Workaround
For code to work in all aspect ratios try the following code- // Assign the new envelope to be the map's envelopedouble dWHAspect = Convert.ToDouble(theMap.Width) / Convert.ToDouble(theMap.Height);double dWHExtent = envelope.Width / envelope.Height;if (dWHAspect > dWHExtent){ // make width wider double dCenterX = envelope.MinX + (envelope.MaxX - envelope.MinX) / 2; double dCenterY = envelope.MinY + (envelope.MaxY - envelope.MinY) / 2; double dHeight = envelope.MaxY - envelope.MinY; double dWidth = dHeight * dWHAspect; envelope = new Envelope(new Coordinate(dCenterX, dCenterY), dWidth, dHeight);}else{ // make height wider double dCenterX = envelope.MinX + (envelope.MaxX - envelope.MinX)/2; double dCenterY = envelope.MinY + (envelope.MaxY - envelope.MinY) / 2; double dWidth = envelope.MaxX - envelope.MinX; double dHeight = dWidth / dWHAspect; envelope = new Envelope(new Coordinate(dCenterX, dCenterY), dWidth, dHeight);}envelope.Resize(1.5);theMap.SetExtent(envelope);theMap.Invalidate();Schritte zur Reproduzierung
