This tool will convert a shapefile containing polygons to a shapefile containing lines.
The following is an example of a Python script that uses this tool:
wd = pluginHost.getWorkingDirectory()
inputFile = wd + "input.shp"
outputFile = wd + "output.shp"
args = [inputFile, outputFile]
pluginHost.runPlugin("PolygonsToLines", args, False)
This is a Groovy script also using this tool:
def wd = pluginHost.getWorkingDirectory()
def inputFile = wd + "input.shp"
def outputFile = wd + "output.shp"
String[] args = [inputFile, outputFile]
pluginHost.runPlugin("PolygonsToLines", args, false)
