View Image Symbols
The View Image display contains a number of icons and
other symbols, most of which pertain to the View Port
adjustments. These are numbered in Figure 6.3 (page
+I), and they represent the following functions:
1. Horizontal View Port Marker - This symbol
indicates the specific horizontal segment of the Lime
Image that appears in the View Port. The vertical dotted
lines in Figure 6.3 (page 6A) show this segment in
the Line Image. The shorter the horizontal marker, the
smaller the segment appearing in the View Port, and the
higher the horizontal ‘magnification.”
2. Panning Arrows -These arrow icons prompt you to
press the left or right arrow key (or “click” the icon
directly with the mouse cursor) to move the horizontal
view port marker left or right. The marker does not
change its length-just its position. (You can use
Control/Arrow to move the marker in larger
increments; and, you can use the Home and End key to
move the marker fully left and right, respectively.) The
effect is to select a different segment of the Line Image.
3. Microscope/Minus - This icon prompts you to press
the minus (-) key, (or “click” the icon directly with the
mouse cursor) to extend the horizontal marker from the
right end (the left end always remains fixed, unless the
right end is at its rightmost position). The effect is to
“zoom out” from the View Port image.
4. Microscope/Plus - This icon prompts you to press the
(-), or minus, key (or “click” the icon directly with the
mouse cursor) to contract the horizontal marker from
the right end (the left end remains fared). The effect is
to “zoom in” on the View Port image.
5. Vertical View Port Marker-This symbol indicates
the specific vertical segment of the Line Image that
appears in the View Port. The horizontal dotted lines in
Figure 6.3 (page 6-4) show this segment in the Line
Image. The shorter the vertical marker, the smaller the
Lie Image segment appearing in the View Port (and
the higher the vertical “magnification”).
6. Limit Selector Arrow - This arrow symbol points to
the upper or lower end of the vertical view port marker,
whichever you designate to move up or down when you
use the up (8) and down (9) arrow keys.
