gtk4-rendernode-tool(1) GTK commands gtk4-rendernode-tool(1) Name gtk4-rendernode-tool - GskRenderNode Utility SYNOPSIS gtk4-rendernode-tool [OPTIONS...] gtk4-rendernode-tool benchmark [OPTIONS...] gtk4-rendernode-tool compare [OPTIONS...] gtk4-rendernode-tool convert [OPTIONS...] gtk4-rendernode-tool extract [OPTIONS...] gtk4-rendernode-tool info [OPTIONS...] gtk4-rendernode-tool match [OPTIONS...] gtk4-rendernode-tool render [OPTIONS...] [] gtk4-rendernode-tool show [OPTIONS...] 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 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. 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 extracted 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 containing a color node. GTK gtk4-rendernode-tool(1)
