<h2 style="text-align: left">CD_CLIPBOARD - Clipboard Driver (cdclipbd.h)</h2>

  <p>This driver allows the access to a Clipboard area. It is greatly dependent 
  on the system. In Win32, it creates an <a href="emf.html">Enhanced Metafile</a>, 
  a <b>Bitmap</b> or a <a href="mf.html">CD Metafile</a>; in X-Windows and with 
	GDK it 
  creates only a <a href="mf.html">CD Metafile</a>.</p>

<h3>Use</h3>

  <p>The canvas is created by means of a call to function <font face="Courier">
  <a href="../func/init.html#cdCreateCanvas">
  <strong>cdCreateCanvas</strong></a>(CD_CLIPBOARD, Data)</font>, after which 
  other functions in the CD library can be called as usual. The
  <font face="Courier">Data</font> parameter string is platform-dependent and 
  varies according to the metafile created. See each metafile's documentation, 
  but remember to exclude parameter <font face="Courier">&quot;filename&quot;.</font></p>
  <p>In the Windows environment, if the string &quot;<font face="Courier">-b</font>&quot; 
  is present at the end, it means that a <b>Bitmap</b> must be created instead of a 
  metafile, and, if the string <font face="Courier">&quot;-m&quot;</font> is 
	present at the end, a
  <b>CD Metafile</b> will be created. For a <b>Bitmap</b> the remaining string 
  must contains the bitmap size and optionally its resolution: <em>&quot;widthxheight [resolution] 
	-b&quot;</em> or in C &quot;<tt><em><strong>%dx%d %g -b&quot;</strong></em></tt>, 
  the resolution default is the screen resolution.</p>
  <p>In the X-Windows environment, the Display <font face="Courier">(&quot;%p&quot;)</font> 
  where the data will be stored must be passed as a parameter before the <b>CD 
  Metafile</b> parameters. This environment's driver is used only for 
  applications that use CD to communicate with each other, because only CD Metafiles 
  are created.</p>
  <p>Any amount of such canvases may exist simultaneously. It is important to 
  note that a call to function
  <a href="../func/init.html#cdKillCanvas">
  <font face="Courier"><strong>cdKillCanvas</strong></font></a> is required to 
  properly copy the data to the Clipboard.</p>
  <p>You can interpret the data from the Clipboard using function <strong>cdPlay</strong>. In the X-Windows environment, the 
  parameter <font face="Courier">&quot;data&quot;</font> for the <strong>cdPlay
  </strong>function is the pointer to the 
  Display where the metafile will be obtained. The <strong>cdRegisterCallback</strong> 
  must be called for the driver that will interpret the file, except for bitmaps 
  that the <strong>CD_CLIPBOARD</strong> driver must be used.</p>
<p>To use this driver in Windows using GDI+ is necessary to call 
<font face="Courier"><strong>
  cdUseContextPlus</strong></font><strong><font face="Courier">(1)</font></strong> 
before creating the canvas.</p>

<h3>Behavior of Functions</h3>

  <p>This driver is greatly platform-dependent. For further detail, see the <b>
  Behavior of Functions</b> in each platform: <a href="win32.html">Microsoft 
  Windows (GDI)</a>, <a href="xwin.html">X-Windows (XLIB)</a>. However, it 
  should be noted that some functions behave differently from the basic 
  functions of each platform.</p>
