QGIS Algorithm provided by QGIS (native c++) Line substring (native:linesubstring). Returns the substring of lines which fall between start and end distances. This algorithm returns the portion of a line (or curve) which falls between the specified start and end distances (measured from the beginning of the line). Z and M values are linearly interpolated from existing values. If a multipart geometry is encountered, only the first part is considered when calculating the substring.

source
- Input layer. Path to a vector layer.
distance
- Start distance. 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.
distance
- End distance. 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
- Substring. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()

logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
