<h1>draw_surface_ext</h1>
<p>This function will draw the given surface as in the function <a href="draw_surface.htm"><tt>draw_surface()</tt></a> but with additional options to change the scale, blending, rotation and alpha of the surface being drawn. Changing these values does
<i>not</i> modify the resource in any way (only how it is drawn).</p>
<p class="note"><b></b><b>NOTE</b>: When working with surfaces there is the possibility that they can cease to exist at any time due to them being stored in texture memory. You should <b>ALWAYS</b> check that a surface exists using <span style="font-size:1px;"><a href="surface_exists.htm"><tt style="font-size: 14px">surface_exists()</tt></a></span> before referencing them directly.</p>
<p> </p>
