If any other headers of MS Office is possible for U, please suggest me?

Thanking U

Please spell out your words and write clearly. Your question is almost impossible to understand.


A good description of JPEG headers can be found here:
http://www.obrador.com/essentialjpeg/headerinfo.htm

Lots of sample code for reading JPEG's can be found through Google, and lots of Linux programs (EOG, GQview, etc.), have source code you can look through.

Can you please describe your problem more clearly?

I am sorry for I have asked U a question is not understandable.
So i asked U for some Idea or little code for My college project.

My college project definition............

Q: Make a system using C language, such system can perform as follow

when we create any file on windows, by changing its extension,
unknown person who does not relate with that file can not know originally in which format that file is made.
So,by reading that file in program then that system check in which type that file is made originally.

Example as:
make file in type word ( .doc ) then change extension to access ( . mdb ).So that file now always open in access, But when we put that file in System(project) then that system can check the file originally of type word.

If possible then send me code or any website link. I wish to make this system in Java or C.....

Link by proj. guide :
fetch the every files' headers
Thanking U

Headers generally go along with libraries, unless they describe a binary struct that's at the beginning of the file (not sure if JPEG is like this; probably is.) Even so, there is a libjpeg, which would probably help.

i would call gdalinfo .But i have gdal installed

you could also use cimg.h ( google it )
and write a program

or if "vips" is installed you can call libvips and get the info
