Using Dyslexic Fonts To View PDF and TTF Docs

I am a dyslexic,  I thought I would write up some information that might be helpful to others.

There has been a great deal of comment in recent days on social media about dyslexic fonts such as OpenDyslexic and Dyslexie Font.  Thinking about these fonts I realised that you could potentially use special software to convert difficult to read documents into something far more readable for a dylexic.  You can use free optical character recognition software (OCR software) to convert read only documents such as those in PDF or TTF format into editable documents that you can then change the font on.  If you selected the dylexic font you will have converted your tricky document into something more readable.

The software you will need will vary depending on what sort of computer you have.  I have a Windows 7 64bit PC but your could be different so when you following these instructions you will need to look out for what sort of software you need to suit your own particular computer.  If you have trouble doing this or following these instructions please contact your local computer support person and pay them to help you – Do not email me – thanks 🙂

Instructions:
– The OpenDyslexic font can be found at http://www.dafont.com/open-dyslexic.font  and clicking download.

– After you downloaded the dylexic font you will find that it a zip file.  This can be extracted using free software such as 7zip.  You can get 7zip from http://www.7-zip.org/download.html.  To install the fonts on my computer I just copy them to C:\Windows\Fonts.

– There is variety of free OCR software available.  I suggest people download http://sourceforge.net/projects/vietocr/?source=typ_redirect.  There are more choices available at at https://code.google.com/p/tesseract-ocr/wiki/3rdParty.  I have gone for the vietocr product as it supports multiple languages.

–  To run the vietocr software you need two more bits of software Java and Ghostscript.  You can get Ghostscript from http://www.ghostscript.com/download/gsdnld.html and java from https://java.com/en/download/index.jsp.  When you install java you and ghostscript you need to add these to your path environment variable.  If you are not sure how to do this on your computer google it or ask / pay someone.

– Again vietocr comes packaged in a zip file which you will need to extract.

– If you are using a 64 bit windows PC you will get an error when you eventually try to run the software as it will not find the GhostScript software.  You need to copy the software from the GhostScript install directory at C:\Program Files\gs\gs9.15\bin  to wherever you have installed vietocr.  You will then need to rename all these GhostScript files and change where it says 64 to 32.

– To run vietocr you click will need to go into the vietocr directory that you extracted and click on the ocr.bat file.  If you have java installed this will launch a black command box called a console the a while after the vietocr application will appear.

–  You can load PDF and other such documents in vietocr using the file menu as you would expect.  You may find that if you try to load a document that has too many pages you get an out of memory error.  If this happens there is a Tools | Spilt PDF… option you can use to chop up your input document.  Once your document is imported you can convert it by clicking OCR.  Once you have text coverted you can change the font using the Format | Font option.

As of 11/03/2015 I have found that I now need to use the 32bit version GhostScript on my PC rather than the 64 bit which is nolonger recognised.  I assume that there has been a Microsoft update which has changed things.
