xsnap is a program that allows one to interactively take a "snapshot" of a region of the screen. This snapshot is then saved to a window. I've found it useful for such things as comparing a window's "before and after" pictures when debugging graphics code, and quicker than using xwd and xwud when there's no other reason to save a window to a file. However, it does eat up server memory, since it creates a pixmap for each snapshot. It also illustrates how one can have a user interactively specify a region of the screen or of a window using rubberbanding. The code for doing so is pretty self-contained and, if one is interested, it should be pretty easy to rip it out and use it in something else. As with all free code: no warranty, any shape, any color. -- Clauss Strauch internet: cbs@cad.cs.cmu.edu uucp: ...!harvard!cs.cmu.edu!cbs BITnet: cbs@cad.cs.cmu.edu%CMCCVMA
