## NAME
    [MIME::Decoder::Binary](https://www.chedong.com/phpMan.php/perldoc/MIME%3A%3ADecoder%3A%3ABinary/markdown) - perform no encoding/decoding

## SYNOPSIS
    A generic decoder object; see [MIME::Decoder](https://www.chedong.com/phpMan.php/perldoc/MIME%3A%3ADecoder/markdown) for usage.

## DESCRIPTION
    A [MIME::Decoder](https://www.chedong.com/phpMan.php/perldoc/MIME%3A%3ADecoder/markdown) subclass for the "binary" encoding (in other words, no encoding).

    The "binary" decoder is a special case, since it's ill-advised to read the input line-by-line:
    after all, an uncompressed image file might conceivably have loooooooooong stretches of bytes
    without a "\n" among them, and we don't want to risk blowing out our core. So, we read-and-write
    fixed-size chunks.

    Both the encoder and decoder do a simple pass-through of the data from input to output.
