gridpattern v0.3.1

Breaking Changes

• The package {magick} has been downgraded from "Imports" to "Suggests" (#44).
  You'll need to manually install {magick} with install.packages("magick")
  in order to use the following "array" patterns:

  • "gradient" (but only if use_R4.1_gradients is FALSE)
  • "image"
  • "magick"
  • "placeholder"
  • "plasma"

New Features

• The following package option ggpattern_res can now be set by options().
  It controls default "raster" image pattern resolution (pixels per inch).
  Defaults to 72 (pixels per inch).

• grid.pattern_polygon_tiling() now supports the following additional polygon tiling type's (#42):

  • "rhombille" implements a rhombille tiling of rhombi (#37)
  • "tetrakis_square" implements a tetrakis square tiling of isosceles right triangles (#38)
  • "2*.2**.2*.2**" implements a polygon tiling made of rhombi.
  • "2**.3**.12*" implements a polygon tiling made of rhombi, triangles, and twelve-pointed stars.
  • "3.3.3.3**" implements a polygon tiling made of triangles.
  • "3.3*.3.3**" implements a regular (star) polygon tiling made of triangles and three-pointed stars.
  • "3.3.3.12*.3.3.12*" implements a regular (star) polygon tiling made of triangles and twelve-pointed starts.
  • "3.3.8*.3.4.3.8*" implements a regular (star) polygon tiling of triangles,
    squares, and eight-pointed stars.
  • "3.3.8*.4**.8*" implements a regular (star) polygon tiling made of triangles, four-pointed stars,
    and eight-pointed stars.
  • "3.4.6.3.12*" implements a regular (star) polygon tiling made of triangles, squares,
    hexagons, and twelve-pointed stars.
  • "3.4.8.3.8*" implements a regular (star) polygon tiling of triangles,
    squares, octagons, and eight-pointed stars.
  • "3.6*.6**" implements a regular (star) polygon tiling made of triangles and six-pointed stars.
  • "4.2*.4.2**" implements a polygon tiling made of squares and rhombi.
  • "4.4*.4**" implements a regular (star) polygon tiling made of squares and four-pointed stars.
  • "4.6.4*.6" implements a regular (star) polygon tiling made of squares, hexagons, and four-pointed stars.
  • "4.6*.4.6*.4.6*" implements a regular (star) polygon of squares and six-pointed stars.
  • "4.8*.4**.8*" implements a polygon tiling of squares and eight-pointed stars.
  • "6.6*.6.6*" implements a regular (star) polygon of hexagons and six-pointed stars.
  • "8.4*.8.4*" implements a regular (star) polygon of octagons and four-pointed stars.
  • "9.3.9.3*" implements a regular (star) polygon of triangles, nonagons, and three-pointed stars.
  • "12.3*.12.3*" implements a regular (star) polygon tiling made of dodecagons and three-pointed stars.
  • "12.12.4*" implements a regular (star) polygon tiling made of dodecagons and four-pointed stars.
  • "18.18.3*" implements a regular (star) polygon tiling made of eighteen-sided polygons and three-pointed stars.

• grid.pattern_regular_polygon() now supports a "tetrakis_left" shape and "tetrakis_right" shape
  which both draw an isosceles right triangle (one oriented left and one oriented right) as well as a
  "rhombille_rhombus" shape which draws a rhombus.
  These are non-regular polygons intended to help produce tetrakis square and rhombille polygon tilings.

Bug fixes and minor improvements

• star_angle() and star_scale() now handle the n_vertices == 2 case
  (a "two-pointed star" polygon is a rhombus).
• Fixes grid.pattern_gradient() when use_R4.1_gradients=TRUE to better
  match behavior when use_R4.1_gradients=FALSE.
• Now allows alpha values to be specified
  within the fill (and fill2) colour strings for
  gridpattern_plasma() and gridpattern_gradient() (when use_R4.1_gradients=FALSE).
• In pattern_square() for the "horizontal" and "vertical" types the value 1L is
  now guaranteed to be in the center of the pattern (#46).
