       gtk4-rendernode-tool show [OPTIONS...] <FILE>

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.

       --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 or tiff image.  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 poassible values
          for the RENDERER.

   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 major 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.`

                                                                           GTK4-RENDERNODE-TOOL()
