- xwpick, developed by Evgeni Chernyaev, allows a rectangular
image of a window to be captured and saved as PostScript, GIF,
PCX (IBM PC), PICT (Macintosh), PPM (PBMPlus). Note that the
generated PostScript code is more compact than other utilites of
this sort, so if file-size is an issue, then get this app.
