Examples of jjil.core.Sequence.push()

jjil.core.Sequence.push()
Process an image by the pipeline. The image is pushed onto the beginning of the pipeline, and then each stage's output is passed to the next stage, until the end of the pipeline is reached. Overrides PipelineStage.push(Image). @param i the image to be pushed. @throws jjil.core.Error if the pipeline is empty.
