51
52A lightweight object that interprets memory as a 2D array of pixels. Models <a class="el" href="g_i_l_0308.html" title="GIL&#39;s 2-dimensional view over immutable GIL pixels.">ImageViewConcept</a>,<a class="el" href="g_i_l_0344.html" title="Concept for all pixel-based GIL constructs, such as pixels, iterators, locators,...">PixelBasedConcept</a>,<a class="el" href="g_i_l_0290.html" title="Concept for iterators, locators and views that can define a type just like the given...">HasDynamicXStepTypeConcept</a>,<a class="el" href="g_i_l_0292.html" title="Concept for locators and views that can define a type just like the given locator...">HasDynamicYStepTypeConcept</a>,<a class="el" href="g_i_l_0294.html" title="Concept for locators and views that can define a type just like the given locator...">HasTransposedTypeConcept</a>.
53<p>
54Image view consists of a <a class="el" href="g_i_l_0599.html" title="Represents a pixel value (a container of channels). Models: HomogeneousColorBaseValueConcept...">pixel</a> 2D locator (defining the mechanism for navigating in 2D) and the <a class="el" href="g_i_l_0038.html" title="container interface over image view. Models ImageConcept, PixelBasedConcept">image</a> dimensions.<p>
55Image views to images are what ranges are to STL containers. They are lightweight objects, that don't own the pixels. It is the user's responsibility that the underlying data remains valid for the lifetime of the <a class="el" href="g_i_l_0038.html" title="container interface over image view. Models ImageConcept, PixelBasedConcept">image</a> view.<p>
56Similar to iterators and ranges, constness of views does not extend to constness of pixels. A const <code><a class="el" href="g_i_l_0040.html" title="A lightweight object that interprets memory as a 2D array of pixels. Models ImageViewConcept...">image_view</a></code> does not allow changing its location in memory (resizing, moving) but does not prevent one from changing the pixels. The latter requires an <a class="el" href="g_i_l_0038.html" title="container interface over image view. Models ImageConcept, PixelBasedConcept">image</a> view whose value_type is const.<p>
57Images have interfaces consistent with STL 1D random access containers, so they can be used directly in STL algorithms like: <div class="fragment"><pre class="fragment"> <a class="code" href="g_i_l_0214.html#g718772a47188f4e2ecfce2f28fa3dc4f" title="std::fill(I,I,V) with I being a iterator_from_2d">std::fill</a>(img.begin(), img.end(), red_pixel);
58</pre></div><p>
59In addition, horizontal, vertical and 2D random access iterators are provided.<p>
60Note also that <code><a class="el" href="g_i_l_0040.html" title="A lightweight object that interprets memory as a 2D array of pixels. Models ImageViewConcept...">image_view</a></code> does not require that its element type be a <a class="el" href="g_i_l_0599.html" title="Represents a pixel value (a container of channels). Models: HomogeneousColorBaseValueConcept...">pixel</a>. It could be instantiated with a locator whose <code>value_type</code> models only <code><a class="el" href="g_i_l_0376.html">Regular</a></code>. In this case the <a class="el" href="g_i_l_0038.html" title="container interface over image view. Models ImageConcept, PixelBasedConcept">image</a> view models the weaker <a class="el" href="g_i_l_0366.html" title="2-dimensional view over immutable values">RandomAccess2DImageViewConcept</a>, and does not model <a class="el" href="g_i_l_0344.html" title="Concept for all pixel-based GIL constructs, such as pixels, iterators, locators,...">PixelBasedConcept</a>. Many generic algorithms don't require the elements to be pixels. <table border="0" cellpadding="0" cellspacing="0">
