This tab sets options related to capturing button controls, such as OK or CANCEL on dialog boxes or other program interface components.
You can select if the captured area should be enlarged beyond the button's edges by the specified number of pixels on each side of the button. This can make the capture look a bit better when pasted into a document, giving you a little "breathing room" around the button graphic.
If you enter negative values, the area will be decreased instead of enlarged.
For example, to capture Internet Explorer 6 buttons together with a 1 pixel black frame surrounding them, set each of the Left, Right, Top and Bottom values to 1 pixel.
You may change all four values by 1 pixel up or down by clicking the [+] and [-] buttons in the middle of the group, or you can reset all values to zero in order to start over by clicking the Reset button.
