Remove raster polygon holes — wbt_remove_raster_polygon

Removes polygon holes, or 'donut-holes', from raster polygons.

Usage

wbt_remove_raster_polygon_holes(
  input,
  output,
  threshold = 3,
  use_diagonals = TRUE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input: Name of the input raster image file.
output: Name of the output raster file.
threshold: Maximum size of removed holes, in grid cells. Blank for no threshold, i.e. remove all holes.
use_diagonals: Use diagonal neighbours during clumping operation.
wd: Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode: Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters: Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only: Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
