DESCRIPTION
       gtk4-rendernode-tool can perform various operations on serialized rendernodes.

COMMANDS
   Information
       The  info  command  shows general information about the rendernode, such as the number of nodes, and the depth of the
       tree.

   Showing
       The show command displays the rendernode.

       --offload

       Puts the node into a GraphicsOffload. Intended for testing offloading capabilities of simple rendernodes.

       --undecorated

       Removes window decorations. This is meant for rendering of exactly the rendernode without any titlebar.

   Rendering
       The render command saves a rendering of the rendernode as a png, tiff or svg image or as pdf document.  The  name  of
       the file to write can be specified as a second FILE argument.

       --renderer=RENDERER
	  Use the given renderer. Use --renderer=help to get a information about possible values for the RENDERER.

       --dont-move

       Keep the node position unchanged, relative to the pixel grid.

   Benchmark
       The benchmark command benchmarks rendering of a node with the existing renderers and prints the runtimes.

       --renderer=RENDERER
	  Add the given renderer. This argument can be passed multiple times to test multiple renderers. By default, all ma‐
	  jor GTK renderers are run.

       --runs=RUNS
	  Number of times to render the node on each renderer. By default, this is 3 times.  Keep in mind that the first run
	  is often used to populate caches and might be significantly slower.

       --no-download
	  Do not attempt to download the result. This may cause the measurement to not include the execution of the commands
	  on the GPU. It can be useful to use this flag to test command submission performance.

   Compare
       The  compare  command compares the rendering of a node with a reference image, or the renderings of two nodes, or two
       images. If any differences are found, the exit code is 1. If the images are identical, it is 0.

       --renderer=RENDERER
	  Use the given renderer.

       --output=FILE
	  Save the differences as a png image in FILE.

       --quiet
	  Don't write results to stdout.

   Convert
       The convert command converts a symbolic SVG icon into a node and writes the result to stdout.

       --recolor
	  If this option is used, the resulting node will have its symbolic colors replaced by the values given to the --fg,
	  --success, --warning and --error options. Otherwise, the node will have the unreplaced colors, which can be useful
	  to diagnose rendering issues.

       --fg=COLOR --success=COLOR --warning=COLOR --error=COLOR
	  Set the symbolic colors to recolor the icon with. If not specified, default colors are used.

       --size=SIZE
	  Sets the size to render the icon at. The size can be either a number or a string of the form WIDTHxHEIGHT.

   Extract
       The extract command saves all the data urls found in a node file to a given directory. The file	names  for  the	 ex‐
       tracted files are derived from the mimetype of the url.

       --dir=DIRECTORY
	  Save extracted files in DIRECTORY (defaults to the current directory).

   Matching
       The  match  command  allows to count occurrences of node patterns in a larger node. The syntax for patterns allows to
       describe collections of nodes with given types, like this:
	  (mask . color)

	  Match mask nodes with any source child and a color node as mask child.

	  (rounded-clip linear-gradient)

	  Match rounded clip nodes containing a linear gradient.

	  (container 2 color (fill color))

	  Match containers with 2 children, the first of which is a color node and the second of which is a fill  node	con‐
	  taining a color node.
