Calculates the perimeters of polygons or classes within a raster image.

Usage

wbt_raster_perimeter(
  input,
  output = NULL,
  out_text = FALSE,
  units = "grid cells",
  zero_back = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input: Input raster file path. See wbt_file_path() for details.
output: Output raster file.
out_text: Would you like to output polygon areas to text?.
units: Area units; options include 'grid cells' and 'map units'.
zero_back: Flag indicating whether zero values should be treated as a background.
