#Ocr for mac maven pdfIf you insert an image or PDF containing text, the app sends that image to Microsoft servers to perform the OCR process. Interesting point and your characterisation of myth of feature-equality in Office apps is spot on and this is one example. On the Mac, when one opens a tooltip (lets say the tooltip says “BigHelp.” When you open it, you’re likely to find nothing but a reprise of the word “BigHelp.” #Ocr for mac maven how toIn Windows, once one finds a tooltip by hovering over an icon in the toolbar, opening that tooltip often reveals detailed instructions on how to accomplish what the tooltip describes. All one needs to do to realize that’s not the case is to open a create an Excel worksheet in Windows, enter some data, then turn to the tooltip help for suggestions on how to manipulate or format it. My sense is that Microsoft spends a lot of time trying to sell Mac users on the untrue notion that the Windows and Mac versions of Office are now feature-set equals. #Ocr for mac maven for macAnd, I suspect, there’s no way then to prevent altering the OCR layer to change the formatting or even the meaning of the scanned document.įinally, since I don’t use OneNote (I’m still in the Evernote camp), but I’m uncertain what you meant to say when you wrote “there’s a huge queue (days) to process images in images…”Īre you saying that the obstacle for Mac users is that they must wait a long time, or that the capability just doesn’t exist in Office 365 Mac. I don’t think there’s a way to prevent OCR of a pdf that is locked for editing but obtained elecronically, then printed. #Ocr for mac maven fullThere’s a reason that full Adobe Acrobat DC is so expensive (OK, much of it possibly is greed), but it does include features that attempt to make certain that it’s not only portable, but also permanent. Sorry to venture so far afield, but in some ways the PDF file format is a real mess, and many people, I think, place far too much credence on the notion that if it’s a PDF, it’s the same as was intended by its author, and that’s under intentional and unwitting attack, as well as being limited by the tools (such as what character set is embedded in the original) used to create it. (For example, look at the piece from last Sunday’s 60 Minutes broadcast, discussing the recent discovery that many of the printed copies of Columbus’s letters to King Ferdinand in famous museums, including the Vatican’s, describing his first voyage to the New World are actually very recent forgeries, and that one of the stolen documents was discovered in the US Library of Congress. #Ocr for mac maven softwarePDFs as created may be locked for editing and password protected for access-at least when transmitted electronically-I have no idea how one can block editing access to a piece of paper once one has it in one’s possession, at least if one has the right software tools). If one creates (or copies) a PDF by scanning a paper document, the creator of the document may be very unhappy to learn that it’s been altered. ![]() I’m pretty certain it was conceived as a way of distributing printable documents that would look the same on screen or in print, and that capability was one of the things that made the PostScript Laser Printer such a success in the 1980s. ![]() However, there is of course a huge difference between searchable and editable, and that brings up the very intention of the nature of the PDF document format. Last but not least, kudos to the Apache Software Foundation for their continuing work towards great Open Source solutions.As Adam mentioned, there are many ways to create searchable text by OCR in scanned documents e.g., the scanning/OCR software available with Evernote for Mac. If you want to see the full code for this example, you can check it out on GitHub. Tesseract OCR is a pretty tricky field in and off itself, so be sure to check out all the tweaks you may have to make for your particular dataset. ![]() Pretty easy, right? Check out the Apache Tika documentation to see what other great functionality is available. Some, like JPEG2000, might require extra supporting software to be installed on the machine.) (The example file is a jpeg, but lots of different image formats, as well as PDF, are supported. If the result is a Success, I convert it into a regular String, which can then be printed, or otherwise used at your convenience. Because using InputStreams and doing parsing are two IO processes that can (definitely) throw Exceptions, I have delegated the handling of the InputStream using Scala’s Using functionality, which will automatically wrap the whole operation into a Try while also making sure that the InputStream is closed when everything is done, even when exceptions are thrown. We just turn the file we want to OCR into an InputStream and hand that off to the TikaOCRParser we specified above for parsing. ![]()
