[mapguide-users] creating georeferenced world file[jgw file]

[sanjay pandey]

Dear Sir/Madam

I am new to programming open source mapguide[One Month].I have started to
like it and catching it really fast.But presently i have stuck with a
problem which i think can be solved with your kind support.
The scenario is this that i want to generate the georeferenced image of the
current view of the map.I have successfully generated the jpg file of the
current map view now I want to generate a .jgw file also of the generated
image. I know that to generate to world file[.jgw file] i need to know
information of the below mentioned six line:

Line 1: A, pixel size in the x-direction in map units/pixel 
Line 2: D: rotation about y-axis 
Line 3: B: rotation about x-axis 
Line 4: E: pixel size in the y-direction in map units, almost always
negative
Line 5: C: x-coordinate of the center of the upper left pixel 
Line 6: F: y-coordinate of the center of the upper left pixel 

I can generate all the values except Line 1 and Line 4. It would be very
helpful if you could help me out with this. Also if you can provide me with
a small working example code.[I am doing allmy development . net].

Waiting for your quick reply and help.

Thanks & Regards
Sanjay Pandey
