<h1>surface_getpixel</h1>
<p>This function can be used to get the colour of a specific pixel from a surface, using the local coordinates of the surface where (0,0) is the top left corner. This function should <i>not</i> be used very often as it is extremely slow and may cause a
pause in your game.</p>
<p class="note"><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>
