Method Summary

Modifier and Type	Method and Description
ImageData	filterImageDatas(FilterContext fctx, BaseTransform transform, Rectangle outputClip, T rstate, ImageData... inputs) Convenience method that sends the given input data through the current peer, and then attempts to release the input image data.
Effect.AccelType	getAccelType(FilterContext fctx) Returns one of the AccelType values, indicating whether this Effect is accelerated in hardware for the given FilterContext.
Effect	getInput() Returns the input for this Effect.
float	getLevel() Returns the level value, which controls the intensity of the sepia effect.
RenderState	getRenderState(FilterContext fctx, BaseTransform transform, Rectangle outputClip, Object renderHelper, Effect defaultInput) Returns the object representing the rendering strategy and state for the filter operation characterized by the specified arguments.
boolean	reducesOpaquePixels() Whether an opacity for any pixel is different (lower) than the corresponding pixel in the default input.
void	setInput(Effect input) Sets the input for this Effect to a specific Effect or to the default input if input is null.

Constructor Detail

SepiaTone

public SepiaTone()

Constructs a new SepiaTone effect with the default level value (1.0), using the default input for source data. This is a shorthand equivalent to:

     new SepiaTone(DefaultInput)
 

SepiaTone

public SepiaTone(Effect input)

Constructs a new SepiaTone effect with the default level value (1.0).

Parameters:

input - the single input Effect

Method Detail

getInput

public final Effect getInput()

Returns the input for this Effect.

Returns:

the input for this Effect

setInput

public void setInput(Effect input)

Sets the input for this Effect to a specific Effect or to the default input if input is null.

Parameters:

input - the input for this Effect

getLevel

public float getLevel()

Returns the level value, which controls the intensity of the sepia effect.

Returns:

the level value

setLevel

public void setLevel(float level)

Sets the level value, which controls the intensity of the sepia effect.

       Min: 0.0
       Max: 1.0
   Default: 1.0
  Identity: 0.0
 

Parameters:

level - the level value

Throws:

IllegalArgumentException - if level is outside the allowable range

getRenderState

public RenderState getRenderState(FilterContext fctx,
                                  BaseTransform transform,
                                  Rectangle outputClip,
                                  Object renderHelper,
                                  Effect defaultInput)

Description copied from class: FilterEffect

Returns the object representing the rendering strategy and state for the filter operation characterized by the specified arguments. This call can also be used to get a state object for non-rendering cases like querying the bounds of an operation in which case the FilterContext object may be null. outputClip and renderHelper may always be null just as they may be null for a given filter operation.

Specified by:

getRenderState in class FilterEffect<RenderState>

Parameters:

fctx - the context object that would be used by the Renderer if this call is preparing for a render operation, or null

transform - the transform for the output of this operation

outputClip - the clip rectangle that may restrict this operation, or null

renderHelper - the rendering helper object that can be used to shortcut this operation under certain conditions, or null

defaultInput - the Effect to be used in place of any null inputs

Returns:

reducesOpaquePixels

public boolean reducesOpaquePixels()

Description copied from class: Effect

Whether an opacity for any pixel is different (lower) than the corresponding pixel in the default input. It is always safe to return true from this method, though the consequences may be that the caller chooses to not utilize a planned optimization.

Specified by:

reducesOpaquePixels in class Effect

Returns:

true if this effect may reduce opacity of some pixels of one of it's input (and thus the default input) or it's relevant input(s) might have reduced opaque pixels of the default input already.

filterImageDatas

public ImageData filterImageDatas(FilterContext fctx,
                                  BaseTransform transform,
                                  Rectangle outputClip,
                                  T rstate,
                                  ImageData... inputs)

Convenience method that sends the given input data through the current peer, and then attempts to release the input image data.

Specified by:

filterImageDatas in class FilterEffect<T extends RenderState>

getAccelType

public Effect.AccelType getAccelType(FilterContext fctx)

Description copied from class: Effect

Returns one of the AccelType values, indicating whether this Effect is accelerated in hardware for the given FilterContext.

Specified by:

getAccelType in class Effect

Returns:

one of the AccelType values
