At the lower left side of the indow, you have the trial-zone. This contains a few sliders and buttons. Letﾕs try to explain a bit more. The two sliders are used to define the wanted part of the image. They are zero-based, which means the top-left icon has coordinates 0,0. To see the icons, select the right one using the sliders, and then click on the Try It button. If you would like to just export that one icon, wlick on Save This, and a window will appear providing you with a choice where to save that icon. It will get a blank name (which in fact is 10 invisible characters long).
