最初にQgsGeometryを作成
[code]
points = []
point1=QgsPoint()
point1.setX(-31446.8)
point1.setY(-51366.4)
points.append(point1)
point2=QgsPoint()
point2.setX(-31446.8)
point2.setY(-50366.4)
points.append(point2)
point3=QgsPoint()
point3.setX(-30446.8)
point3.setY(-50366.4)
points.append(point3)
point4=QgsPoint()
point4.setX(-31446.8)
point4.setY(-51366.4)
points.append(point4)
line = QgsLineString()
line.setPoints(points)
poly = QgsPolygon()
poly.setExteriorRing(line)
geom = QgsGeometry(poly)
[/code]
QgsGeometryをWKTから作成する時は
[code]
geom = QgsGeometry.fromWkt(‘Polygon ((-31446.7999999999992724 -51366.40000000000145519, -31446.7999999999992724 -50366.40000000000145519, -30446.7999999999992724 -50366.40000000000145519, -31446.7999999999992724 -51366.40000000000145519))’)
[/code]
Featureを作成
[code]
features = []
feature = QgsFeature(l.fields())
feature.setAttribute(0, ‘HELLO100’)
feature.setAttribute(1, 2)
feature.setGeometry(geom)
features.append(feature)
iface.activeLayer().dataProvider().addFeatures(features)
iface.activeLayer().triggerRepaint()
[/code]
2019/01/15 修正
iface.activeLayer().addFeatures([feature])
を
iface.activeLayer().dataProvider().addFeatures(features)
に修正
