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> :<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></ul><!DOCTYPE html PUBLIC "-//w3c//dtd html 4.0 transitional//en"><html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>The CImg Library - C++ Template Image Processing Library</title> <meta content="David Tschumperle" name="author"> <link rel="shortcut icon" type="image/x-icon" href="http://cimg.sourceforge.net/favicon.ico" /> <link rel="icon" type="image/png" href="favicon.png" /> <link href="doxygen.css" rel="stylesheet" type="text/css"> </head> <body bgcolor="#ffffff" fgcolor="#000000" alink="#ff0000" link="#0000ee" vlink="#551a8b"> <hr noshade="noshade" size="1" width="100%"> <a href="http://sourceforge.net"> <img src="http://sourceforge.net/sflogo.php?group_id=96492&type=3" border="0" height="37" width="125"></a><!-- Start of StatCounter Code --><script type="text/javascript" language="javascript"><!-- var sc_project=895001; var sc_invisible=1; var sc_partition=7; var sc_security="5ea85181"; //--></script><script type="text/javascript" language="javascript" src="http://www.statcounter.com/counter/counter.js"></script><noscript><a href="http://www.statcounter.com/" target="_blank"><img src="http://c8.statcounter.com/counter.php?sc_project=895001&java=0&security=5ea85181&invisible=1" alt="counter stats" border="0"></a> </noscript><!-- End of StatCounter Code --> </body></html>?? 快捷鍵說明
