This is a appears to be a difficult problem because there appears to be no straightforward way to remove renderable text. If you try to open the PDF in Preview and print as PDF or even as PostScript, the renderable text still remains.
The solution lies in exporting the PDF to an image format, e.g., TIFF. TIFF is better than JPEG because you don’t get rendering artifacts. Also it supports multi-page documents. PNG does not give artifacts, but also does not allow for multi-page documents.
When exporting to TIFF make sure you select a high DPI, e.g., 600, to preserve quality. The default is only 150 which is too low.
Then open the such created TIFF once more in Preview and re-export as PDF.
The such created PDF should pose no more problems for OCR in Acrobat.
With all the recent scare about Java on Mac OS X I spend a lot of time looking for good guides of how to disable or uninstall it. Unfortunately, good information is hard to find.
Have you had difficulty installing Acrobat 11 on Mac OS X Mountain Lion 10.8.2? I did too. And of course the solution is easy if you know how.
In windows XP this was easy, in Windows 7, apparently one needs to edit the registry as suggested here:
Let XYZ be the extension you want to deassociate.
With a registry editor (e.g., regedit.exe),
1. go to
remove the subtree .XYZ
2. go to
remove the subtree .XYZ
remove the subtree XYZ_auto_file
When I tried this, step 1 seems to suffice. Why it has to be so complicated is beyond my understanding.
So you worked tirelessly and updated your custom dictionary on MS-Windows with all your specific technical terms of your area of work and then you get a new computer or a new hard drive and all is gone. How to avoid this? Simply copy the file “Custom.dic” from your old installation to the new one. Where is it? Here: “UsersUSERNAMEAppDataRoamingMicrosoftUProof”; simply replace “USERNAME” with your login ID.
One of the annoying aspects of working on a new computer is that Outlook does not know your past recipients. Name completion in e-mails only works for previous recipients. There is a simple solution. Copy the Outlook settings file from your old default installation to the new one. But where is it? On Windows 7, the file is called “MS Exchange Settings.NK2″ and can be found here: “C:UsersUSERNAMEAppDataRoamingMicrosoftOutlook”; simply replace “USERNAME” with your login ID.
Bento 4 comes with a nice set of templates. It is also easy to customize these templates; however, once customized, there is no straightforward way to duplicate a database. For instance in my case I customized the “Vehicle Maintenance” Template by replacing the ‘Location’ field with a drop down menu populated by various places I go for my car service. I did not want to set this up from scratch for another vehicle. Continue reading
How many times have I wondered if there are any stores that don’t say “xx items or less”
