This may be needed for various compiling options (e.g., png), running other extensions or performing other options only available via the shell API. Best practice is to avoid using this API except when absolutely necessary, since it is resource-intensive to invoke a new Inkscape instance. However, in any circumstance when it is necessary to call Inkscape, it is strongly recommended that you do so through this API, rather than calling it yourself, to take advantage of the security settings and testing functions.
