xwd -display :0.0 | convert - /tmp/root.gif

This requires ImageMagic to be installed. The cursor changes into a cross
and you can click on the window you want to capture.

For further features of xwd see man xwd.

I'm able to do this (using netpbm) but can I pipe to a clipboard area?

This is not Cygwin-specific, but you can capture any Windows window to
clipboard by pressing Alt-PrtSc.  To get an X window that way, you may
need to run X in multiwindow mode.  Just for the archives.

You can also write to /dev/clipboard from any Cygwin program to copy to
the Windows clipboard (or read from there to paste).  I'm not sure what
happens if you write an image there, though -- I think it's not set to the
right format.

/dev/clipboard is available but can not handle images.

I don't have /dev directory at all!!!!

I wasn't very clear, how do I copy this to WinXP's clipboard?

This is a virtual filesystem. You don't see the entry with ls /dev, but
it is there

 ls -l /dev/* /dev/null

 Either use alt-printscreen to capture the whole window or 
 use one of the solutions with xwd which create a file, open
 the file in a image processing program and copy it to clipboard.

 There is no other way.

Haisam,

/dev is a virtual directory in Cygwin (as Alexander already pointed out).
You may not see it in "ls /", but try "ls /dev/clipboard", and it'll be
there.  A while ago I posted a script to the cygwin list that would create
a real directory and files to allow listing and tab-completion in the
virtual one.  It seemed at the time that the script would soon become
obsolete (once Cygwin had true mkdev), but that's still some way off at
the moment.  So, I'm attaching a new version of this script.  Simply run
it, and then you'll be able to do "ls /dev" and see the device files.
HTH,
	Igor

RE: window image capture how

[Dawson, David W]

I realize that this is an *X-Free* ailing list, but it also is
a Cygwin list, and Cygwin is hosted on MS Windows, so...

Why not just use Alt-PrintScreen to copy the image to the "winxp
clipboard"
then paste into Paint, Word, or any other image/bitmap program to print?
