Gnome::Gsk4::RadialGradientNode
Description
A render node for a radial gradient.
Class initialization
new
:native-object
Create an object using a native object from elsewhere. See also Gnome::N::TopLevelSupportClass.
multi method new ( N-Object :$native-object! )
new-radialgradientnode
Creates a Gnome::Gsk4::RenderNode 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.
method new-radialgradientnode ( N-Object $bounds, N-Object $center, Num() $hradius, Num() $vradius, Num() $start, Num() $end, N-Object $color-stops, Int() $n-color-stops --> Gnome::Gsk4::RadialGradientNode \)
$bounds; the bounds of the node
$center; the center of the gradient
$hradius; the horizontal radius.
$vradius; the vertical radius.
$start; a percentage >= 0 that defines the start of the gradient around
$center
.$end; a percentage >= 0 that defines the end of the gradient around
$center
.$color-stops; a pointer to an array of Gnome::Gsk4::N-ColorStop 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; the number of elements in
$color-stops
.
Methods
