edgepaint:tldr:25467
This command is a shell command that uses several command-line tools to convert a Graphviz Graph Visualization (GV) file to a Portable Network Graphics (PNG) file, while applying some transformations on the graph.
Here is a breakdown of the command:
-
dot ${path-to-input-gv}
: Thedot
command is a Graphviz tool that takes a Graph Visualization file (${path-to-input-gv}
) as input and generates a graph layout. The output is in Graphviz's internal format. -
|
: This is a pipe symbol that connects the output of the previous command to the input of the next command, allowing them to be chained together. -
edgepaint
: This is a custom command (possibly a custom script or an external program) that acts as a filter or transformation on the graph. It may apply some alterations or manipulations to the graph's edges. -
|
: Another pipe symbol to connect the output of theedgepaint
command to the next command. -
dot -T ${png}
: This is another invocation of thedot
command. It takes the output from the previous command and converts it into a PNG image format (-T ${png}
). The-T
option specifies the output format, and${png}
is a variable that contains the desired extension for the output file (e.g., "png"). -
> ${path-to-output-png}
: This redirects the output of the previous command (the PNG image data) to a file specified by${path-to-output-png}
(the path to the desired location for the output PNG file). The>
symbol is used for output redirection.
In summary, this command takes a Graphviz GV file as input, processes it with the dot
command, applies the custom edgepaint
script or program, and then uses dot
again to convert the modified graph into a PNG file, saving it to the specified output location.
