`grid.pattern_magick()`

draws a `imagemagick`

pattern onto the graphic device.
`names_magick`

, `names_magick_intensity`

, and
`names_magick_stripe`

are character vectors of supported `type`

values
plus subsets for shaded intensity and stripes.

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 | Magick pattern types. |

fill | Fill colour |

scale | Extra scaling |

filter | Filter to use when scaling. |

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 54.

An object of class `character`

of length 21.

An object of class `character`

of length 19.

A grid grob object invisibly. If `draw`

is `TRUE`

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