qgis_extractbinary: QGIS algorithm - Extract binary field

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Extract binary field

Description

QGIS Algorithm provided by QGIS (native c++) Extract binary field (native:extractbinary). This algorithm extracts contents from a binary field, saving them to individual files. This algorithm extracts contents from a binary field, saving them to individual files. Filenames can be generated using values taken from an attribute in the source table or based on a more complex expression.

Usage

qgis_extractbinary(
  INPUT = qgisprocess:::qgis_default_value(),
  FIELD = qgisprocess:::qgis_default_value(),
  FILENAME = qgisprocess:::qgis_default_value(),
  FOLDER = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
FIELD	field - Binary field. The name of an existing field. ; delimited list of existing field names.
FILENAME	expression - File name. A valid QGIS expression string, e.g "road_name" = 'MAIN RD'.
FOLDER	folderDestination - Destination folder. Path for an existing or new folder.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output	logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
