Field Detail

target

protected volatile BufferedImage target

The image target as a result of processing. Note if processor is not provided then it will use source(java.io.InputStream) directly as the target

processor

protected PROCESSOR extends Img.Processor<PROCESSOR,STAGE> processor

The processor that apply a certain logic on source and generates the target

compressionQuality

protected float compressionQuality

Define the compression quality of the target image

Constructor Detail

ProcessorStage

public ProcessorStage(Lang.Func0<BufferedImage> source,
                      PROCESSOR processor)

Construct a ProcessorBuilder with an image source provider

Parameters:

source - the function that provides the image source

ProcessorStage

public ProcessorStage(BufferedImage source,
                      PROCESSOR processor)

Construct a ProcessorBuilder with image source specified

Parameters:

source - the image source to be processed

Method Detail

get

public BufferedImage get()

Returns the the target image as a result of processing or source image if no processor is provided

Overrides:

get in class Img._Load<STAGE extends Img.ProcessorStage<STAGE,PROCESSOR>>

Returns:

the target image

source

public STAGE source(InputStream is)

source

public STAGE source(BufferedImage source)

pipeline

public Img._Load pipeline()
