Declaration [src]

GskRenderNode*
gsk_radial_gradient_node_new (
  const graphene_rect_t* bounds,
  const graphene_point_t* center,
  float hradius,
  float vradius,
  float start,
  float end,
  const GskColorStop* color_stops,
  gsize n_color_stops
)

Description [src]

Creates a GskRenderNode that draws a radial gradient.

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

Parameters

bounds const graphene_rect_t*
 

the bounds of the node

 Ownership is not transferred to the callee
center const graphene_point_t*
 

the center of the gradient

 Ownership is not transferred to the callee
hradius float
 

the horizontal radius

vradius float
 

the vertical radius

start float
 

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

end float
 

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

color_stops An array of GskColorStop
 

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.

 The length of the array is in the n_color_stops argument
 Ownership is not transferred to the callee
n_color_stops gsize
 

the number of elements in color_stops

Return value

Returns: GskRadialGradientNode

A new GskRenderNode

Ownership of the data is transferred to the caller
