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, 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.


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.


Extract

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

--dir=DIRECTORY

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