Double buffering allows Renderers to redraw without incurring the cost of a complete map redraw. Renderers on a double buffered map cannot interact with labels.

Namespace:  Telogis.GeoBase
Assembly:  geobase.net (in geobase.net.dll) Version: 4.99.0.0
Syntax
Copy
public bool DoubleBuffering { get; set; }

Property Value

Type: Boolean
Remarks

Double buffering only affects maps that have not changed zoom, size or center when a Renderer is added.

When double buffering is off (false), a Renderer added to a map may cause the labelling to be redrawn around the Renderer, allowing the Renderer to reserve space for itself and resulting in nicer looking maps where labels are not partially obscured by Renderers.

When double buffering is on (true), a Renderer added to a map is simply drawn over the previously rendered image of the map. This is faster but can result in clutter caused by partially obscured labels.
