+Pure Python PNG Reader/Writer
+
+This Python module implements support for PNG images (see PNG
+specification at http://www.w3.org/TR/2003/REC-PNG-20031110/ ). It reads
+and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64
+bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB,
+RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped
+images (1/2/4/8 bit). Adam7 interlacing is supported for reading and
+writing. A number of optional chunks can be specified (when writing)
+and understood (when reading): ``tRNS``, ``bKGD``, ``gAMA``.
+
+For help, type ``import png; help(png)`` in your python interpreter.
+
+A good place to start is the :class:`Reader` and :class:`Writer` classes.
+
+Requires Python 2.3. Limited support is available for Python 2.2, but
+not everything works. Best with Python 2.4 and higher. Installation is
+trivial, but see the ``README.txt`` file (with the source distribution)
+for details.
+
+This file can also be used as a command-line utility to convert
+`Netpbm <http://netpbm.sourceforge.net/>`_ PNM files to PNG, and the reverse conversion from PNG to
+PNM. The interface is similar to that of the ``pnmtopng`` program from
+Netpbm. Type ``python png.py --help`` at the shell prompt
+for usage and a list of options.
+
+A note on spelling and terminology
+----------------------------------
+
+Generally British English spelling is used in the documentation. So
+that's "greyscale" and "colour". This not only matches the author's
+native language, it's also used by the PNG specification.
+
+The major colour models supported by PNG (and hence by PyPNG) are:
+greyscale, RGB, greyscale--alpha, RGB--alpha. These are sometimes
+referred to using the abbreviations: L, RGB, LA, RGBA. In this case
+each letter abbreviates a single channel: *L* is for Luminance or Luma or
+Lightness which is the channel used in greyscale images; *R*, *G*, *B* stand
+for Red, Green, Blue, the components of a colour image; *A* stands for
+Alpha, the opacity channel (used for transparency effects, but higher
+values are more opaque, so it makes sense to call it opacity).
+
+A note on formats
+-----------------
+
+When getting pixel data out of this module (reading) and presenting
+data to this module (writing) there are a number of ways the data could
+be represented as a Python value. Generally this module uses one of
+three formats called "flat row flat pixel", "boxed row flat pixel", and
+"boxed row boxed pixel". Basically the concern is whether each pixel
+and each row comes in its own little tuple (box), or not.
+
+Consider an image that is 3 pixels wide by 2 pixels high, and each pixel
+has RGB components:
+
+Boxed row flat pixel::
+
+ list([R,G,B, R,G,B, R,G,B],
+ [R,G,B, R,G,B, R,G,B])
+
+Each row appears as its own list, but the pixels are flattened so that
+three values for one pixel simply follow the three values for the previous
+pixel. This is the most common format used, because it provides a good
+compromise between space and convenience. PyPNG regards itself as
+at liberty to replace any sequence type with any sufficiently compatible
+other sequence type; in practice each row is an array (from the array
+module), and the outer list is sometimes an iterator rather than an
+explicit list (so that streaming is possible).
+
+Flat row flat pixel::
+
+ [R,G,B, R,G,B, R,G,B,
+ R,G,B, R,G,B, R,G,B]
+
+The entire image is one single giant sequence of colour values.
+Generally an array will be used (to save space), not a list.
+
+Boxed row boxed pixel::
+
+ list([ (R,G,B), (R,G,B), (R,G,B) ],
+ [ (R,G,B), (R,G,B), (R,G,B) ])
+
+Each row appears in its own list, but each pixel also appears in its own
+tuple. A serious memory burn in Python.
+
+In all cases the top row comes first, and for each row the pixels are
+ordered from left-to-right. Within a pixel the values appear in the
+order, R-G-B-A (or L-A for greyscale--alpha).
+
+There is a fourth format, mentioned because it is used internally,
+is close to what lies inside a PNG file itself, and has some support
+from the public API. This format is called packed. When packed,
+each row is a sequence of bytes (integers from 0 to 255), just as
+it is before PNG scanline filtering is applied. When the bit depth
+is 8 this is essentially the same as boxed row flat pixel; when the
+bit depth is less than 8, several pixels are packed into each byte;
+when the bit depth is 16 (the only value more than 8 that is supported
+by the PNG image format) each pixel value is decomposed into 2 bytes
+(and `packed` is a misnomer). This format is used by the
+:meth:`Writer.write_packed` method. It isn't usually a convenient
+format, but may be just right if the source data for the PNG image
+comes from something that uses a similar format (for example, 1-bit
+BMPs, or another PNG file).

+ Create a PNG encoder object.
+
+ Arguments:
+
+ width, height
+ Image size in pixels, as two separate arguments.
+ size
+ Image size (w,h) in pixels, as single argument.
+ greyscale
+ Input data is greyscale, not RGB.
+ alpha
+ Input data has alpha channel (RGBA or LA).
+ bitdepth
+ Bit depth: from 1 to 16.
+ palette
+ Create a palette for a colour mapped image (colour type 3).
+ transparent
+ Specify a transparent colour (create a ``tRNS`` chunk).
+ background
+ Specify a default background colour (create a ``bKGD`` chunk).
+ gamma
+ Specify a gamma value (create a ``gAMA`` chunk).
+ compression
+ zlib compression level: 0 (none) to 9 (more compressed); default: -1 or None.
+ interlace
+ Create an interlaced image.
+ chunk_limit
+ Write multiple ``IDAT`` chunks to save memory.
+
+ The image size (in pixels) can be specified either by using the
+ `width` and `height` arguments, or with the single `size`
+ argument. If `size` is used it should be a pair (*width*,
+ *height*).
+
+ `greyscale` and `alpha` are booleans that specify whether
+ an image is greyscale (or colour), and whether it has an
+ alpha channel (or not).
+
+ `bitdepth` specifies the bit depth of the source pixel values.
+ Each source pixel value must be an integer between 0 and
+ ``2**bitdepth-1``. For example, 8-bit images have values
+ between 0 and 255. PNG only stores images with bit depths of
+ 1,2,4,8, or 16. When `bitdepth` is not one of these values,
+ the next highest valid bit depth is selected, and an ``sBIT``
+ (significant bits) chunk is generated that specifies the original
+ precision of the source image. In this case the supplied pixel
+ values will be rescaled to fit the range of the selected bit depth.
+
+ The details of which bit depth / colour model combinations the
+ PNG file format supports directly, are somewhat arcane
+ (refer to the PNG specification for full details). Briefly:
+ "small" bit depths (1,2,4) are only allowed with greyscale and
+ colour mapped images; colour mapped images cannot have bit depth
+ 16.
+
+ For colour mapped images (in other words, when the `palette`
+ argument is specified) the `bitdepth` argument must match one of
+ the valid PNG bit depths: 1, 2, 4, or 8. (It is valid to have a
+ PNG image with a palette and an ``sBIT`` chunk, but the meaning
+ is slightly different; it would be awkward to press the
+ `bitdepth` argument into service for this.)
+
+ The `palette` option, when specified, causes a colour mapped image
+ to be created: the PNG colour type is set to 3; greyscale
+ must not be set; alpha must not be set; transparent must
+ not be set; the bit depth must be 1,2,4, or 8. When a colour
+ mapped image is created, the pixel values are palette indexes
+ and the `bitdepth` argument specifies the size of these indexes
+ (not the size of the colour values in the palette).
+
+ The palette argument value should be a sequence of 3- or
+ 4-tuples. 3-tuples specify RGB palette entries; 4-tuples
+ specify RGBA palette entries. If both 4-tuples and 3-tuples
+ appear in the sequence then all the 4-tuples must come
+ before all the 3-tuples. A ``PLTE`` chunk is created; if there
+ are 4-tuples then a ``tRNS`` chunk is created as well. The
+ ``PLTE`` chunk will contain all the RGB triples in the same
+ sequence; the ``tRNS`` chunk will contain the alpha channel for
+ all the 4-tuples, in the same sequence. Palette entries
+ are always 8-bit.
+
+ If specified, the `transparent` and `background` parameters must
+ be a tuple with three integer values for red, green, blue, or
+ a simple integer (or singleton tuple) for a greyscale image.
+
+ If specified, the `gamma` parameter must be a positive number
+ (generally, a float). A ``gAMA`` chunk will be created. Note that
+ this will not change the values of the pixels as they appear in
+ the PNG file, they are assumed to have already been converted
+ appropriately for the gamma specified.
+
+ The `compression` argument specifies the compression level to
+ be used by the ``zlib`` module. Values from 1 to 9 specify
+ compression, with 9 being "more compressed" (usually smaller
+ and slower, but it doesn't always work out that way). 0 means
+ no compression. -1 and ``None`` both mean that the default
+ level of compession will be picked by the ``zlib`` module
+ (which is generally acceptable).
+
+ If `interlace` is true then an interlaced image is created
+ (using PNG's so far only interace method, *Adam7*). This does not
+ affect how the pixels should be presented to the encoder, rather
+ it changes how they are arranged into the PNG file. On slow
+ connexions interlaced images can be partially decoded by the
+ browser to give a rough view of the image that is successively
+ refined as more image data appears.
+
+ .. note ::
+
+ Enabling the `interlace` option requires the entire image
+ to be processed in working memory.
+
+ `chunk_limit` is used to limit the amount of memory used whilst
+ compressing the image. In order to avoid using large amounts of
+ memory, multiple ``IDAT`` chunks may be created.

+def from_array(a, mode=None, info={}):
+ """Create a PNG :class:`Image` object from a 2- or 3-dimensional array.
+ One application of this function is easy PIL-style saving:
+ ``png.from_array(pixels, 'L').save('foo.png')``.
+
+ .. note :
+
+ The use of the term *3-dimensional* is for marketing purposes
+ only. It doesn't actually work. Please bear with us. Meanwhile
+ enjoy the complimentary snacks (on request) and please use a
+ 2-dimensional array.
+
+ Unless they are specified using the *info* parameter, the PNG's
+ height and width are taken from the array size. For a 3 dimensional
+ array the first axis is the height; the second axis is the width;
+ and the third axis is the channel number. Thus an RGB image that is
+ 16 pixels high and 8 wide will use an array that is 16x8x3. For 2
+ dimensional arrays the first axis is the height, but the second axis
+ is ``width*channels``, so an RGB image that is 16 pixels high and 8
+ wide will use a 2-dimensional array that is 16x24 (each row will be
+ 8*3==24 sample values).
+
+ *mode* is a string that specifies the image colour format in a
+ PIL-style mode. It can be:
+
+ ``'L'``
+ greyscale (1 channel)
+ ``'LA'``
+ greyscale with alpha (2 channel)
+ ``'RGB'``
+ colour image (3 channel)
+ ``'RGBA'``
+ colour image with alpha (4 channel)
+
+ The mode string can also specify the bit depth (overriding how this
+ function normally derives the bit depth, see below). Appending
+ ``';16'`` to the mode will cause the PNG to be 16 bits per channel;
+ any decimal from 1 to 16 can be used to specify the bit depth.
+
+ When a 2-dimensional array is used *mode* determines how many
+ channels the image has, and so allows the width to be derived from
+ the second array dimension.
+
+ The array is expected to be a ``numpy`` array, but it can be any
+ suitable Python sequence. For example, a list of lists can be used:
+ ``png.from_array([[0, 255, 0], [255, 0, 255]], 'L')``. The exact
+ rules are: ``len(a)`` gives the first dimension, height;
+ ``len(a[0])`` gives the second dimension; ``len(a[0][0])`` gives the
+ third dimension, unless an exception is raised in which case a
+ 2-dimensional array is assumed. It's slightly more complicated than
+ that because an iterator of rows can be used, and it all still
+ works. Using an iterator allows data to be streamed efficiently.
+
+ The bit depth of the PNG is normally taken from the array element's
+ datatype (but if *mode* specifies a bitdepth then that is used
+ instead). The array element's datatype is determined in a way which
+ is supposed to work both for ``numpy`` arrays and for Python
+ ``array.array`` objects. A 1 byte datatype will give a bit depth of
+ 8, a 2 byte datatype will give a bit depth of 16. If the datatype
+ does not have an implicit size, for example it is a plain Python
+ list of lists, as above, then a default of 8 is used.
+
+ The *info* parameter is a dictionary that can be used to specify
+ metadata (in the same style as the arguments to the
+ :class:``png.Writer`` class). For this function the keys that are
+ useful are:
+
+ height
+ overrides the height derived from the array dimensions and allows
+ *a* to be an iterable.
+ width
+ overrides the width derived from the array dimensions.
+ bitdepth
+ overrides the bit depth derived from the element datatype (but
+ must match *mode* if that also specifies a bit depth).
+
+ Generally anything specified in the
+ *info* dictionary will override any implicit choices that this
+ function would otherwise make, but must match any explicit ones.
+ For example, if the *info* dictionary has a ``greyscale`` key then
+ this must be true when mode is ``'L'`` or ``'LA'`` and false when
+ mode is ``'RGB'`` or ``'RGBA'``.
