gridpattern v1.4.2

Breaking Changes

• The "indented" (formerly "triangle") wave type now uses a wider stroke
  in order to better match the apparent stroke widths of the new wave types.
  Users who relied on the previous visual appearance should reduce density
  to compensate.

New Features

• New "hatch" pattern with corresponding grid.pattern_hatch() and names_hatch() (#97).

• New "line" pattern with corresponding grid.pattern_line().
  Unlike the "stripe" pattern which fills bands with solid colour,
  "line" draws stroked lines using the device's native line rendering,
  enabling all of R's built-in linetype values
  (including "dotdash", "twodash", and custom line types specified as hex strings per ?par).

• The preexisting "wave" pattern gains ten new type values, a reverse parameter, a stagger parameter, and names_wave (#100, #101).

• New mix_col() that mixes colors via Munsell color space using aqp::mixMunsell().
  Requires the suggested package {aqp}.

Bug fixes and minor improvements

• Fixes a bug where geometry-based patterns (e.g. "stripe", "crosshatch", "wave")
  could silently disappear in small viewports when pattern_key_scale_factor
  was a relatively large value (#95).

• The following "placeholder" pattern updates (#83):

  • The following placeholder pattern names are now serviced by placecats.com

    • "kitten" and "kittenbw"

  • The following placeholder pattern names are now serviced by placehold.co

    • "placeholder" and "placeholderbw"

  • The "placeholderbw" name now provides a pure black-and-white image (i.e. no grey).

• Fixes a bug where the "wavy" (aliases "sine", "undy") and "indented" (alias "triangle") wave types had an effective wavelength of (n-1)/n times the requested wavelength, where n is the number of wavelength-spaced grid positions spanning the viewport.
