Piecewise contrast stretch

Description

Performs a piecewise contrast stretch on an input image.

Usage

wbt_piecewise_contrast_stretch(
  input,
  output,
  FUN = "",
  greytones = 1024,
  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 image file.
FUN	Piecewise break-points e.g. '(50, 0.1); (150, 0.8); (255; 1.0).
greytones	Number of greytones in the output image.
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
