| -add
Value
| Specifies a signed value to add to every pixel. This option is
specific to X11R5.
|
| -frame
| This option indicates that the window manager frame should be included
when manually selecting a window.
|
| -display
Display
| Specifies the server connection.
|
| -help
| Prints the usage command syntax summary.
|
| -nobdrs
| Specifies that the window dump does not include the pixels that compose
the X window border. This is useful if you want to include the window
contents in a document as an illustration. The result of the
-nobdrs flag depends on which window manager is running.
Many window managers remove all borders from the client. For example,
the XGetWindowAttributes function returns the value of 0 for the
border_width field regardless of the border width when the client
was started. Therefore, any border that is visible on the screen
belongs to the window manager; the client has no knowledge of it.
In this case, the -nobdrs flag has no effect.
|
| -out
File
| Specifies the output file on the command line. The default is to
output to standard out.
|
| -root
| Indicates that the root window should be selected for the window dump,
without requiring the user to select a window with the pointer. This
option is specific to X11R5.
|
| -id id
| Indicates that the window with the specified resource id should be
selected for the window dump, without requiring the user to select a window
with the pointer. This option is specific to X11R5.
|
| -name
Name
| Indicates that the window with the specified WM_NAME property should be
selected for the window dump, without requiring the user to select a window
with the pointer. This option is specific to X11R5.
|
| -icmap
| Forces the first installed colormap of the screen to be used to obtain
RGB values. By default, the colormap of the chosen window is
used. This option is specific to X11R5.
|
| -screen
| Indicates that the GetImage request used to obtain the image should be
done on the root window, rather than directly on the specified window.
In this way, you can obtain pieces of the other windows that overlap the
specified window and, more importantly, capture menus or other popups that are
independent windows but appear over the specified window. This option
is specific to X11R5.
|
| -xy
| Selects xy format dumping instead of the default z format. This
option applies to color displays only.
