Menu: View->Background image
GiD allows an image to be used as a background for visualization purposes (the supported image formats are gif, png, jpeg, tiff, bmp, tga and ppm). There are the following options:
- Fit screen: an image will be shown in GiD's background window; it will be modified if necessary so that it fills the graphical window correctly.
