Overview
A render node controlling the color matrix of its single child node.
Defined in:
lib/gi-crystal/src/auto/gsk-4.0/color_matrix_node.crConstructors
-
.new(child : Gsk::RenderNode, color_matrix : Graphene::Matrix, color_offset : Graphene::Vec4) : self
Creates a
Gsk::RenderNode
that will drawn the child with color_matrix. -
.new
Initialize a new
ColorMatrixNode
.
Class Method Summary
-
.g_type : UInt64
Returns the type id (GType) registered in GLib type system.
Instance Method Summary
-
#==(other : self)
Returns
true
if this reference is the same as other. -
#child : Gsk::RenderNode
Gets the child node that is getting its colors modified by the given node.
-
#color_matrix : Graphene::Matrix
Retrieves the color matrix used by the node.
-

Constructor Detail
Creates a Gsk::RenderNode
that will drawn the child with color_matrix.
In particular, the node will transform the operation
pixel = color_matrix * pixel + color_offset
for every pixel.
