Gsk-4.0 ▶ Gsk ▶ GLShaderNode

Draws the contents of a render node on a cairo context.

Typically, you'll use this function to implement fallback rendering of render nodes on an intermediate Cairo context, instead of using the drawing context associated to a Gdk.Surface's rendering buffer.

For advanced nodes that cannot be supported using Cairo, in particular for nodes doing 3D operations, this function may fail.

Retrieves the boundaries of the node.

The node will not draw outside of its boundaries.

Returns the type of the render node.

Gets an opaque rectangle inside the node that GTK can determine to be fully opaque.

There is no guarantee that this is indeed the largest opaque rectangle or that regions outside the rectangle are not opaque. This function is a best effort with that goal.

The rectangle will be fully contained in the bounds of the node.

Acquires a reference on the given Gsk.RenderNode.

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 Gsk.RenderNode.

If the reference was the last, the resources associated to the node are freed.

This function is equivalent to calling Gsk.RenderNode.serialize followed by GLib.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.

Loads data previously created via Gsk.RenderNode.serialize.

For a discussion of the supported format, see that function.
