`grid.pattern_placeholder()`

draws a placeholder image pattern onto the graphic device.
`names_placeholder`

are character vectors of supported placeholder types.

grid.pattern_placeholder( x = c(0, 0, 1, 1), y = c(1, 0, 0, 1), id = 1L, ..., type = "kitten", alpha = gp$alpha %||% NA_real_, aspect_ratio = 1, key_scale_factor = 1, res = 72, default.units = "npc", name = NULL, gp = gpar(), draw = TRUE, vp = NULL ) names_placeholder

x | A numeric vector or unit object specifying x-locations of the pattern boundary. |
---|---|

y | A numeric vector or unit object specifying y-locations of the pattern boundary. |

id | A numeric vector used to separate locations in x, y into multiple boundaries.
All locations within the same |

... | Currently ignored |

type | Image source. |

alpha | Alpha (between 0 and 1) or |

aspect_ratio | Override aspect ratio |

key_scale_factor | Additional scale factor for legend |

res | Assumed resolution (in pixels per graphic device inch) to use when creating array pattern. |

default.units | A string indicating the default units to use if |

name | A character identifier. |

gp | An object of class |

draw | A logical value indicating whether graphics output should be produced. |

vp | A Grid viewport object (or NULL). |

An object of class `character`

of length 26.

A grid grob object invisibly. If `draw`

is `TRUE`

then also draws to the graphic device as a side effect.
