Re: [foxboro] DM optimization in 6.5.1

Ed,

You can use the pdfpack tool in /usr/fox/wp/bin to help with this problem.  The
pdfpack tool in /usr/fox/wp/bin is not the same as the one in /usr/foxbin (or
/usr/fox/disp_tools).  Make sure you fully path the command to get the right
tool.  They are both scripts that are wrappers for an executable.

For example, if your graphics files are in directories under /usr/disp:
cd /usr/disp
/usr/fox/wp/bin/pdfpack -r -5 *

The -r tells pdfpack to process a list of files, recursively.
The -5 tells it to process only 50 series files.
The * is a wildcard.
All display manager files in /usr/disp and in all directories under /usr/disp
will be processed.

It's my understanding that pdfpack for 50 series does not optimize the displays,
but rather clears the previous optimization.  This reduces your callup time from
20+ seconds on the first callup to only a few extra seconds on the first callup.
 There will still be a delay on the first callup of a graphic.

To speed things up even further, you can automate the initial graphics callup by
writing a script using the pref command.  Because pdfpack gives you a list of
all the files it processes, and which ones it packed, you can do the following
to save a record:

cd /usr/disp
/usr/fox/wp/bin/pdfpack -r -5 * | tee /opt/myscripts/displays.list

This saves a list of processed files in /opt/myscripts/displays.list

To call each one of these displays and allow 5 seconds for optimization, you can
use the following script:

#!/bin/sh
### cycle through dm graphics based on list generated by pdfpack ###
for DISP in `awk '/PACKED/{print $3}' /opt/myscripts/displays.list`
do
### send display to screen ###
  /usr/local/pref -AW5101 dmcmd $DISP
  sleep 5
done

When typing this script, watch the difference between the backquotes which
execute the entire awk command and the normal single quotes which isolate
/PACKED/{print $3} portion of the command.  Change the -AW5101 to the name of
the display manager you are going to send the graphics to.
