NAME

Image::DS9::Constants::V0 - predefined constants

VERSION

version v1.0.1

SYNOPSIS

            

              
              
# import all of the constants
use Image::DS9::Constants;
# import a subset
use Image::DS9::Constants qw( _const1 _const2 );
# change the prefix
use Image::DS9::Constants Prefix => 'X_';
# change the prefix and import a subset
use Image::DS9::Constants
   Prefix => 'X_', qw( X_const1 X_const2 );
# list the available constants;
use Image::DS9::Constants;
Image::DS9::Constants::list;
Image::DS9::Constants::list( Prefix => 'X_' );
            
          

DESCRIPTION

This module provides a large number of Perl constants for option strings used to communicate with DS9. The constants have a default prefix of _, which may be changed by the user (see "SYNOPSIS"). See the documentation for the Perl constant module for information on what constitutes a legal constant name (for instance, two leading underscores are not allowed).

To determine what the constants are, use the list function:

            

              
              
perl -MImage::DS9::Constants \
        -e 'Image::DS9::Constants::list'
            
          

This will print a listing of all of the constants. To specify a different prefix,

            

              
              
perl -MImage::DS9::Constants \
        -e 'Image::DS9::Constants::list( Prefix => "XX")'
