===================================================================

.. currentmodule:: gi.repository.Gsk





.. class:: ColorMatrixNode(*args, **kwargs)
   :no-contents-entry:


Superclasses: :class:`~gi.repository.Gsk.RenderNode`





A render node controlling the color matrix of its single child node.


Constructors

   .. classmethod:: new(child: ~gi.repository.Gsk.RenderNode, color_matrix: ~gi.repository.Graphene.Matrix, color_offset: ~gi.repository.Graphene.Vec4) -> ~gi.repository.Gsk.ColorMatrixNode

      Creates a ``GskRenderNode`` that will drawn the ``child`` with
      ``color_matrix``\.

      In particular, the node will transform colors by applying

      pixel = transpose(color_matrix) \* pixel + color_offset

      for every pixel. The transformation operates on unpremultiplied
      colors, with color components ordered R, G, B, A.






      :param child: The node to draw

      :param color_matrix: The matrix to apply

      :param color_offset: Values to add to the color

   .. method:: get_child() -> ~gi.repository.Gsk.RenderNode

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









   .. method:: get_color_matrix() -> ~gi.repository.Graphene.Matrix

      Retrieves the color matrix used by the ``node``\.









   .. method:: get_color_offset() -> ~gi.repository.Graphene.Vec4

      Retrieves the color offset used by the ``node``\.
