11.6 GTK+

GTK+ is a potential source for some of the image libraries that Emacs requires. GTK+ is installed along with other ports of GUI software, such as the GIMP image editor, and Pidgin instant messenger client. If GTK+ is installed when you run addpm, Emacs will use the image libraries that it provides, even if they are not on the PATH. GTK+ ships with JPEG, PNG and TIFF support.
