<p class=MsoNormal><font size=2 face=Verdana><span style='font-size:10.0pt;
font-family:Verdana'>Is there any X operation (maybe through X Render) for
color key overlays? I want to overlay a pixmap onto another using a color of
the overlay (say RGB=0) to indicate transparency to the second pixmap. I have
been able to use the alpha channel of the overlay to achieve this, where the
overlay is a 32 bit pixmap, but I’m constrained in one situation to use a
24 bit pixmap with no alpha information. (I guess a related question is whether
there is an efficient way to generate a 32 bit pixmap from a 24 bit pixmap
where alpha is created from the contents of the 24 bit).<o:p></o:p></span></font></p>
