by the coordinates to move the cursor left or right until it appears on the digit in the
X coordinate. Adjust the value of the setting up or down by pressing the + or - keys.
b. To specify the Y Start Point, position the blinking cursor on the digits of the Y
coordinate you wish to change. To do this, press the soft key adjacent to the arrow
by the coordinates to move the cursor left or right until it appears on the digit in the
Y coordinate. Adjust the value of the setting up or down by pressing the + or - keys.
7. To set the ending point of the image shift, press the soft key to the right of Start Point.
The following settings appear on the 882's display.
Path
<- End Point
X Y
100 100
You can set the ending coordinates of the image travel as follows:
a. To specify the X End Point, position the blinking cursor on the digits of the X
coordinate you wish to change. To do this, press the soft key adjacent to the arrow
by the coordinates to move the cursor left or right until it appears on the digit in the
X coordinate. Adjust the value of the setting up or down by pressing the + or - keys.
b. To specify the Y End Point, position the blinking cursor on the digits of the Y
coordinate you wish to change. To do this, press the soft key adjacent to the arrow
by the coordinates to move the cursor left or right until it appears on the digit in the
Y coordinate. Adjust the value of the setting up or down by pressing the + or - keys.
Note: The movement that you see may not always correspond to the settings for HInc
and VInc. The reason is that the number of shifts from start point to end point is
determined by the quotient of the total travel in the horizontal (pixels) and vertical (lines)
directions and the total increment defined. The lowest quotient of the two (horizontal
vs. vertical) will determine how many shifts the utility will make from start point to end
point. For example, if the start point is 0,0 and the end point is 100,100. An HInc setting
of 10 and a VInc setting of 20 will result in 5 shift movements (100/20 = 5). The 882 will
not produce shifts of 10 horizontal pixels per increment because it cannot move from 0
to 100 in 5 shifts by only moving 10 horizontal increments.
