A project for HPC0 by Eric Scouten

This project was begun on 2/4/2013 and is anticipated to take 4 days. Actually took a pretty long time, due to the nature of having to continually do trial and error with mouse movements.

To create a shell-script program that automatically draws whatever it is programmed to.

In order to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:

• Basic understanding of shell script
• Understanding of Linux
• man xte
• man xpaint
• man xwit
• man xwininfo

Attempting to create a script that can draw a landscape or picture of some sort using xpaint and xte/xwit

xwit is an X window interface tool. By default when used with no arguments in an xterm it de-iconifies and raises the window. You can specify a different function to do, such as iconifying the window, and apply it to several windows whose name begins with one of the given strings, or a particular window id given, or the window id found in the environment variable WINDOWID (which is set by xterm for the program it runs).

xte is a program that generates fake input using the XTest extension, more reliable than xse.

xwininfo is a utility for displaying information about windows. Various information is displayed depending on which options are selected. If no options are chosen, -stats is assumed.

The user has the option of selecting the target window with the mouse (by clicking any mouse button in the desired window) or by specifying its window id on the command line with the -id option. Or instead of specifying the window by its id number, the -name option may be used to specify which window is desired by name. There is also a special -root option to quickly obtain information on the screen's root window.

Again, if there is associated code with the project, and you haven't already indicated how to run it, provide a sample run of your code:

pod01:~/mystuff$ ./autodrawtest

I learned that making an automated drawing, of anything, is very time consuming but yet very rewarding! I'll probably remember this for a long time.
