<p>Represents a pixel value (a container of channels). Models: <a class="el" href="structboost_1_1gil_1_1_homogeneous_color_base_value_concept.html" title="Homogeneous color base that also has a default constructor.

<p>A pixel is a set of channels defining the color at a given point in an image. Conceptually, a pixel is little more than a color base whose elements model <code><a class="el" href="structboost_1_1gil_1_1_channel_concept.html" title="A channel is the building block of a color. Color is defined as a mixture of primary colors and a cha...">ChannelConcept</a></code>. The class <code>pixel</code> defines a simple, homogeneous pixel value. It is used to store the value of a color. The built-in C++ references to <code>pixel</code>, <code>pixel&amp;</code> and <code>const</code> <code>pixel&amp;</code> are used to represent a reference to a pixel inside an interleaved image view (a view in which all channels are together in memory). Similarly, built-in pointer types <code>pixel*</code> and <code>const</code> <code>pixel*</code> are used as the standard iterator over a row of interleaved homogeneous pixels.</p>
<p>Since <code>pixel</code> inherits the properties of color base, assigning, equality comparison and copy-construcion are allowed between compatible pixels. This means that an 8-bit RGB pixel may be assigned to an 8-bit BGR pixel, or to an 8-bit planar reference. The channels are properly paired semantically.</p>
<p>The single-channel (grayscale) instantiation of the class pixel, (i.e. <code>pixel&lt;T,gray_layout_t&gt;</code>) is also convertible to/from a channel value. This allows grayscale pixels to be used in simpler expressions like *gray_pix1 = *gray_pix2 instead of more complicated at_c&lt;0&gt;(gray_pix1) = at_c&lt;0&gt;(gray_pix2) or get_color&lt;gray_color_t&gt;(gray_pix1) = get_color&lt;gray_color_t&gt;(gray_pix2)</p>
