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:
If a file with the same name as the image, and .tfw extension exists, it is used to georeference the image
the content of this ASCII file must be:
Mxx
Myx
Mxy
Myy
Dx
Dy
The image coordinates are calculated as:
x'=Mxx*x+Mxy*y+Dx
y'=Myx*y+Myy*y+Dy
