If you attempt to + create a canvas in another platform, function <font face="Courier"><strong> + cdCreateCanvas</strong></font> will return NULL.</p> +<p><span style="color: #FF0000"><strong>It is recomended to use EMF instead of WMF whenever is possible.</strong></span> </p> + +<h3>Use</h3> + + <p>The canvas is created by means of a call to the function + <font face="Courier"> + <a href="../func/init.html#cdCreateCanvas"> + <strong>cdCreateCanvas</strong></a>(CD_WMF, Data)</font>, after which other + functions in the CD library can be called as usual.
