    <br/> <!-- FIXME: should be in CSS -->
    <strong>babl is a dynamic, any to any, pixel format translation library</strong>.
    <br/>
    </p>
    
    <p>It allows converting between different methods of storing <a href='http://en.wikipedia.org/wiki/Pixel'>pixels</a> known as <em>pixel formats</em> that have
    with different bitdepths and other data representations, color models and
    component permutations.</p>
      
    <p> A vocabulary to formulate new <em>pixel formats</em> from existing
    primitives is provided as well as the framework to add new color models and
    data types.
    </p>



    <!--<a name='Background'></a>
    <h2>Background</h2>
    <p> When creating various libraries and small tools that deal with
    computer graphics I have often created functions for converting
    raster images between different representations.
    </p>

    <p>Libraries to help with such conversions already do exist, but no
    extendable candidates have surfaced in my searches.
    </p>

    <p>The vocabulary developed in babl will most likely be part of
    <a href='http://www.gegl.org/'>GEGL</a>'s vocabulary to describe image
    buffers.
    </p>-->

      <li>Fast.</li>
      <li>Accurate.</li>
      <li>Stable, small API.</li>
      <li>Self profiling and optimizing.</li>
      <li>ANSI C, works on win32, linux and mac, 32bit and 64bit systems.</li>

    <p><a href='http://www.gegl.org/'>GEGL</a> through <a
    href='http://www.gegl.org/api.html#GeglBuffer'>GeglBuffer</a> provides
    tiled buffers with on disk storage as well as linear buffers with accessor
    functions for efficient data access transparently using babl fishes for
    translation to the desired pixel formats.</p>

    <p>Babl uses git. The main repository is hosted by GNOME.
    It can be <a href='http://git.gnome.org/cgit/babl'>browsed online</a> and cloned with:

    <p>The following is a list of the major changes that have gone into
    each babl release. If there are significant improvements to babl when
    a GEGL release is done a babl release is most often put out just prior
    to the GEGL release.</p>

    <h2>Documentation</h2>
    <p>When using BablFishes to do your conversions, you request a fish to
    convert between two formats, and an optimal fish to babls capability is
    provided that you can use to do your conversions. Babl also provides
    the capability to describe new formats based on a vocabulary of user
    registered color models and data types.
    </p>

    <p>Babl provides a base vocabulary in BablBase and some extensions
    that are thought to be generally useful.</p>

    <p>When performing further extensions to the vocabulary of babl, the
    internal consistency is governed by reference conversions that operate
    on <em>double</em> (64 bit floating point values). The only color model
    created during BablCore bootstrap is <em>RGBA</em> (linear light RGB,
    0.0 - 1.0, with a linear 0.0 - 1.0 opacity channel) backed by the
    <em>double</em> datatype. Defined similarily to <a
    href='http://en.wikipedia.org/wiki/ScRGB_color_space'>scRGB</a> using
    64bit floating point.
    </p>

    <p>If babls conversion isn't fast enough, you can provide
    your own conversion shortcut between two formats. The registered
    shortcut might also be used by babl as an intermediate conversion when
    constructing BablFishes for other conversions.
    </p>

    <p>Babl extensions are shared objects. If you have already developed
    some fast conversion functions, wrapping them as babl extensions should
    not take much time and will speed up babl for other users as well.
    </p>

        <p>The processing operation that babl performs is copying including

        <p>If the environment variable <tt>BABL_STATS</tt> is set  containting
        a html pixel format conversion usage matrix will be written to
        <tt>/tmp/babl-stats.html</tt>. This allows figuring out which
        conversions is taking up time during processing, and what shortcuts <a
            href='#Extending'>extensions</a> might be created or improved to
        make babl do it's job faster.
        </p>

    <p>Through the environment variable <tt>BABL_TOLERANCE</tt> you can control
    a speed/performance trade off that by default is set very low (0.000001)
    values in the range 0.01-0.1 can provide reasonable preview performance
    by allowing lower numerical accuracy</p>.

        <h2>Color Management</h2>
        <p> Babl is not a color management system, since it doesn't deal with
        ICC profiles. Babl is designed primarily for internal use when the
        color space is already known (sRGB, CIE Lab, Luminance or similar).</p>

        <p>
        It is also possible to register new color models that are managed by a
        color management system like <em>lcms</em>, take a look at the <em>lcms-lab</em>
        extensions for an example.</p>

<h2>TODO</h2>
        
<ul>
  <li>Support for conversions between formats that have higher dimensionality than RGBA. (arbitrary meaningless components)</li>
  <li>Support for datatypes that are not a multiple of 8bit.</li>
  <li>dithering</li>
  <li>dynamic data attached to format, or internal handling of icc through
  a registered set of profiles</li>
  <li>
  Stocastic runtime profiling with running average of the peformance for
  conversions, to avoid problems incurred if other cpu intense is happening
  when babl tests a conversions. </li>
