with aFile in input
            if class of (item aFile) is not folder then
                set {tName, fileExt} to {name, name extension} of aFile
                if fileExt is not missing value and fileExt is not "" then
                    set tName to text 1 thru -((count fileExt) + 2) of tName
                    tell (get container of aFile)
                        if not (exists folder tName) then make new folder at it with properties {name:tName}
                        move aFile to folder tName
                    end tell
                end if
            end if
        end repeat
    end tell
end run
This script work on files with a name extension.

How can I remove asm and ocr installation in AIX?

Hi,
I try to install single instance with using ASM in AIX.
But I did not make successfully.
Now I want to remove ASM and OCR installation then
I will plan to make new clear installation.
How can I remove asm and ocr ??
Or How can I control my removing is fully correct ?

1) ASM Instance Clean-Up Procedures
Stop all of the databases that use the ASM instance that is running from the Oracle home that is on the node that you are deleting.
On the node that you are deleting, if this is the Oracle home which from which the ASM instance runs, then remove the ASM configuration by completing the following steps. Run the command srvctl stop asm -n node_name for all of the nodes on which this Oracle home exists. Run the command srvctl remove asm -n node for all nodes on which this Oracle home exists. If there are databases on this node that use ASM, then use DBCA Disk Group Management to create an ASM instance on one of the existing Oracle homes on the node, restart the databases if you stopped them.
If you are using a cluster file system for your ASM Oracle home, then ensure that your local node has the $ORACLE_BASE and $ORACLE_HOME environment variables set correctly. Run the following commands from a node other than the node that you are deleting, where node_number is the node number of the node that you are deleting:
rm -r $ORACLE_BASE/admin/+ASMnode_number
rm -f $ORACLE_HOME/dbs/*ASMnode_number
If you are not using a cluster file system for your ASM Oracle home, then run the rm or delete commands mentioned in the previous step on each node on which the Oracle home exists.
2) Deleting an Oracle Clusterware Home Using OUI in Silent Mode
!!! Oracle recommends that you back up your voting disk and OCR files after you complete the node deletion process.
If you ran the Oracle Interface Configuration Tool (OIFCFG) with the -global flag during the installation, then skip this step. Otherwise, from a node that is going to remain in your cluster, from the CRS_home/bin directory, run the following command where node2 is the name of the node that you are deleting:
./oifcfg delif –node node2
Obtain the remote port number, which you will use in the next step, using the following command from the CRS_home/opmn/conf directory:
cat ons.config
From CRS_home/bin on a node that is going to remain in the cluster, run the Oracle Notification Service Utility (RACGONS) as in the following example where remote_port is the ONS remote port number that you obtained in the previous step and node2 is the name of the node that you are deleting:
./racgons remove_config node2:remote_port
On the node to be deleted, run rootdelete.sh as the root user from the CRS_home/install directory. If you are deleting more than one node, then perform this step on all of the other nodes that you are deleting.
From any node that you are not deleting, run the following command from the CRS_home/install directory as the root user where node2,node2-number represents the node and the node number that you want to delete:
./rootdeletenode.sh node2,node2-number
If necessary, identify the node number using the following command on the node that you are deleting:
CRS_home/bin/olsnodes -n
Perform this step only if your are using a non-shared Oracle home. On the node or nodes to be deleted, run the following command from the CRS_home/oui/bin directory where node_to_be_deleted is the name of the node that you are deleting:
./runInstaller -updateNodeList ORACLE_HOME=CRS_home
"CLUSTER_NODES={node_to_be_deleted}"
CRS=TRUE -local
Deinstall the Oracle Clusterware home from the node that you are deleting using OUI as follows by running the following command from the Oracle_home/oui/bin directory, where CRS_home is the name defined for the Oracle Clusterware home:
./runInstaller -deinstall –silent "REMOVE_HOMES={CRS_home}"
Perform step 9 from the previous section about using OUI interactively under the heading "Deleting an Oracle Clusterware Home Using OUI in Interactive Mode".

IWeb Applescript and Automator - scripts you shouldn't be without

Applescript and automator will automate mundane manual repetative task that seem to take forever. These scripts fill in iWeb's void that makes it hard to implement advance features such one click ftp publishing, code editing, swithching domain site files, etc. Don't miss out on these scripts that will save you ton of time. These are scripts you shouldn't be without.

Thank you for your feedback.
-- Article never mentions compressed or uncompressed. Traditionally tiff format is used for buttons and small images on web pages and jpeg is used for higher quality photos exemplified by iWeb.
-- Search engine spiders or crawlers start from top of the page to the bottom of html pages. They craw for topic as well as content. This is exactly what appears from iWeb html pages for meta (meta name="Generator" content="iWeb 1.0.1")
-- I am the first to admit I don't know everything but I don't make up information. I use iWeb on a daily bases and try new things to push the envelope. Things that I find helpful to me I make it available for other iWeb community users so that they don't go through tribulation.
-- I put google ads and paypal donate buttons throughout the pages to test if iWeb is up for commercial challenge. I also tested how well the search and replace script worked. I have exemplified in macezzy website it is possible to use iWeb for business purpose. The script worked extremely well, it would have taken hours to insert google and paypal codes manually. Using the script it only took 10 min. I wanted to share that with other users who might wanted to do similar things. Sorry if that offend you, I will remove them.
-- I never claimed to have created the script except the script that makes the first folder in documents folder. I did change the wording so that it is clear to users that they are switching sites(domain file). I did not create the awesome search and replace script either. I do mention that I have made the iWeb_ftpUpload automator.
I have started macezzy site when iWeb was introduced and there wasn't much information about iWeb. I have and do try many things with iWeb and report to iWeb community users of things that I find helpful. I haven't made a dollar off the site and I have invested lot of my time because I like to see other users succeed.

Why logical partition is a must for voting disk and OCR

Hi Guys,
I just started handling jobs for RAC installation, I have a simple question regarding the setup.
Why does logical partition have to be used for voting disk and OCR?
I tried partition the disk that were provisioned for voting disk and OCR with primary partition but when OUI is trying to recognize the disk, it cannot find the disk that has been partitioned with primary partition.
Thank you,
Adhika

Hello Adhika,
I found it on this doc http://download.oracle.com/docs/cd/B28359_01/install.111/b28250/storage.htm
Be aware of the following restrictions for partitions:
* You cannot use primary partitions for storing Oracle Clusterware files while running the OUI to install Oracle Clusterware as described in Chapter 5, "Installing Oracle Clusterware". You must create logical drives inside extended partitions for the disks to be used by Oracle Clusterware files and Oracle ASM.
* With 32-bit Windows, you cannot create more than four primary disk partitions for each disk. One of the primary partitions can be an extend partition, which can then be subdivided into multiple logical partitions.
* You can assign mount points only to primary partitions and logical drives.
* You must create logical drives inside extended partitions for the disks to be used by Oracle Clusterware files and Oracle ASM.
* Oracle recommends that you limit the number of partitions you create on a single disk to prevent disk contention. Therefore, you may prefer to use extended partitions rather than primary partitions.
For these reasons, you might prefer to use extended partitions for storing Oracle software files and not primary partitions.
All the best,

Applescript and ditto

Hey all at the moment I am using this script to invoke the ditto command
I use this method because I can at least see the progress
but I would like something a bit better
like a display dialog at least that counts the amount of files and starts from 1 to what ever it is or some sort of percentage.
the bottom script does not open terminal and I would like to use the display dialog in the bottom script. is this possible.
I tried using 3rd party progress bars with no luck.
I am not very smart on coding. I only no a bit of applescript and unix.
Have been playing with xcode and interface builder but can never get the progress indicator to actually work for me.
set source to (choose folder with prompt "Select the Source folder")
set destination to (choose folder with prompt "Select the Destination folder")
set source_unix to quoted form of POSIX path of source
set destination_unix to quoted form of POSIX path of destination
tell application "Terminal"
activate
delay 2
do script ("ditto -V -rsrc " & (source_unix) & space & (destination_unix))
end tell
But.......
I rather use
set source to choose folder
set destination to choose folder
set source_unix to quoted form of POSIX path of source
set destination_unix to quoted form of POSIX path of destination
do shell script "ditto -V -rsrc " & source_unix & space & destination_unix
any help on this would be great
like I said I would like a loading bar but a display dialog giving me some indication on time -- percentage -- or file count would be great

the bottom script does not open terminal and I would like to use the display dialog in the bottom script. is this possible.
It can be done, but it takes a bit of extra work.
The issue is that when you invoke do shell script, AppleScript hands control over to the script and does not do anything else until that script returns control back to AppleScript. Therefore there's no way to display your progress dialog - AppleScript doesn't get a look-in until the script completes.
That's largely because in most cases you want your script to react to the results of the shell command and you can't do that if the command hasn't finished.
The exception to this rule is that you can tell the shell command to return control immediately to your script. This will let you run other AppleScript commands while the shell command executes in the background.
You do this by appending " > /dev/null 2>&1 &" to the end of the command. This redirects the output of the command to /dev/null and sends it to the background so that AppleScript can continue.
The trick now is in getting AppleScript to know the shell command's status.
For that the typical solution involves outputting the shell command's result to a temporary file (rather than /dev/null) which you can then read in via AppleScript. What you need now is knowing when the shell command is done which relies on another shell trick (hack?) that tells you the PID of the most recently launched command - you can use that to query if the process is still running.
So your command should end up like:
-- do your shell command:
do shell script "ditto -V -rsrc " & source_unix & space & destination_unix & " > /var/tmp/my.log 2>&1 & echo $!"
-- 'echo $!' allows you to capture the PID of that process
set thePID to the result
try
repeat
-- does the PID exist?
do shell script "ps -p" & thePID
-- so show progress
display dialog (do shell script "tail -1 /var/tmp/my.log") giving up after 2
end repeat
on error
-- we're done, so clean up
do shell script "rm /var/tmp/my.log
end try
The revised do shell script command writes ditto's output to /var/tmp/my.log and returns the PID of that process. The repeat loop then repeatedly checks that PID's status (via ps -p). If the process is running that command succeeds so the script progresses to the 'display dialog' command where it shows you the last line of the log file (you can change this to show anything you like).
If the ps -p command fails because the process is no longer running, that trips the on error clause in the try block which cleans up the temp file.

AppleScript and MIDI comms - is that possible?

I'm getting into AppleScript, had a lot of fun with FaceSpan - now I want to talk to my musical instruments over MIDI, how can I do that using AppleScript? It seems I need some "interface" between the AppleScript and the serial port. My latest idea is to somehow use OMS or even MIDI Manager but are these scriptable?
I have an idea that an "interface" might be possible that has been designed just to be scriptable, maybe this item already exists?? does it?
Basically this is the scheme:
AppleScript ->scriptable doofer -> serial port -> midi interface
the part I need to know about is the "scriptable doofer"
I'm using OS7-9 with OSX I believe MidiPipe would be the answer.

Voting disk and OCR disk in RAC

Can anyone explain me in basic terms ...
For what Voting and OCR disk are used in RAC.

Hi Francisco,
Thanks for the information.
But i am having lot of doubts in Voting disk and types of heart-beats present in Oracle 10g RAC.
As Oracle says css uses two heart beats 1. Network heart-beat 2. Disk heart-beat
My doubts:
1. How Oracle uses voting disk to avoid split-brain syndrome? OR what is the role of voting disk in split-brain syndrome?
2. How Oracle monitors remote node health?
3. Oracle says there is one more heart-beat where ckpt process keep on writing to control file for every 3 seconds and if it fails lmon process will evict the node....Is it true?
5. Oracle Clusterware will send messages (via a special ping operation) to all nodes configured in the cluster, often called the "heartbeat." If the heartbeat fails for any of the nodes, it checks with the Oracle Clusterware configuration files (Voting disk) to distinguish between a real node failure and a network failure......Is it true? If true then what about the two heart beats(Network and Disk)...why these heart-beats are present or useful?
If possible please clear my doubts by giving some simple examples....
Awaiting for your reply and too much eager to learn and expertise in Oracle RAC architecture before administering it.

Yasser.
