linking distance


In OCR actions, specifies the maximum horizontal distance between adjacent characters for those characters to be treated as members of a single bitmap text fragment.

The linking distance is given as a percentage of the average height (not width) of the detected font sizes of the text on either side of the gap. Adjacent characters are grouped together as a fragment when the distance between each is less than the specified threshold value. If the horizontal spacing between two characters exceeds this threshold, they are treated as members of separate text fragments.
