<h1>surface_getpixel_ext</h1>
<p>With this function you can get the full <b>abgr 32bit</b> value of any pixel of a (previously created) surface.</p>
<p class="note"><b>NOTE</b>: This function will have a huge performance hit and so should only be used when absolutely necessary.</p>
<p> </p>
<h4>Syntax:</h4>
<p class="code">surface_getpixel_ext(surface_id, x, y);</p>
<table>
<tbody>
<tr>
<th>Argument</th>
<th>Description</th>
</tr>
<tr>
<td>surface_id</td>
<td>The ID of the surface to use.</td>
</tr>
<tr>
<td>x</td>
<td>The x coordinate of the pixel to check</td>
</tr>
<tr>
<td>y</td>
<td>The y coordinate of the pixel to check</td>
</tr>
</tbody>
</table>
<p> </p>
<h4>Returns:</h4>
<p class="code">Real</p>
<p> </p>
<h4>Example:</h4>
<p class="code">col = surface_getpixel_ext(mouse_x, mouse_y);<br/> alpha = (col >> 24) & 255;<br/> blue = (col >> 16) & 255;<br/> green = (col >> 8) & 255;<br/> red = col & 255;</p>
<p>The above code will get the 32bit colour value at the position of the mouse and then split it into its component values, storing them in variables.</p>
