Using the ImageShift utility through the command line interface

The procedures for configuring and running the ImageShift utility from the command line

interface are given below. To run the ImageShift utility from the command line interface,

you must utilize an imageshift file. An imageshift file specifies both the image and

parameters necessary to run the ImageShift utility.

To create an imageshift file:

1. Establish a session with the generator using either HyperTerminal over a serial

connection or Telnet over an Ethernet LAN. See “Configuring the generator’s serial

port” on page 32 or “Establishing a Telnet session with the generator” on page 34.

2. Set the path to the imageshift files using the ISHP command. For example:

ISHP tffs0/library/imageshifts

3. Create a new imageshift file using the ISHN command. For example:

ISHN Newshift

4. Define the imageshift file settings as shown in the example below:

ISHB //begins an imageshift editing session

XISH:SRCN /cache0/images/SMPTEBar //selects the SMPTEBar image

XISH:PATH 0,0 150,20 //sets the imageshift path x,y coordinates

XISH:TTYP 1 //sets the trace type to Repeat (1)

XISH:HINC 4 //sets the horizontal shift increment to 4

XISH:VINC 2 //sets the vertical shift increment to 2

XISH:TINC 5 //sets the time shift value to 5

ISHE //ends the imageshift editing session

5. Save the settings to the same imageshift file using the ISHS command, For example:

ISHS //saves the settings to the Newshift file
