=head1 NAME
-SDL::Color - a SDL perl extension
+SDL::Color - Format independent color description
=head1 SYNOPSIS
- $color = new SDL::Color ( -r => 0xde, -g => 0xad, -b =>c0 );
- $color = new SDL::Color -surface => $app, -pixel => $app->pixel($x,$y);
- $color = new SDL::Color -color => SDL::NewColor(0xff,0xaa,0xdd);
+ my $black = SDL::Color->new( 0, 0, 0);
+ my $color = SDL::Color->new(255, 0, 0);
+ my $r = $color->r; # 255
+ my $g = $color->g; # 0
+ my $b = $color->b; # 0
+ $color->g(255);
+ $color->b(255);
+ # $color is now white
=head1 DESCRIPTION
-C<SDL::Color> is a wrapper for display format independent color
-representations, with the same interface as L<SDL::Color>.
+C<SDL_Color> describes a color in a format independent way.
+
+=head1 METHODS
-=head2 new ( -color => )
+=head2 new ( $r, $g, $b )
-C<SDL::Color::new> with a C<-color> option will construct a new object
-referencing the passed SDL_Color*.
+The constructor creates a new color with the specified red, green and
+blue values:
-=head2 new (-r => , -g => , -b => )
+ my $color = SDL::Color->new(255, 0, 0);
-C<SDL::Color::new> with C<-r,-g,-b> options will construct both a SDL_Color
-structure, and the associated object with the specified vales.
+=head2 r
-=head2 new (-pixel =>, -surface =>)
+If passed a value, this method sets the red component of the color;
+if not, it returns the red component of the color:
-C<SDL::Color::new> with C<-pixel,-surface> options will generate a SDL_Color*
-with the r,g,b values associated with the integer value passed by C<-pixel>
-for the given C<-surface>'s format.
+ my $r = $color->r; # 255
+ $color->r(128);
-=head2 r ( [ red ] ), g( [ green ] ), b( [ blue ] )
+=head2 g
-C<SDL::Color::r, SDL::Color::g, SDL::Color::b> are accessor methods for
-the red, green, and blue components respectively. The color value can be set
-by passing a byte value (0-255) to each function.
+If passed a value, this method sets the green component of the color;
+if not, it returns the green component of the color:
-=head2 pixel ( surface )
+ my $g = $color->g; # 255
+ $color->g(128);
-C<SDL::Color::pixel> takes a C<SDL::Surface> object and r,g,b values, and
-returns the integer representation of the closest color for the given surface.
+=head2 b
-=head1 AUTHOR
+If passed a value, this method sets the blue component of the color;
+if not, it returns the blue component of the color:
