Описание
Remove edges that are the background color from the image.
Список параметров
-
fuzz -
By default target must match a particular pixel color exactly. However, in many cases two colors may differ by a small amount. The fuzz member of image defines how much tolerance is acceptable to consider two colors as the same. This parameter represents the variation on the quantum range.
