NAME

       Tk::WinPhoto - Load a Photo image from a window

SYNOPSIS

	 use Tk;
	 use Tk::WinPhoto;

	 my $image = $mw->Photo(-format => 'Window', -data => oct($mw->id));
	 $image->write($path_name, -format => 'BMP|PPM|XPM');

DESCRIPTION

       This is an extension for Tk800.* which will load a Photo image from a snapshot of an X window specified by the -data option.

       The window must exist and be visible. Because the code allows you to capture windows not owned by Tk it does not attempt to enforce this.
       If you are capturing one of Tk's windows then use "$w->update".

       If window is mapped, but obscured by other windows then what is captured is the rectangle the window would occupy. This can be considered a
       feature.  For Tk-owned windows "$w->raise" can used to bring window forward.

       Once the Photo is loaded it can be saved using "$image->write(-format => ...)" using any of formats which support writing.

Name
       XUnmapWindow, XUnmapSubwindows - unmap windows

Syntax
       XUnmapWindow(display, w)
	  Display *display;
	  Window w;

       XUnmapSubwindows(display, w)
	  Display *display;
	  Window w;

Arguments
       display	 Specifies the connection to the X server.

       w	 Specifies the window.

Description
       The function unmaps the specified window and causes the X server to generate an event.  If the specified window is already unmapped, has no
       effect.	Normal exposure processing on formerly obscured windows is performed.  Any child window will no longer be visible until another
       map call is made on the parent.	In other words, the subwindows are still mapped but are not visible until the parent is mapped.  Unmapping
       a window will generate events on windows that were formerly obscured by it.

       can generate a error.

       The function unmaps all subwindows for the specified window in bottom-to-top stacking order.  It causes the X server to generate an event
       on each subwindow and events on formerly obscured windows.  Using this function is much more efficient than unmapping multiple windows one
       at a time because the server needs to perform much of the work only once, for all of the windows, rather than for each window.

       can generate a error.

Diagnostics
       A value for a Window argument does not name a defined Window.
