.. _PCD-PIL:

PCD-PIL Kodak PhotoCD
=====================

Extensions: ``.pcd``

*From the Pillow docs:*


PIL reads PhotoCD files containing ``RGB`` data. This only reads the 768x512
resolution image from the file. Higher resolutions are encoded in a proprietary
encoding.

Parameters for reading
----------------------

pilmode : str
    From the Pillow documentation:

    * 'L' (8-bit pixels, grayscale)
    * 'P' (8-bit pixels, mapped to any other mode using a color palette)
    * 'RGB' (3x8-bit pixels, true color)
    * 'RGBA' (4x8-bit pixels, true color with transparency mask)
    * 'CMYK' (4x8-bit pixels, color separation)
    * 'YCbCr' (3x8-bit pixels, color video format)
    * 'I' (32-bit signed integer pixels)
    * 'F' (32-bit floating point pixels)

    PIL also provides limited support for a few special modes, including
    'LA' ('L' with alpha), 'RGBX' (true color with padding) and 'RGBa'
    (true color with premultiplied alpha).

    When translating a color image to grayscale (mode 'L', 'I' or 'F'),
    the library uses the ITU-R 601-2 luma transform::

        L = R * 299/1000 + G * 587/1000 + B * 114/1000
as_gray : bool
    If True, the image is converted using mode 'F'. When `mode` is
    not None and `as_gray` is True, the image is first converted
    according to `mode`, and the result is then "flattened" using
    mode 'F'.
