Other Systems Overview

• daemons:Two programs are packaged with DLXS software that allow the Middleware to work across machines (this might be an uncommon situation, but one we have here at DLPS)
  • xpatservd: Middleware running on one machine can access the XPat search engine on another machine to search data there
  • xpatviewd: Middleware running on one machine can request another machine to run other programs; e.g., the following two ....
• image conversion for Pageviewer functionality
  • tif2gif: converts tiff files to gif files
  • c42pdf: converts tiff files to pdf files
• MrSid (from LizardTech)
  • stores files, using wavelet compression
  • retrieves images from these files at multiple resolution

Note: in the near future there will likely be a name change perhaps with a collapsing of both daemons into one and a name change for tif2gif as we add support for conversion into PNG files as well.
