"# Physical Metrics Parameters for `ggsave()`\n",
"\n",
"Parameters `dpi`, `w`, `h` and `unit` can be used to configure export to a raster image with required physical metrics. Aspect ratio must be maintained manually between `ggsize()` and `ggsave()`. Please note that using these parameters will disable the `scale` parameter."
