Python clip_by_extent Beispiele

Beispiel #1

    def test_clip_raster(self):
        """Test we can clip a raster layer."""
        layer = load_test_raster_layer('gisv4', 'hazard', 'earthquake.asc')
        expected = QgsRectangle(106.75, -6.2, 106.80, -6.1)
        new_layer = clip_by_extent(layer, expected)

        extent = new_layer.extent()
        self.assertAlmostEqual(expected.xMinimum(), extent.xMinimum(), 0)
        self.assertAlmostEqual(expected.xMaximum(), extent.xMaximum(), 0)
        self.assertAlmostEqual(expected.yMinimum(), extent.yMinimum(), 0)
        self.assertAlmostEqual(expected.yMaximum(), extent.yMaximum(), 0)
