We have built three tools in javascript to provide key GUI to help SPC processing.  LMRK_DISPLAY.pgm or TEMPFILE.pgm gets copied to a webserver directory and displayed in a webpage that allows for measurement and analytical tools to aid in alignment.  It does not send the data back to SPC, but can be copied and pasted back into [[LITHOS]], [[AUTOREGISTER]], and [[REGISTER]].

== Webserver Requirements ==


== Working Directory Requirements ==

Within the working directory, you need to convert the LMRK_DISPLAY01.pgm and TEMPFILE.pgm to jpeg files in a webserver directory.  The following script is the minimum, but we've also made a more robust script (updateDisplay.sh) in /opt/local/spc.  Because we may have more than one person running SPC on a machine, we have set it up to have subdirectories.  If you need to use a subdirectory, then use one of the predefined initials, i.e. $webpath/data/ep/landmarks.jpg


Helpful script

You can run this script in the background when you are doing a lot of work. Every second, it will update the images used in the programs from your directory. 
Note - if your internet connection is slow, you might need to increase the sleep delay
{{{
#!/bin/bash

        convert LMRK_DISPLAY1.pgm $webpath/data/landmarks.jpg
        convert LMRK_DISPLAY1.pgm $webpath/data/autoregister.jpg
        convert TEMPFILE.pgm $webpath/data/register.jpg
        sleep 1
