Using InftyReader: A Getting Started for Screen Reader Users

InftyReader is a GUI application. It can be used in command mode in the Console Window by running Infty.exe from the Infty program folder. This tutorial is restricted to the GUI version. Command mode use is covered in the InftyHelpE.txt file included in the archive.

Step 1:

Start InftyReader. You will find a number of buttons and edit boxes if you TAB around the initial InftyReader screen. Use space bar to press buttons, not Enter. The screen has the following elements:

  • Three buttons giving you the choice of selecting a file to recognize, a folder to recognize, or to scan in a document.
  • A read-only box that will show the current input file/folder name. It is initially empty.
  • A radio selection box permitting you to select the desired input format. Choices are Tiff, BMP, GIF, PNG, and PDF.
  • A read-only box showing the output file/folder name. It is initially empty.
  • A radio selection box giving you the choice of output format. Choices are IML, LaTeX, HR-TeX, XHTML(MathML), and Microsoft Word 2007 (XML).
  • A yes/no choice of whether to open the output file in the appropriate application. Default is “no”.
  • Choice of whether to put a NewLine indicator at the end of each paragraph. Default is to do so.
  • The “Start OCR” button that should be pressed once all selections are made.
  • An Exit button that closes InftyReader
  • A choice of math level as “all math symbols” or “High school math symbols”. Select the latter if the math is simple, because recognition will be better.
  • A choice of using InftyReader in English or Japanese.

Step 2:

Set the various options and then click on the choice of file, folder, or scan input.

  • If you choose to convert a single file, click the “file” button by pressing space bar or left-clicking the mouse. This opens a standard Windows “open” dialog that permits you to type in the file name or browse for it. There is a choice of keeping this file as “read-only”, and an “open” button. After selecting the file, press the “open” button. After a short processing delay, the initial screen re-appears with the input and default output file names filled in. You may edit the output file name or browse to another folder if you wish.
  • If you click on “folder”, you open a selection tree that permits you to browse for the desired input folder. Once the folder is found, press “ok”. The initial screen re-appears with the input folder name filled in. The Output file name box is empty. You cannot edit the output folder name. An additional box appears, giving you the choice of whether to convert files in sub-folders. Default for this “Search sub-folders” choice is off.

Step 3:

Set the desired dpi level in the box giving an option of 600 or 400 dpi. Then press the “Start OCR” button with space bar or mouse.

  • If you have selected LaTeX for the output format, after pressing the “Start OCR” button, you will be given a long list of LaTeX options. If you are LaTeX-savvy, you will recognize these options. If not, we recommend that you choose your desired paper size and then accept all other default options and press “ok” to continue.
  • If you have chosen to convert a single file:
    • The output file will be in the same folder as the input file and, by default, will have the same name except for extension. The extension will be whatever was selected for output format. For example, File0.tiff will produce output file File0.iml if iml is the output format, File0.tex if LaTeX is the output format, etc.
    • You will find that there are other files produced by InftyReader as well, in the same folder as the input and output files. At a minimum there will be a log file, sometimes several log files. Other files will be produced, depending on which output format is used.
  • If you have chosen to convert a folder:
    • InftyReader will convert all image files in that folder having the specified input format. All output will be put into a single file having the name of the folder with extension of the output. For example all files in the folder Hi will be in the single file Hi.iml for iml output, Hi.tex for LaTeX output, etc.
    • If the “Search sub-folders” box is checked, InftyReader will convert files in all sub-folders as well. All output in sub-folder HiThere will be in HiThere and gathered together into the single file HiThere.iml, etc.
