NAME

       gtk4-rendernode-tool - GskRenderNode Utility

SYNOPSIS

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

       gtk4-rendernode-tool benchmark [OPTIONS...] <FILE>
       gtk4-rendernode-tool compare [OPTIONS...] <FILE1> <FILE2>
       gtk4-rendernode-tool info [OPTIONS...] <FILE>
       gtk4-rendernode-tool render [OPTIONS...] <FILE> [<FILE>]
       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()
