| Abstract: |
This paper describes our application of the X Public Access (XPA) interface to the new version of SAOimage. XPA allows an Xt program to define named public access points through which data and commands can be exchanged with external programs. It makes possible the external control of the program's main functions, including image display, image zoom and pan, color map manipulation, cursor/region definition, and frame selection. It also supports ``externalization'' of internal algorithms such as file access and scaling. Finally, we describe how XPA is used to support user-configurable ``quick-look'' analysis of image data and bi-directional communication with other processes. |
