On the Location’s Pipeline settings tab, uncheck Use Default Pipeline Configuration.nothing you can select, copy and paste on your PC). Define a location that contains PDFs and/or images with human-readable but not machine-readable text (e.g.Copy the script \Scripts\ocr_last_step.py to your \app\py\pipeline\steps\ folder.From either the command-line or PyScripter (for example), text extracted from the images will be printed to the console.Independent of a Voyager install, you can test that components are in place and working as expected by running the script test_ocr_last_step.py against each of the ocrtest.pdf and ~.png file (contact Voyager Support and Professional Services for information about this file and the Python step.) OCR with PDFs writes its work in progress to this directory.īy following the steps above, all of the software prerequisites should now be installed. Make sure the directory c:\temp\ exists.Install PyPDF2 with pip … > \Scripts\pip.exe install pypdf2.Install PythonMagick by running the command > pip install PythonMagick-0.9.10-cp27-none-win32.whl.If PIP is not installed (it is not installed by default in Python 2.7.8), you can install PIP by downloading get-pip.py from here and running the command > python get-pip.py. The easiest way to install Python Magick is by using a WHL (wheel) file using “PIP”.PythonMagick (Python Bindings for ImageMagick) All versions of the Visual C++ Redistributable packages can be downloaded from Microsoft’s website.Ensure that the list of installed programs contains the following: NOTE: Some issues were encountered on minimal builds of Windows Server 2012 R2 that did not include legacy (pre 2013) 32-bit (x86) Visual C++ Redistributable packages.Set the MAGICK_HOME System environment variable to the full path of this folder.Download the ImageMagick installers from here.Double-click the executable to run the installer all installation defaults are acceptable.Add the full path to this folder to your PYTHONPATH.Unpack the contents of this file to a folder called ~pytesser_v0.0.1~ and copy this folder to \Lib\site-packages.Download the PyTesser libraries from here.PyTesser (Python Bindings for Tesseract OCR) On some machines (Windows Server 2012 R2), you will need to add the tesseract install folder to your Path System Variable and create a TESSDATA_PREFIX System Variable set to the location of your Tesseract-OCR install.Download the Tesseract OCR libraries from here.Double-click the executable to install into the Python 2.7 location (above) all installation defaults are acceptable.Python Image Library (PIL) 1.1.7 for Windows Python 2.7 32-bit We recommend that you include your 32-bit python path on your System PATH environment variable, and that you also set this as the (initial) value for your System PYTHONPATH environment variable, as follows:. ![]() To confirm your version and architecture, simply run python from your command prompt.Under the assumption that Voyager is co-installed with ArcGIS Desktop, these scripts have been designed to work with this version of Python. Python 2.7.8 should have been installed with ArcGIS Desktop (10.3.1 or earlier). The specific versions of the specific builds must be installed per these instructions for PDF and image OCR to work as expected. The following modules and external components are used to run this script. This article describes how to implement a script that runs OCR during the last step of the Indexing Pipeline. Voyager's OCR functionality processes image-based text in index records from PDF, TIF, PNG, BMP, JPG and GIF files. Optical Character Recognition (OCR) is a method of converting images of text into a character-based format that can be used in computer-based processing and analysis. Optical Character Recognition ( OCR) is a method of converting printed text into digital format so that it can be used in computer-based processing and analysis. Over 90 image formats are supported, including GIF, JPEG, JPEG 2000, PNG, PDF, PhotoCD and TIFF.Configuring Optical Character Recognition (OCR) Image processing operations are available from the command line as well as through C, Ch, C++, Java, Perl, PHP, Python, Ruby and Tcl/Tk programming interfaces. You can crop, resize, rotate, sharpen, color reduce or add effects or text or straight or curved lines to an image or image sequence and save your completed work in the same or differing image format. ImageMagick is a robust collection of tools and libraries to create, edit and compose bitmap images in a wide variety of formats. Tools and libraries to manipulate images in many formats ![]()
