Zero is a perfectly nice number!  There's nothing wrong with 0.0 in your world file, especially in the second and third lines.  For the vast majority of raster images you will find that the fourth line is the same as the first line with the sign reversed, and the second and third lines are 0.0.  A world file will often look like:
 
100.0
0.0
0.0
-100.0
12345.67
987654.32

 Hi
     I am trying to include a .tif file for raster background. For that i have to write a .tfw(world file) for the corresponding .tif file. The information that i need to put in the world file are X, Y Pixel size, rotational co-efficient and X, Y location of the center of the top left pixel. I am trying to find these values by using gdalinfo-- but some values are 0.0
in their corresponding field.
   Can anyone plz help me, how to get/set these values for the world file so that i can
keep my raster data georeferenced with other layers in my mapfile.
 
Thanks in advance
