The problem is that we currently do not allow any choices. The cairo driver is explicitly starting with a non-transparent white background. It is not as clear to me exactly what the Qt driver is doing when it starts a new page, though I don't believe that the driver itself sets the background to be white. -Hazen ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
