Creates a GskRenderNode 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.
The node to draw
The matrix to apply
Values to add to the color
Draw the contents of node to the given cairo context.
Typically, you'll use this function to implement fallback rendering
of GskRenderNodes on an intermediate Cairo context, instead of using
the drawing context associated to a [classGdk.Surface]'s rendering buffer.
For advanced nodes that cannot be supported using Cairo, in particular for nodes doing 3D operations, this function may fail.
Gets the child node that is getting its colors modified by the given node.
Retrieves the color offset used by the node.
Returns the type of the node.
Acquires a reference on the given GskRenderNode.
Serializes the node for later deserialization via
gsk_render_node_deserialize(). No guarantees are made about the format
used other than that the same version of GTK will be able to deserialize
the result of a call to gsk_render_node_serialize() and
gsk_render_node_deserialize() will correctly reject files it cannot open
that were created with previous versions of GTK.
The intended use of this functions is testing, benchmarking and debugging. The format is not meant as a permanent storage format.
Releases a reference on the given GskRenderNode.
If the reference was the last, the resources associated to the node are
freed.
This function is equivalent to calling [methodGsk.RenderNode.serialize]
followed by [funcGLib.file_set_contents].
See those two functions for details on the arguments.
It is mostly intended for use inside a debugger to quickly dump a render node to a file for later inspection.
the file to save it to.
Loads data previously created via [methodGsk.RenderNode.serialize].
For a discussion of the supported format, see that function.
