NAME

Graphics::Primitive::Paint::Gradient::Linear - Linear color blending

DESCRIPTION

Graphics::Primitive::Paint::Gradient::Linear is a gradient along a line.

SYNOPSIS

   use Graphics::Primitive::Paint::Gradient::Linear;
 
   my $gradient = Graphics::Primitive::Gradient::Linear->new(
       line => Geometry::Primitive::Line->new(
           start => Graphics::Primitive::Point->new(x => 0, y => 0),
           end   => Graphics::Primitive::Point->new(x => 0, y => 10),
       )
   );
   $gradient->add_stop(0.0, $color1);
   $gradient->add_stop(1.0, $color2);
