Scan-See Sub-Menu – Mapping The Viewport
Anchor Line/Anchor Column
A location on the Scan-See display – the anchor – is chosen as a reference point.
Line Offset/Column Offset
A predefined displacement – the offset – is added to the location of the 7535/7530
cursor to create a point – the pivot . This pivot is mapped to the anchor, and
whatever is displayed in its vicinity is also displayed on the Scan-See.
For example:
• the anchor is chosen as (9,0) whereas “9” is the column and “0” is the line
(on the Scan-See display)
• the offset is chosen as (4,2)
• the cursor on the 7535/7530 is currently located at (7,5)
• the pivot would thus be located at (7+4, 5+2) or (11,7)
• and so the area displayed on the Scan-See will be:
(11–9,7–0) to (11–9+9,7–0+1) or (2,7) to (11,8).

These computations assume that “Wraparound” (described on page 315) is dis-
abled
(set to “N”) and that “Follow Cursor” (described on page 315) is enabled (set to
“Y”).
