ProMAX Printing
Command Line UNIX Printing

Printing from ProMAX, creating a .cgm file:
1) determine trace density for length of plot (traces/cm) - X coord
2) determine time density for width of plot (cm/sec) - Y coord
3) Add to flow "Create CGM+ Plotfile"
4) Plotting Units - centimeters
5) Trace Space - X coord value
6) Time scale - Y coord value
7) End time - Msec
8) Timing Lines - 500 1000
9) Timing annotation increment - 500

Click "Add After"

10) Components List "Post> CDP > CDP"
11) Select CDPs to annotate - 1-10000(100) - frequency of annotation in ()

Flow history window appears after execution of flow

Information in this window will constitute side panel (click Exit)

when plot completes normally - cgmplot file will exist in directory where
data was (mcs class directory)

Here's the process, once you have a CGM file written to disk:
To preview the .cgm:

On a PC: Preview in Illustrator CS2
On a Linux:
For csh/tcsh users, in a terminal: type "source /opt/zps/pltx.login"
For bash users, in a terminal: type "source /opt/zps/pltx.profile"

Now type "zpreview". Alternatively, type "zps" to start the zps shell, then select the "CGM Previewer" from the "Applications" menu.

To Print Option 1:
Open the .cgm in Illustrator CS2 and print from the File pulldown menu.

To Print Option 2:
YOU MUST BE LOGGED IN AS lgc
1) start zps (type "zps"). If you recieve the message "zps: command not found", type "source /opt/zps/pltx.login", then repeat the zps command.
a) Click the "Applications" button and select "Job Submittal" from the menu.
b) Select the file from the left hand pane's file tree.
c) Select "medusa" as the print server
d) Select "karst" as the printer
e) Select "CGM" as the file type

3) Set any desired options in "PlotSize" submenu

4) Submit job when satisfied.

5) Use "User Console" feature of zps to watch progress of job.

Plotting .cgm files from the command line
YOU MUST BE LOGGED IN AS lgc
1) Create .cgm output file from SeisWorks
2) On the command line (in a terminal window):

zeh_plotfile

Answer the prompts:

File type: cgm
metafile name: the full path to your file (eg. /pa/eisoi/hmj_amplitude.cgm)
plotter name: karst
number of copies: 1

The program will report that the plot was successful if there are no errors. If the program doesn't report successful plotting then something is wrong. Double check the parameters entered above.

Wait for your plot to come out.
