RenderTargetUsage Enumeration

XNA Game Studio 4.0

Determines how render target data is used once a new render target is set.

Namespace: Microsoft.Xna.Framework.Graphics
Assembly: Microsoft.Xna.Framework.Graphics (in microsoft.xna.framework.graphics.dll)

public enum RenderTargetUsage

	Member name	Description
	DiscardContents	Always clears the render target data.
	PlatformContents	Either clears or keeps the data, depending on the current platform. On Xbox 360, the render target will discard contents. On PC, the render target will discard if multisampling is enabled, and preserve the contents if not.
	PreserveContents	Always keeps the render target data.
