Class javax.imageio.stream.ImageInputStream

Examples of javax.imageio.stream.ImageInputStream.readByte()

javax.imageio.stream.ImageInputStream.readByte()
Reads a byte from the stream and returns it as a byte value. Byte values between 0x00 and 0x7f represent integer values between 0 and 127. Values between 0x80 and 0xff represent negative values from -128 to /1.
The bit offset within the stream is reset to zero before the read occurs. @return a signed byte value from the stream. @exception java.io.EOFException if the end of the stream is reached. @exception IOException if an I/O error occurs.
