Digital Magnifier ================= The Digital Magnifier (digimag) program is a webcam viewing software designed to assist in reading text. Using a standard webcam and some type of stand and appropriate lighting, this program can be used to magnify, increase contrast, invert, and apply higher contrast colors to text being viewed. It also features an optional line across the view to help in focusing on a particular line of text. Usage ----- The options are controlled with simple key commands: d Next webcam device f Toggle fullscreen view (non-win32 only) i Invert the colors c Next color pair l Increment line size space Toggle line visibility esc Exit the program There's a default set of high-contrast color sets which can be overriden in the configuration file. Installation ------------ For systems where Autotools is supported, simply use: $ ./autogen.sh # if checked out from Git $ ./configure $ make $ make install # possibly as root depending on prefix For Windows, install Mingw and OpenCV and make sure their `bin` directories are the PATH environment variable. Then edit the first variable in `win32/makefile.win32` to point to the installation prefix for your OpenCV installation. After, change into the `win32` directory and run `mingw32-make -f makefile.win32`. If everything went properly there should be a `digimag.exe` file in that directory. Dependencies ------------ OpenCV 2.1 is used to grab frames from the webcam and process them. It can be optained from: http://opencv.willowgarage.com
