How do I read JPEG and PNG pixels in C++ on Linux?

Question

I\'m doing some image processing, and I\'d like to individually read each pixel value in a JPEG and PNG images.

In my deployment scenario, it would be awkward for me

Answer 1

There is no standard library in the C-standard to read the file-formats.

However, most programs, especially on the linux platform use the same library to decode the image-formats:

For jpeg it's libjpeg, for png it's libpng.

The chances that the libs are already installed is very high.
