Is there any inbuilt function in C by which one can directly read or access image?
No, C is a very simple language that does not understand the concept of images. You'll need to use a library to access the image; for example you can use the standard file library (fopen etc) if you're happy to handle the format yourself, if not you'll need to get an image manipulation library (if it's a JPG then you'll need a JPG image manipulation library for example).
I have attached the source code to read bmp from my Steganography project.
Hope it helps.
Musab, For security reasons we would not prefer the code as an attachment. Use the post to explain / post the code.
Actually i want to read each pixel of image, it may be of any type. For exa take .ppm image file, which contains less information. But i don`t know the exact structure of header or pixel. I am interested in C/C++ only. Plz tell me something about how to open image headers or pixels in C/C++? or tell me any sitename where i can found all information.
