8.5

Accepted values range from 0 to 1. The default value is 0.3, recommended values are between 0.05 and
0.30.
Delta Height
Defines the tolerance for the height and position difference between two target fragments. The higher the
number, the more difference between the fragment's height(the tallest font character's height)will be
accepted and the more vertical distance between fragments are accepted. Exponents, for example, are
higher and lower.
When this value is 0, no vertical shift is accepted between two fragments. When the value is 1, the second
text fragment can be shifted by as much as the height of the first fragment.
Accepted values range from 0 to 1. The default value is 0.15, recommended values are between 0.00 and
0.50.
Font Delta Height
Defines the tolerance for the difference in average height of fonts in the two target fragments. The higher the
number, the more difference in average font heights will be accepted. The average font height is bigger in
text written in uppercase than text written in lowercase.
At 0, the font size must be exactly the same between two fragments. At 1, a greater variance in font size is
accepted.
Accepted values range from 0 to 1. The default value is 0.65, recommended values are between 0.60 and
1.00.
Gap
Defines how spaces between two fragments are processed. If the space between two fragments is too small,
the text extraction will sometimes eliminate that space and count the two fragments as a single word. To
resolve this, the Gap setting can be changed. The lower this value, the higher the chance of a space being
added between two characters. A value too low may add spaces where they do not belong.
Accepted values range from 0 to 0.5. The default value is 0.3, recommended values are between 0.25 and
0.40.
