Notes		  

Any custom variables that should be passed to the Optical Character Recognition (OCR) engine.

For example the Tesseract OCR engine accepts a variable named "tessedit_char_whitelist" which can be used to specify a reduced range of characters to recognize. This can be useful if, say, you wish to restrict the character set to numeric digits.

If the value of this property is null then no variables will be passed.

 

    

Example		  

None.
