This is handy when -you want to cut, copy or just modify a part of the image without affecting -the rest. For processing selected objects &krita; applies a mask. Each pixel of -the selection is processed based on a value of its mask, or the <quote>level -of the selection</quote>, that can range from 0 (unselected) to 255 -(selected).
