<div class="textblock">When opening a display window, you can choose the way the pixel values will be normalized before being displayed on the screen. Screen displays only support color values between [0,255], and someWhen displaying an image into the display window using CImgDisplay::display(), values of the image pixels can be eventually linearly normalized between [0,255] for visualization purposes. This may be useful for instance when displaying <code>CImg<double></code> images with pixel values between [0,1]. The normalization behavior depends on the value of <code>normalize</code> which can be either <code>0</code>,<code>1</code> or <code>2</code> :</p><ul>
<li><code>0</code> : No pixel normalization is performed when displaying an image. This is the fastest process, but you must be sure your displayed image have pixel values inside the range [0,255].</li>
<li><code>1</code> : Pixel value normalization is done for each new image display. Image pixels are not modified themselves, only displayed pixels are normalized.</li>
<li><code>2</code> : Pixel value normalization is done for the first image display, then the normalization parameters are kept and used for all the next image displays. </li>
