=head1 NAME
Demeter::UI::Wx::ColourDatabase - An objective interface to Wx::ColourDatabase
=head1 VERSION
This documentation refers to Demeter version 0.9.26.
=head1 SYNOPSIS
This is a pure perl implementation of Wx::ColourDatabase which
implements those colors named by X11's rgb.txt file and those
named by gnuplot.
use Demeter::UI::Wx::ColourDatabase;
my $cdb = Demeter::UI::Wx::ColourDatabase->new;
my $wx_color_object = $cdb -> Find("yellowgreen");
The semantics are very similar to those documented for
Wx::ColourDatabase, except that there is a constructor and object,
rather than just class methods.
=head1 DESCRIPTION
This is an object oriented interface to the functionality provided by
Wx::ColourDatabase and extended to include the named colors from X11's
rgb.txt file and from gnuplot. The purpose of this object is to
simplify the interaction with Wx colored windows while using named
colors. The C<Add>, C<Find>, and C<FindName> methods from
Wx::ColourDatabase are all implemented.
Most of this was swiped from a post to the wxperl-users mailing list,
L<http://www.nntp.perl.org/group/perl.wxperl.users/2007/06/msg3756.html>
by Mark Dootson on June 28, 2007.
Bruce added the interface to X11 and gnuplot colors.
=head1 DEPENDENCIES
Demeter's dependencies are in the F<Build.PL> file.
This requires Wx (of course) and L<File::Spec> as well as files from a
properly installed Demeter distribution.
=head1 BUGS AND LIMITATIONS
Please report problems to the Ifeffit Mailing List
(L<http://cars9.uchicago.edu/mailman/listinfo/ifeffit/>)
Patches are welcome.
