Exercise 6: Using The Zoom/Pan Function - Tektronix 4106 Operator's Manual

GETTING ACQUAINTED
For these exercises, use the last option :
Press the Menu key to exit the Set Color function and save your colors.
When you define colors , you ' ll notice that a range of HLS values result in a single
color. For example , HLS values of 100° , 30% , and 100% will result in the same red
color as the HLS values of 120° , 30% , and 100%. This happens because you can
specify a greater number of HLS values than there are colors that the terminal can
display.
Remember that how a given color is perceived depends on a number of factors ,
including how much of the color is displayed and which colors surround it.
After changing colors , you may want to make a hard copy of the color map to show
the current color assigned to each index . Use the SCopy key.
EXERCISE 6: USING THE ZOOM/ PAN FUNCTION
This exercise introduces the terminal 's Zoom/Pan feature . (If you are doing this
exercise out of sequence , do Exercise 1, do the steps of Creating a Graphics Image
in Exercise 4, and do the steps of Using the Color Map in Exercise 5.)
To fit on the terminal screen , a large image may have to be reduced so much that
you can 't see its detail. The Zoom/Pan functions let you select a portion of a
displayed image and expand it to reveal more of its detail.
This exercise will help you:
• Use Zoom to expand a portion of the graphics image .
• Use Pan to move around the graphics image.
• Use general-purpose viewing functions to update or restore the graphics image
or to select a view.
