PostProcessingFilter
Interface for post-processing filters. These filters are applied to the rendered frame after the
rendering is complete, and before the frame is displayed on the screen. Color tinting and frame
blurring are examples of post-processing filters.

Method Summary
| Modifier and Type | Method and Description |

Method Detail

|---|---|---|---|---|---|---|
public void render(
int pass,
RenderingContext context,
RenderTarget renderedFrame
)Renders the frame for the current pass. On pass 0 the raw rendering output is given to the
function, and subsequent passes receive output from their predecessor. The rendering context
can be used to draw elements for the next pass (if there is one), or for the final output of
this filter. Note that the result of the final pass might still be processed by other
post-processing filters before actually being displayed on the screen. Parameters:

| setup | ||||
|---|---|---|---|---|
public boolean setup(
int pass,
FilterPassSetup setup
)Sets up the current rendering pass for this filter. A filter can process the render output in
several passes, and each pass will have access to the result of the previous. Pass 0 is where
the raw render output is given to the filter for processing. The frame setup for the previous
pass (or for the render output) is given to this function, which can be modified for the next
pass. Width and height specified for the next pass cannot exceed raw output dimensions. Parameters:
Returns:
A value indicating whether another pass is required to complete this filter (other
than the current pass that is being set up) |
