Constructor Detail

def : Gsk::RenderNode, color_matrix : Graphene::Matrix, color_offset : Graphene::Vec4) : self #

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.

def #

Initialize a new ColorMatrixNode.

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def child : Gsk::RenderNode #

Gets the child node that is getting its colors modified by the given @node.

def color_matrix : Graphene::Matrix #

Retrieves the color matrix used by the @node.

def color_offset : Graphene::Vec4 #

Retrieves the color offset used by the @node.
