示例1: processAlgorithm
def processAlgorithm(self, parameters, context, feedback):
inputFile = self.parameterAsRasterLayer(parameters, self.INPUT, context).source()
zFactor = self.parameterAsDouble(parameters, self.Z_FACTOR, context)
outputFile = self.parameterAsOutputLayer(parameters, self.OUTPUT, context)
outputFormat = QgsRasterFileWriter.driverForExtension(os.path.splitext(outputFile)[1])
aspect = QgsAspectFilter(inputFile, outputFile, outputFormat)
aspect.setZFactor(zFactor)
aspect.processRaster(feedback)
return {self.OUTPUT: outputFile}示例2: processAlgorithm
def processAlgorithm(self, parameters, context, feedback):
inputFile = exportRasterLayer(self.parameterAsRasterLayer(parameters, self.INPUT_LAYER, context))
zFactor = self.parameterAsDouble(parameters, self.Z_FACTOR, context)
outputFile = self.parameterAsRasterOutputLayer(parameters, self.OUTPUT_LAYER, context)
outputFormat = raster.formatShortNameFromFileName(outputFile)
aspect = QgsAspectFilter(inputFile, outputFile, outputFormat)
aspect.setZFactor(zFactor)
aspect.processRaster(None)
return {self.OUTPUT_LAYER: outputFile}
