SyntaxThe DownsampleFilter type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | DownsampleFilter |
Initializes a new instance of the DownsampleFilter class.
|
Methods| Name | Description | |
|---|---|---|
| Dispose |
Releases all resources used by an instance of the PostProcessor class.
(Inherited from PostProcessor.) |
 | Dispose(Boolean) |
Releases the unmanaged resources used by an instance of the PostProcessor class
and optionally releases the managed resources.
(Inherited from PostProcessor.) |
| Equals | (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnDisable |
Called when this post-processor is disabled.
(Inherited from PostProcessor.) |
| OnEnable |
Called when this post-processor is enabled.
(Inherited from PostProcessor.) |
| OnProcess |
Called when the post-processor should perform the post-processing.
(Overrides PostProcessorOnProcess(RenderContext).) |
| Process |
Performs the post-processing using the SourceTexture
and the RenderTarget specified in the render context.
(Inherited from PostProcessor.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Properties| Name | Description | |
|---|---|---|
 | DefaultTargetFormat |
Gets or sets the default target format.
(This property is used by the PostProcessorChain).
(Inherited from PostProcessor.) |
| Enabled |
Gets or sets a value indicating whether this post-processor is enabled.
(Inherited from PostProcessor.) |
| GraphicsService |
Gets the graphics service.
(Inherited from PostProcessor.) |
| IsDisposed |
Gets a value indicating whether this post-processor has been disposed of.
(Inherited from PostProcessor.) |
| Name |
Gets or sets the name of the post-processor.
(Inherited from PostProcessor.) |
RemarksThis post-processor reduces the resolution of the SourceTexture to match the target Viewport.
If this post-processor is used in a PostProcessorChain, you can use the property DefaultTargetFormat to specify the target resolution.
Render targets are downsampled by averaging samples. However, some render targets might require a different downsample function. The DownsampleFilter will check if the source texture is the depth buffer (GBuffer0), and when this is the case, it will perform a special downsampling.
