Class Details

class Gsk.ColorMatrixNode

Bases:

Gsk.RenderNode

Abstract:

No

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

classmethod new(child, color_matrix, color_offset)

Parameters:

• child (Gsk.RenderNode) – The node to draw

• color_matrix (Graphene.Matrix) – The matrix to apply

• color_offset (Graphene.Vec4) – Values to add to the color

Returns:

A new GskRenderNode

Return type:

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.

get_child()

Returns:

The child that is getting its colors modified

Return type:

Gsk.RenderNode

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

get_color_matrix()

Returns:

a 4x4 color matrix

Return type:

Graphene.Matrix

Retrieves the color matrix used by the self.

get_color_offset()

Returns:

a color vector

Return type:

Graphene.Vec4

Retrieves the color offset used by the self.
