Constructor Detail

J2KReadState

public J2KReadState(javax.imageio.stream.ImageInputStream iis,
                    J2KImageReadParamJava param,
                    J2KMetadata metadata,
                    J2KImageReader reader)

Constructs J2KReadState.

Parameters:

iis - The input stream.

param - The reading parameters.

metadata - The J2KMetadata to cache the metadata read from the input stream.

reader - The J2KImageReader which holds this state. It is necessary for processing abortion.

Throws:

java.lang.IllegalArgumentException - If the provided iis, param or metadata is null.
