<h2>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 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">"filename".</font></p>
<p>In the Windows environment, if the string "<font face="Courier">-b</font>"
is present, it means that a <b>Bitmap</b> must be created instead of a
metafile, and, if the string <font face="Courier">"-m"</font> is specified, 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>"-b
widthxheight [resolution]"</em> or in C "<tt><em><strong>%dx%d %g"</strong></em></tt>,
the resolution default is the screen resolution.</p>
<p>In the X-Windows environment, the Display <font face="Courier">("%p")</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">"data"</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>
