</span>I am writing a GTK2 program that gets previews/screenshots of all open windows. My program scales the previews and puts them in GtkImages.<br>
<br>
CAIRO_FILTER_FAST gives rather low-quality results, but CAIRO_FILTER_GOOD is rather slow.<br>
<br>
I wanted to try scaling the previews using XRender in order to find out if it is any better or faster compared to Cairo scaling.<br></blockquote><div><br></div><div>Unfortunatly XRender is going to give the the exact same results as CAIRO_FILTER_FAST.<br><br> <br></div></div></div></div>
