示例1: processAlgorithm
def processAlgorithm(self, progress):
inputFile = self.getParameterValue(self.INPUT_LAYER)
zFactor = self.getParameterValue(self.Z_FACTOR)
azimuth = self.getParameterValue(self.AZIMUTH)
vAngle = self.getParameterValue(self.V_ANGLE)
outputFile = self.getOutputValue(self.OUTPUT_LAYER)
outputFormat = raster.formatShortNameFromFileName(outputFile)
hillshade = QgsHillshadeFilter(inputFile, outputFile, outputFormat, azimuth, vAngle)
hillshade.setZFactor(zFactor)
hillshade.processRaster(None)示例2: processAlgorithm
def processAlgorithm(self, parameters, context, feedback):
inputFile = self.parameterAsRasterLayer(parameters, self.INPUT, context).source()
zFactor = self.parameterAsDouble(parameters, self.Z_FACTOR, context)
azimuth = self.parameterAsDouble(parameters, self.AZIMUTH, context)
vAngle = self.parameterAsDouble(parameters, self.V_ANGLE, context)
outputFile = self.parameterAsOutputLayer(parameters, self.OUTPUT, context)
outputFormat = QgsRasterFileWriter.driverForExtension(os.path.splitext(outputFile)[1])
hillshade = QgsHillshadeFilter(inputFile, outputFile, outputFormat, azimuth, vAngle)
hillshade.setZFactor(zFactor)
hillshade.processRaster(feedback)
return {self.OUTPUT: outputFile}
