Working with images in C++ or C

Question

The first thing is that I am a beginner. Okay?

I\'ve read related answers and questions, but please help me with this problem:

How can I open an JPEG image file

Answer 1

There are many good libraries for working with images in C and C++, none of which is clearly superior to all others. OpenCV^{wiki, project page} has great support for some of these tasks, while ImageMagick^{wiki, project page} is good at others. The JPEG group has its own implementation of JPEG processing functions as well. These are probably good resources to start from; the API documentation can guide you more specifically on how to use each of these.

As for whether C or C++ libraries are bound to be faster, there's no clear winner between the two. After all, you can always compile a C library in C++. That said, C++ libraries tend to be a bit trickier to pick up because of the language complexity, but much easier to use once you've gotten a good feel for the language. (I am a bit biased toward C++, so be sure to consider the source). I'd recommend going with whatever language you find easier for the task; neither is a bad choice here, especially if performance is important.

Best of luck with your project!
