Application Notes

We have found some things that are very useful while working as a team on the EE 552 project.

• The X-view software allows us to capture any image or window from our UNIX workstation screen and save the image under any popular image format such as bmp, gif, ps and jpeg.

Grabbing an Image from UNIX

1. Run UNIX as usual and setup the display you want.

2. In an xterm window on your LOCAL machine, type

xv &

3. Move the resulting window so it is not entirely overlapping the window you want to capture (drag with the right mouse button).

4. Bring your window to the front (use the left mouse button in its title bar), then move the cursor over part of the xv window and type control-G (for "grab image").

5. Now move the cursor back to the target window and press the center button (to capture the entire target window) or press and drag the left button (to capture a portion of the target window). A beep/double-beep indicates the capture.

6. Return the cursor to the xv window and type control-S (hold down the control key and type S, for "save file"). A dialog box will come up. Make sure GIF (or any format of your choice) and FULL color are selected. Type a file name for your stored image, and return (or click OK).

7. Other notes:

• You can use the center mouse button in the title bar of the xv window to quit xv.
• You can check your image at any time by typing

xv filename &

• You can also crop the image or edit in xv by pressing the right mouse button to bring up the xv controls dialog box.
• You can zoom out by factors of two by holding down the control key while pressing the left mouse, use right button to zoom out.
