Performance: ChunkyPNG is reasonably fast for Ruby standards, by only using
integer math and a highly optimized saving routine.
@item Interoperability with RMagick.

ChunkyPNG is vulnerable to decompression bombs and can run out of memory when
loading a specifically crafted PNG file.  This is hard to fix in pure Ruby.
Deal with untrusted images in a separate process, e.g., by using @code{fork}
or a background processing library.")

fact is that most parsers are insensitive to indentation.  If, however, the
strings are to be used otherwise, be it for printing or testing, the extra
indentation will probably be an issue and hence this gem.")
