<p>Hello, I'm not that experienced with cairo.</p>
<p><br>
</p>
<p>Currently I have a program that draws a background, and then draws some text over that background. The text moves around over the background. The image is redrawn often (multiple times a second).</p>
<p><br>
</p>
<p>The background is generated through cairo, it is not an image or something like that.</p>
<p><br>
</p>
<p>What is the most efficient way to accomplish this? I know that I could set the paint operator to source and redraw everything each frame, but it seems inefficient.</p>
<p>Is there a way to draw a layer, and then save that layer indefinitely (or have a layer dedicated to the text)? So that then I could just clear just the text each time and draw it in a new location?</p>
<p><br>
</p>
<p>I'm using Xlib and drawing to an window through cairo_xlib_surface_create().</p>
<p><br>
</p>
<p>Heres what I'm basically trying to do:</p>
<p><br>
</p>
<p><span style="font-family: "Courier New", monospace;"> if (firstrun) {</span></p>
<p><span style="font-family: "Courier New", monospace;"> </span><span style="font-family: "Courier New", monospace;">draw_background();</span></p>
<p><span style="font-family: "Courier New", monospace;"> }</span></p>
<p><br>
</p>
<p><span style="font-family: "Courier New", monospace;"> clear_text();</span></p>
<p><span style="font-family: "Courier New", monospace;"> draw_text(new_location);</span></p>
<p><br>
</p>
