public class JAITransformer
extends AbstractTransformer
implements ProvenanceSupporter

Applies an JAI transformation to the incoming image and outputs the generated image(s).

Input/output:
- accepts:
java.awt.image.BufferedImage
- generates:
java.awt.image.BufferedImage

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: JAITransformer
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-transformer <adams.data.jai.transformer.AbstractJAITransformer> (property: transformAlgorithm)
    The transformer to use for transformering the image.
    default: adams.data.jai.transformer.PassThrough
