  79 <p>The Generic Image Library is designed with the following five goals in mind:</p>
  80 <div class="section" id="generality">
  81 <h2><a class="toc-backref" href="#id1">Generality</a></h2>
  82 <p>Abstracts image representations from algorithms on images.
  83 It allows for writing code once and have it work for any image type.</p>
  84 </div>
  85 <div class="section" id="performance">
  86 <h2><a class="toc-backref" href="#id2">Performance</a></h2>
  87 <p>Speed has been instrumental to the design of the library.
  88 The generic algorithms provided in the library are in many cases comparable
  89 in speed to hand-coding the algorithm for a specific image type.</p>
  90 </div>
  91 <div class="section" id="flexibility">
  92 <h2><a class="toc-backref" href="#id3">Flexibility</a></h2>
  93 <p>Compile-type parameter resolution results in faster code, but severely limits
  94 code flexibility. The library allows for any image parameter to be specified
  95 at run time, at a minor performance cost.</p>
  96 </div>
  97 <div class="section" id="extensibility">
  98 <h2><a class="toc-backref" href="#id4">Extensibility</a></h2>
  99 <p>Virtually every construct in GIL can be extended - new channel types,
 100 color spaces, layouts, iterators, locators, image views and images
 101 can be provided by modeling the corresponding GIL concepts.</p>
 102 </div>
 103 <div class="section" id="compatibility">
 104 <h2><a class="toc-backref" href="#id5">Compatibility</a></h2>
 105 <p>The library is designed as an STL complement.
 106 Generic STL algorithms can be used for pixel manipulation, and they are
 107 specifically targeted for optimization. The library works with existing
 108 raw pixel data from another image library.</p>
