It is used for offscreen drawings.</p> + +<h3>Use</h3> + + <p>The canvas is created by means of a call to function + <a href="../func/init.html#cdCreateCanvas"> + <font face="Courier"><strong>cdCreateCanvas</strong></font></a><font face="Courier">(CD_IMAGE, + Data)</font>, after which other functions in the CD library can be called as + usual. The function creates a CD canvas based on an existing Server Image. The + <font face="Courier">Data</font> parameter must be a pointer to an image + created with function + <a href="../func/server.html#cdCreateImage"> + <font face="Courier"><strong>cdCreateImage</strong></font></a>.</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 <b>end</b> the driver. You can call function + <a href="../func/server.html#cdKillImage"> + <font face="Courier"><strong>cdKillImage</strong></font></a> only after + calling <font face="Courier"><strong>cdKillCanvas</strong></font>.</p> + <p>For use with CDLUA, the Server Image passed as parameter must have been + created with function <strong><font face="Courier">cd.CreateImage</font></strong> + in Lua.</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="gdiplus.html">Windows Using GDI+</a>, + <a href="xwin.html">X-Windows (XLIB)</a>.
