*FvwmBacker: RetainPixmap
Causes FvwmBacker to retain and publish the Pixmap with which
the background has been set. This works only for the -solid or
colorset commands. This is useful for applications which want to
use the root Pixmap on the background to simulate transparency
(for example, Eterm and Aterm use this method). This option
should also be used for the RootTransparent colorset option (see
the FvwmTheme man page). Note: with a colorset background this
command may add a lot of memory to the X server. For example,
this adds the pixmap width times height bytes with a TiledPixmap
image, screen_width times screen_height bytes with a Pixmap
image or a C,B,D,R,S or Y Gradient and screen_width bytes with a
VGradient or screen height bytes with an HGradient.
Note后面的东西尤其莫名其妙。
请教诸位了,谢谢。 |
