qgis_variabledistancebuffer.Rd
QGIS Algorithm provided by QGIS Variable distance buffer (qgis:variabledistancebuffer). This algorithm computes a buffer area for all the features in an input layer. The size of the buffer for a given feature is defined by an attribute, so it allows different features to have different buffer sizes.

source
- Input layer. Path to a vector layer.
field
- Distance field. The name of an existing field. ; delimited list of existing field names.
number
- Segments. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
boolean
- Dissolve result. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
enum
of ("Round", "Flat", "Square")
- End cap style. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
enum
of ("Round", "Miter", "Bevel")
- Join style. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number
- Miter limit. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
sink
- Buffer. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm()

logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
.
logical specifying if messages from qgisprocess::qgis_run_algorithm()
should be printed (TRUE
) or not (FALSE
). Default value is FALSE
.
