font-family:Verdana'>If I create a Pixmap (XCreatePixmap) with a depth of 24
bits, the request to get the Geometry (XGetGeometry) of the created pixmap
returns it as 32. Ok, I can accept that. But if I then use the Pixmap in
a call to XRenderCreatePicture with a 32-bit ARGB Picture format, the call
fails. It seems that XRenderCreatePicture ‘knows’ that the
Pixmap is really 24 bits, as requested in the Pixmap creation, rather than 32
bits, as returned in the XGetGeometry call.<o:p></o:p></span></font></p>
