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.
