'Locates an image file of the name name.xpm, name.xbm or name.ppm
in one of the bitmap directories (see the addbitmapdir command
above). If more than one file with the same name (but different
extensions) exist, then the image type is chosen according to the
depth of the X display: xbm images are chosen on monochrome
displays and color images are chosen on color displays. By using
tix_ getimage, you can avoid hard coding the pathnames of the
image files in your application. When successful, this command
returns the name of the newly created image, which can be used to
configure the -image option of the Tk and Tix widgets.'
