Image::DS9 This class provides access to the DS9 image display and analysis program through its XPA access points. DS9 is a rather flexible and feature-rich image display program. Rather than extol its virtues, please consult the website in "REQUIREMENTS". While one could communicate with DS9 solely via the IPC::XPA class, this class provides a cleaner, less error prone interface, as it checks the passed commands and arguments for syntax and data type. It also cleans up returned data from DS9. To use this class, first construct a Image::DS9 object, and then apply its methods. It is possible to both address more than one DS9 with a single object, as well as having multiple Image::DS9 objects communicate with their own DS9 invocations. Eventually there will be documentation spelling out how to do this. INSTALLATION This is a Perl module distribution.
