Class IIOInputStreamAdapter

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    class IIOInputStreamAdapter
extends java.io.InputStream
    IIOInputStreamAdapter

    Note: You should always wrap this stream in a BufferedInputStream. If not, performance may degrade significantly.

      • IIOInputStreamAdapter

        public IIOInputStreamAdapter​(javax.imageio.stream.ImageInputStream pInput)
        Creates an InputStream that reads from the given ImageInputStream. The input stream will read from the current stream position, until the end of the underlying stream.
        Parameters:
        pInput - the ImageInputStream to read from.

        public IIOInputStreamAdapter​(javax.imageio.stream.ImageInputStream pInput,
                             long pLength)
        Creates an InputStream that reads from the given ImageInputStream. The input stream will read from the current stream position, until at most pLength bytes has been read.
        Parameters:
        pInput - the ImageInputStream to read from.
        pLength - the length of the stream
