Line Angles
The position where the brightness changes is extracted as an edge and the
direction of the change in brightness is found. This direction is called the edge
code and it indicates the direction of the edge. The way in which black and

The level for extracting lines can be changed. There are 5 levels (1 to 5) and the default
setting is 3. Refer to the following examples and adjust the level as required.
To make a broken line into a single line To extract as separate lines
Change the
extraction level to
a larger value. Change the
extraction level to
a smaller value.
Change the extraction
level to a smaller
value. Change the extraction
