Arguments

INPUT	source - Shapes. Path to a vector layer.
FIELD	field - Attribute. The name of an existing field. ; delimited list of existing field names.
OUTPUT	enum of ⁠("(0) data / no-data", "(1) index number", "(2) attribute")⁠ - Output Values. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
MULTIPLE	enum of ⁠("(0) first", "(1) last", "(2) minimum", "(3) maximum", "(4) mean")⁠ - Method for Multiple Values. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
LINE_TYPE	enum of ⁠("(0) thin", "(1) thick")⁠ - Lines. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
POLY_TYPE	enum of ⁠("(0) node", "(1) cell")⁠ - Polygon. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
GRID_TYPE	enum of ⁠("(0) 1 bit", "(1) 1 byte unsigned integer", "(2) 1 byte signed integer", "(3) 2 byte unsigned integer", "(4) 2 byte signed integer", "(5) 4 byte unsigned integer", "(6) 4 byte signed integer", "(7) 4 byte floating point", "(8) 8 byte floating point", "(9) same as attribute")⁠ - Data Type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX	extent - Output extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used.. Original algorithm parameter name: TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX.

...	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.
