7.4

Font size difference: Indicates the smallest acceptable factor between maximum and minimum font size within one line. A
value of 0.60 means that with a ratio from maximum to minimum font size (in points), that is less than 0.60, two text passages
are not recognized as belonging together. For example, if two text passages are formatted with different font sizes. Passage 1
with 10, passage 2 with 18 point. The ratio 0.56 is smaller than the adjusted value 0.60. Therefore those two text passages
are recognized as not belonging together.
Word distance: Indicates the largest acceptable distance between two text passages, so that they are still recognized as
belonging together. This the factor the font's mean character width is multiplied with. The value for the mean character width
is taken from the corresponding font's attributes (for texts which are printed justified, it is suggested to raise this value up to
about 2). For example, if the mean character width of the font example shown here corresponds to the width of the blank char-
acter (for other fonts it may be another sign). There is another text passage found whose horizontal distance is even bigger
than the first one's mean character width, multiplied by factor 1.0. The two text passages are found to not belong together.
Vertical distance: Indicates the biggest acceptable vertical distance between two text passages so that they're still rec-
ognized as belonging together. This is the factor the font's height and size is multiplied with. The value for the font's height
therefore is taken from the corresponding font's attributes. For example, if the height of that font example in 10 point size is
0.32 cm. There is a passage found that is positioned 0.15 cm above - which means 0.15/0.31 = 0.48 < 0.50 - the previous text
passage. So the two passages are not recognized as belonging together.
