All of the following programs are classified as raster graphics editors EXCEPT:

The reason Inkscape is not classified as a raster graphics editor is because it is actually a vector graphics editor. Raster graphics editors, such as Adobe Photoshop, GIMP, and Corel Photo-Paint, work with images and graphics that are composed of a grid of pixels. They primarily focus on manipulating and editing the individual pixels, which can result in loss of quality when scaling or transforming the image. Inkscape, on the other hand, is a vector graphics editor that works with paths and curves, allowing for scalable graphics that retain their quality regardless of size or transformation.
