%description
This pure Ruby library can read and write PNG images without depending on
an external
image library, like RMagick. It tries to be memory efficient and reasonably
fast.
It supports reading and writing all PNG variants that are defined in the
specification,
with one limitation: only 8-bit color depth is supported. It supports all
transparency,
interlacing and filtering options the PNG specifications allows. It can also
read and
write textual metadata from PNG files. Low-level read/write access to PNG
chunks is
also possible.
This library supports simple drawing on the image canvas and simple operations
like
alpha composition and cropping. Finally, it can import from and export to
RMagick for
interoperability.
Also, have a look at OilyPNG at http://github.com/wvanbergen/oily_png. OilyPNG
is a
drop in mixin module that implements some of the ChunkyPNG algorithms in C,
which
provides a massive speed boost to encoding and decoding.
