Grab

Grab is an application that can capture screen shots of Mac OS X and its applications. You tell Grab to capture what appears on your screen and it creates a TIFF file. You can then view the TIFF file with Preview or any application capable of opening TIFFs.

Tips

    You might find screen shots useful for documenting softwareor for writing books like this one.

    Although Grab is a handy screen shot utility, it isn't the best available for Mac OS X. Snapz Pro X, a shareware program from Ambrosia Software, is far better. If you take a lot of screen shots, be sure to check it out at www.ambrosiasw.com.

To create a screen shot

Set up the screen so it shows what you want to capture.

2.

Open the Grab icon in the Utilities folder (Figure 1 ).

If Grab is already running, click its icon on the Dock (Figure 68 ) to make it active.
