Abstract
Some embodiments provide a method that provides an image display area that displays an image having a set of pixels that have pixel values in a color space. The method provides a first GUI item that activates a first sampling tool for selecting a first section of the image. The first section includes a first set of pixels for defining a first portion of the color space enclosing the pixel values of the first set. An image pixel whose pixel values are in the first portion is fully selected. The method provides a second GUI item that activates a second sampling tool for selecting a second section of the image displayed in the image display area. The second section includes a second set of pixels for defining a second portion of the color space enclosing the first portion and excluding the pixel values of the first set of pixels.
