STAMP: A GNU image timestamp utility
-------------------------------------
The main difference between v2.0 and earlier versions is the
addition of a GTK front-end to stamp (gstamp), and removal
of most of the command-line options.
These options are now read from a configuration file, located
in ~/.stamprc. A sample of this file is provided in the
"doc" subdirectory, but will also be created for you during
the install process.
Here is essentially what you need to do to get a nice webcam
running using stamp:
1) Create a small script that achieves the following steps:
Generate an image using some video source (like a QuickCam)
Run stamp on this image
Optionally wait for a while
Repeat
A sample script, shown below (also provided in the doc/
subdirectory) is an example of one such script:
#!/bin/tcsh
loop:
cqcam -32- -a+ -j -q 75 > /tmp/webcam.jpg
stamp -f ;
sleep 40 ;
goto loop
stamp is called with -f so that the resulting image will be
sent using FTP to the server listed in the .stamprc file. Without
specifying -f, the information about FTP will be ignored from your
.stamprc file.
You can customize the output of stamp quite a bit my editing the
~/.stamprc file. Because stamp reads this file during each pass
of the loop in the above script, changes can be made to the appearance
of the JPEG produced by stamp, without killing and restarting your
webcam script. This is one of the main advantages of version > 2.0
of stamp.
The GTK graphical user interface allows you to manipulate all of
the options in .stamprc, and provides a preview of what the image
will look like, after being stamped. Remember, stamp and the GTK
interface are independent programs (for now).

We sincerely hope you enjoy the program. Please report problems to
