Width table
To tune the width table correctly, you need to define width interval boundaries so
that the objects obtained after vectorization of raster lines with the same width fit in
the same width interval.
The width table can contain any number of width intervals. Each interval is defined
by two values – a lower and high width boundary which recognized objects must fall
into get into the specified interval. Width, color and layer are defined to each
interval, and these properties are assigned to the objects that fall into each interval
according to its width. Real raster lines widths vary around their true value. For
example, if you vectorize raster lines with a width of 0.25 mm, you can obtain
objects with widths from 0.18 to 0.33 mm, and lines with width of 0.5 mm turning
into vector objects with width from 0.35 up to 0.7 mm.
Description
If this checkbox is off, then the program assigns to objects the
specified values of AutoCAD color and layer properties, the
weight of objects' lines is set according to the widths of the
appropriate raster lines.
Allows you to create and delete width intervals in the table.
Allows you to edit objects width intervals, to assign color, layer,
and weight of the line to an interval.
