Пакет xwd: Информация

Xwd is an X Window System window dumping utility.  Xwd allows  X  users
to  store  window images in a specially formatted dump file.  This file
can then be read by various other X utilities for redisplay,  printing,
editing, formatting, archiving, image processing, etc.  The target win-
dow is selected by clicking the pointer in  the  desired  window.   The
keyboard  bell is rung once at the beginning of the dump and twice when
the dump is completed.
