transform back to summary

transform	back to summary
public Point2D transform(Point2D p, Effect defaultInput) Overrides com.sun.scenario.effect.DelegateEffect.transform. Doc from com.sun.scenario.effect.Effect.transform. Transform the specified point `p` from the coordinate space of the primary content input to the coordinate space of the effect output. In essence, this method asks the question "Which output coordinate is most affected by the data at the specified coordinate in the primary source input?" The definition of which input represents the primary content input and how the coordinate space of that input compares to the coordinate space of the result varies from effect to effect. Note that some effects may have a reasonable definition of how to map source coordinates to destination coordinates, but not the reverse. In particular, effects which map source coordinates discontiguously into the result may have several output coordinates that are affected by a given input coordinate and may choose to return one of many equally valid answers, or an undefined result such as `NaN`, or some other anomalous value. Most effects perform simple transformations of the color of each pixel and so represent an identity transform and return the point unchanged. Parameters p:Point2D the point in the coordinate space of the primary content input to be transformed defaultInput:Effect the default input `Effect` to be used in all cases where a filter has a null input Returns:Point2D the transformed point in the coordinate space of the result Annotations @Override

Parameters

p:Point2D: the point in the coordinate space of the primary content input to be transformed

untransform	back to summary
public Point2D untransform(Point2D p, Effect defaultInput) Overrides com.sun.scenario.effect.DelegateEffect.untransform. Doc from com.sun.scenario.effect.Effect.untransform. Transform the specified point `p` from the coordinate space of the output of the effect into the coordinate space of the primary content input. In essence, this method asks the question "Which source coordinate contributes most to the definition of the output at the specified coordinate?" The definition of which input represents the primary content input and how the coordinate space of that input compares to the coordinate space of the result varies from effect to effect. Note that some effects may have a reasonable definition of how to map destination coordinates back to source coordinates, but not the reverse. In particular, effects which produce entirely synthetic results not based on any content input may not be able to give a meaningful result to this query and may return undefined coordinates such as `0`, `Infinity`, or `NaN`. Most effects perform simple transformations of the color of each pixel and so represent an identity transform and return the point unchanged. Parameters p:Point2D the point in the coordinate space of the result output to be transformed defaultInput:Effect the default input `Effect` to be used in all cases where a filter has a null input Returns:Point2D the untransformed point in the coordinate space of the primary content input Annotations @Override
