Examples of javax.imageio.stream.ImageInputStream

javax.imageio.stream.ImageInputStream
A seekable input stream interface for use by ImageReaders. Various input sources, such as InputStreams and Files, as well as future fast I/O sources may be "wrapped" by a suitable implementation of this interface for use by the Image I/O API. @see ImageInputStreamImpl @see FileImageInputStream @see FileCacheImageInputStream @see MemoryCacheImageInputStream
