opening jpg file in C++

well , u can process an image file in photoshop , never heard about c++.......i think c++ opens codes (i.e. plain text) .

I wanted to open the jpg file and process with the information in my code. I wanted to perform the fft of an image. for that i have to open the image and get the data on an array and then i have to start getting the fft. hope u understand now.

Run ur compiler........
and drag the image file into the compiler.

I am reporting your reply to the moderators. It seems you dont know what is C++ from the way you answered and you are just replying with bogus replies.

Please reply usefully and only if you know.

Search for this header file in google: jpeglib.h
You can get it easily from the Independent Jpeg Group.
Check for the documentation on what decompression functions are available in the above said file.

hi lucky_star,

I have opened jpeg files before in C. I just dont remember them. And i dont recollect using any special headers for opening the files. Its just the parameters that i am not able to recollect while using the fopen function.

thks,
legolas.
