Constructor Details

#initialize(bounds, center, hradius, vradius, start, end, color_stops, n_color_stops) ⇒ Gsk::RepeatingRadialGradientNode

Creates a GskRenderNode that draws a repeating radial gradient.

The radial gradient starts around center. The size of the gradient is dictated by hradius in horizontal orientation and by vradius in vertical orientation.

Parameters:

• bounds (Graphene::Rect) —

  the bounds of the node

• center (Graphene::Point) —

  the center of the gradient

• hradius (Gsk::gfloat) —

  the horizontal radius

• vradius (Gsk::gfloat) —

  the vertical radius

• start (Gsk::gfloat) —

  a percentage >= 0 that defines the start of the gradient around center

• end (Gsk::gfloat) —

  a percentage >= 0 that defines the end of the gradient around center

• color_stops (Array<Gsk::ColorStop>) —

  a pointer to an array of GskColorStop defining the gradient. The offsets of all color stops must be increasing. The first stop's offset must be >= 0 and the last stop's offset must be <= 1.

• n_color_stops (Integer) —

  the number of elements in color_stops
