ggpattern 1.1.3

Bug fixes and minor improvements

• Added alt text to vignette and README images.
• Added missing package anchors to a few Rd cross-references (#128).

ggpattern 1.1.1

Breaking changes

• The argument binwidth has been removed from geom_bar_pattern(). This argument was deprecated with ggpattern 0.1.0 (2020-04-01).
• The draw_key_polygon_pattern() called by geom_sf_pattern() is now passed in its actual aspect ratio (instead of 1). This may cause your legends to geom_sf_pattern() to look different.

Deprecated features

• In line with upstream changes in {ggplot2} the trans argument has been deprecated in various scales functions. Use the new transform argument instead (#113).
• outline.type = "legacy" is now formally deprecated in geom_area_pattern() and geom_ribbon_pattern(). Use outline.type = "full" instead. outline.type = "legacy" was deprecated with ggpattern 0.1.0 (2020-04-01) but this is the first time outline.type = "full" has been supported as an alternative.

New features

• Geoms now more consistently expose the lineend and linejoin parameters (#94). This matches a similar upstream change in ggplot2 3.4.0.

• geom_area_pattern() and geom_ribbon_pattern() now accept outline.type = "lower" and outline.type = "full". geom_density_pattern() now exposes the outline.type parameter.

• geom_bar_pattern() and geom_col_pattern() now accept parameter just. The just parameter was added to ggplot2::geom_bar() and ggplot2::geom_col() with ggplot2 3.4.0.

• geom_boxplot_pattern() now accept the outliers and staplewidth parameters. The outliers and staplewidth parameters were added to geom_boxplot() in ggplot2 3.5.0.

• geom_sf_pattern() now accepts the arrow parameter. The arrow parameter was added to geom_sf() in ggplot2 3.5.0.

• geom_violin_pattern() now accepts the bounds parameter. The bounds parameter was added to geom_violin() in ggplot2 3.5.0.

• Each pattern aesthetic may now be a list of vectors with each list element providing that aesthetic for a different pattern (#100). Most builtin {gridpattern} "geometry" patterns support multiple fill colors etc. which previously we could only access in {ggpattern} via custom patterns.

• The fill, pattern_fill, and pattern_fill2 aesthetics may now be (a list of) gradient/pattern fills (in addition to color strings) (#112). Note using gradient/pattern fills will require R (>= 4.2), a graphics device with support for the gradient/pattern fill feature, and will work only for a subset of patterns (i.e. most of the "geometry" patterns). Use of just color fills should continue to work on a wider variety of R versions, graphics devices, and patterns.

• {ggpattern} now supports the pattern_units aesthetic (#81). Supported by most "geometry" patterns. It sets the grid::unit() used by the pattern_spacing, pattern_xoffset, pattern_yoffset, and (for the "wave" pattern) the pattern_frequency aesthetics. Default is "snpc" while "cm" and "inches" are likely alternatives.

• geom_bin_2d_pattern() is now an alias for geom_bin2d_pattern(). This matches {ggplot2} which has both geom_bin_2d() and geom_bin2d().

Bug fixes and minor improvements

• draw_key_boxplot_pattern(), draw_key_crossbar_pattern(), and draw_key_polygon_pattern() aspect_ratio argument now defaults to get_aspect_ratio().
• Several (continuous) scales now have an ... argument which will be passed to ggplot2::continuous_scale().
• The default na.value for scale_pattern_continuous(), scale_pattern_discrete(), and scale_pattern_manual() is now "none" (#107).

ggpattern 1.0.1

Deprecated features

• In line with upstream changes in {ggplot2} a linewidth aesthetic has been introduced and supersedes the size aesthetic for scaling the width of patterned area border lines (#82). size will remain functioning but deprecated for these geoms and it is recommended to update all code to reflect the new aesthetic.
  Continue to use the size aesthetic to adjust the size of any points in geom_sf_pattern().

ggpattern 1.0.0

Bug fixes and minor improvements

• Fixes bug in "image" pattern when pattern_type = "tile" (#37). Transparent parts of tiled images are now consistently transparent. We now support the pattern_gravity aesthetic when pattern_type = "tile".

ggpattern 0.4.2

Breaking changes

• To turn off "clipping" certain built-in patterns with the new R 4.1 graphic features and instead use a raster image approximation one should now use options(ggpattern_use_R4.1_masks = FALSE) instead of options(ggpattern_use_R4.1_clipping = FALSE). Alternatively, using options(ggpattern_use_R4.1_features = FALSE) to turn off all R 4.1 features will continue to work.

• {ggpattern} removes the following data/functions which were deprecated in a previous version of {ggpattern}:

  • convert_polygon_df_to_polygon_grob()
  • convert_polygon_df_to_polygon_sf()
  • convert_polygon_sf_to_polygon_df()

• Defunct functions are no longer exported.

New features

• {ggpattern} now supports geom_histogram_pattern() (#71)

Bug fixes and minor improvements

• geom_sf_pattern() and geom_polygon_pattern() now support polygons with holes by using "alpha masking" instead of a "clipping path". If R 4.1 alpha mask feature is not supported by the active graphics device (or the masking feature is declined) we use a raster image approximation of the pattern. Resolution of the raster approximation can be adjusted by the pattern_res aesthetic whose default in turn can be adjusted by the "ggpattern_res" global option.

  This change fixes patterns filling holed polygons in certain graphic devices (#68). This change fixes patterns sometimes escaping plot window (#60).

• draw_key_polygon_pattern(), GeomMapPattern, GeomPolygonPattern, and GeomSfPattern now draws a "border" grob on top of the "pattern" grob (#72).

• Continuous "pattern_colour", "pattern_fill", and "pattern_fill2" color scales' default "colourbar" guide support should now work.

• scale_pattern_size_continuous() now uses "pattern_size" aesthetic instead of "size" aesthetic in underlying ggplot2::continuous_scale() call.

• We now export scale_pattern_alpha() which is an alias of scale_pattern_alpha_continuous().

ggpattern 0.3.1

Breaking changes

{ggpattern} removes the following data/functions which were deprecated in a previous version of {ggpattern}:

• calculate_bbox_polygon_df()
• convert_img_to_array()
• convert_polygon_df_to_alpha_channel()
• create_gradient_img()
• fetch_placeholder_img()
• fill_area_with_img()
• magick_filter_names, instead use magick::filter_types()
• magick_gravity_names, instead use magick::gravity_types()
• magick_pattern_intensity_names, instead use gridpattern::names_magick_intensity
• magick_pattern_names, instead use gridpattern::names_magick
• magick_pattern_stripe_names, instead use gridpattern::names_magick_stripe
• placeholder_names, instead use gridpattern::names_placeholder
• rotate_polygon_df()

Deprecated features

{ggpattern} now deprecates the following data/functions, they may be removed in a future version of {ggpattern}:

• convert_polygon_df_to_polygon_grob()
• convert_polygon_df_to_polygon_sf()
• convert_polygon_sf_to_polygon_df()

New features

• {ggpattern} now supports the following aesthetics (#45):

  • pattern_grid: Supported by most "geometry" patterns. Default is "square" while "hex" and "hex_circle" allow hexagonal layouts.
  • pattern_res: Supported by "array" patterns. Allow user to explicitly set resolution of image-based patterns.
  • pattern_rot: Used by "pch", "regular_polygon", "rose", and "text" patterns to rotate symbol within pattern. 'rot' is parameter used in grid:textGrob() to indicate rotation and pattern_angle already used to rotate entire pattern.

Bug fixes and minor improvements

• geom_polygon_pattern() and geom_sf_pattern() now support polygons with holes (#26, #44). If R 4.1 clipping features are not supported by the graphic device (or the clipping feature is declined) we must use a raster image approximation of the pattern. Resolution of the raster approximation can be adjusted by the pattern_res aesthetic whose default in turn can be adjusted by the "ggpattern_res" global option.

ggpattern 0.2.0

Breaking changes

{ggpattern} now uses {gridpattern} to generate pattern grobs. This means there are minor tweaks to visual behavior:

• 'pattern_spacing', 'pattern_xoffset', and 'pattern_yoffset' are now interpreted as 'spnc' units instead of 'npc' units. and the center of the pattern "grid" is now the center of the viewport. To exactly restore the original appearance of {ggpattern} "geometry" patterns one may need to tweak the 'pattern_density', 'pattern_spacing', 'pattern_xoffset', and/or 'pattern_yoffset' aesthetics.
• The resolution of "array" patterns should be close but not identical to before.
  In particular placeholder images will likely be different.
• Custom {ggpattern} patterns can no longer use the same name as a {ggpattern} / {gridpattern} builtin pattern and an error will be thrown if you try to do so.

The following functions copied from {ggplot2} are no longer exported by {ggpattern}:

• alpha(), instead use ggplot2::alpha() or scales::alpha()
• flip_data(), instead use ggplot2::flip_data()
• flipped_names(), instead use ggplot2::flipped_names()
• gg_dep(), instead use ggplot2::gg_dep()
• has_flipped_aes(), instead use ggplot2::has_flipped_aes()
• remove_missing(), instead use ggplot2::remove_missing()
• should_stop(), instead use ggplot2::should_stop()
• waiver(), instead use ggplot2::waiver()

Deprecated features

{ggpattern} now deprecates the following data/functions, they may be removed in a future version of {ggpattern}:

• calculate_bbox_polygon_df()
• convert_img_to_array()
• convert_polygon_df_to_alpha_channel()
• create_gradient_img()
• fetch_placeholder_img()
• fill_area_with_img()
• magick_filter_names, instead use magick::filter_types()
• magick_gravity_names, instead use magick::gravity_types()
• magick_pattern_intensity_names, instead use gridpattern::names_magick_intensity
• magick_pattern_names, instead use gridpattern::names_magick
• magick_pattern_stripe_names, instead use gridpattern::names_magick_stripe
• placeholder_names, instead use gridpattern::names_placeholder
• rotate_polygon_df()

New features

• {ggpattern} now supports all patterns provided by {gridpattern}. In particular {gridpattern} provides the following "new" patterns:

  • "ambient" (the suggested package {ambient} must be installed)
  • "pch"
  • "polygon_tiling"
  • "regular_polygon"
  • "rose"
  • "text"
  • "wave"
  • "weave"

• 'pattern_fill2' can now be used to set the fill for the vertical lines in the 'crosshatch' pattern.
  By default, if unset, it uses 'pattern_fill' (#35).

• 'circle' pattern can now be adjusted by 'pattern_type' and 'pattern_subtype'. See help("grid.pattern_circle", package = "gridpattern") for more info.

• 'gradient' pattern can now use grid gradient feature introduced in R v4.1.0 if options(ggpattern_use_R4.1_gradients = TRUE).

• The following package options can now be set by options():

  • ggpattern_use_R4.1_clipping If TRUE use the grid clipping path feature introduced in R v4.1.0 else do a rasterGrob approximation of the clipped pattern.
  • ggpattern_use_R4.1_features If TRUE sets the default for all the other ggpattern_use_R4.1_* options arguments to TRUE.
  • ggpattern_use_R4.1_gradients If TRUE use the grid gradient feature introduced in R v4.1.0 else do a rasterGrob approximation of the gradient pattern.
  • ggpattern_use_R4.1_masks If TRUE use the grid mask feature introduced in R v4.1.0. Available for use in custom patterns.
  • ggpattern_use_R4.1_patterns If TRUE use the grid pattern feature introduced in R v4.1.0. Available for use in custom patterns.

Bug fixes and minor improvements

• 'pattern_alpha' default is now NA (preserve any alpha transparency in pattern_fill, pattern_fill2, and pattern_colour colors) rather than 1 (set them fully opaque).
• 'circle' pattern can now be adjusted by 'pattern_xoffset' and 'pattern_yoffset'.
