The SWF::Gradient Module

A gradient consists of a list of color values, each value with a set position. The gradient can be scaled to fill a given region and can appear as a linear gradient or a radial gradient (illustrated back in Figure 9-4). The color of the points between the two defined end points gradually transforms from the color of the first point to the color of the second.

A gradient is constructed by adding color entries at particular positions:

my $gradient = new SWF::Gradient( );
$gradient->addEntry(0.0, 255, 0, 0);
$gradient->addEntry(1.0, 255,255,255);
my $fill = $s->addFill($gradient);
$fill->scaleTo(.1);            # A method of the SWF::Fill object

See The SWF::Fill Module for additional methods for controlling gradient fills.
