ShapefileDataSet.ClipSize Property
Gets or sets a value indicating that large features should be clipped into smaller pieces to improve reading performance.
Syntax
public System.Double ClipSize { get; set; }Property Value
Default: 0.0
The maximum size of a feature in meters; larger features are clipped.
This property can only be modified before the dataset has been initialized. Attempting to modify it after initialization will cause an exception to be thrown.
Remarks
The dataset can clip large features into smaller parts when the feature index is built. This can result in a significant performance gain for geodata that contains large polygons or lines. Setting this property to a value larger than 0.0 will activate feature clipping. The clip size is interpreted as the maximum extension of a polygon or line (in meters) along the x- and y-axis.
Note that the clipped parts will be returned by the dataset as separate features, although they will all have the same feature ID. Also note that with some types of visualization, the clipping might result in visual artifacts. For instance, if you outline polygons with a LineVisualizer, all clipped edges will also be outlined.
If a feature index already exists this property has no effect.
All clipping information is stored in the index file and no modification is done to the source data.
