You will now see an alpha channel appear underneath the RGB color channels. The alpha
channel contains a grayscale version of the combined color channels in your graphic. Don't
forget to click on the alpha channel's 'eye' icon to make sure it is selected so it will be
included when the TGA file is saved.
5 Your selection has now been used to create the grayscale matte in the alpha channel.
If you want to, you can now go to the 'menu' bar and click 'select/deselect' to remove the
selection marquee.
6 Now it's time to save your TGA file.
Go to the file menu and click on 'save as'. Type the file name and select the location for
your file. In the format box, select 'targa', which is the full name for a TGA file and make sure
the 'alpha channels' checkbox is selected.
