示例1: ZoomToLayerEnvelope
private void ZoomToLayerEnvelope(IEnvelope layerEnvelope)
{
if (_extendBuffer)
{
layerEnvelope.ExpandBy(layerEnvelope.Width, layerEnvelope.Height);
}
const double eps = 1e-7;
if (layerEnvelope.Width > eps && layerEnvelope.Height > eps)
{
layerEnvelope.ExpandBy(layerEnvelope.Width / 10, layerEnvelope.Height / 10); // work item #84
}
else
{
double zoomInFactor = 0.05; //fixed zoom-in by 10% - 5% on each side
double newExtentWidth = ViewExtents.Width * zoomInFactor;
double newExtentHeight = ViewExtents.Height * zoomInFactor;
layerEnvelope.ExpandBy(newExtentWidth, newExtentHeight);
}
ViewExtents = layerEnvelope.ToExtent();
}示例2: AddMargin
/// <summary>
/// Expands the given boundingBox by percentage.
/// </summary>
/// <param name="boundingBox">Boundingbox to expand</param>
/// <param name="percentage">Percentage by which boundingBox is expanded</param>
