I'd like to do some work with the nitty-gritties of computer imaging. I'm looking for a way to read single pixels of data, analyze them programatically, and change them. What is the best language to use for this (Python, c++, Java...)? What is the best fileformat?

I don't want any super fancy software/APIs... I'm looking for the bare basics.

If you need speed (you'll probably always want speed with image processing) you definitely have to work with raw pixel data. Java has some real disadvantages as you cannot access memory directly which makes pixel access quite slow compared to accessing the memory directly. C++ is definitely the language of choice for production use image processing. But you can, for example, also use C# as it allows for unsafe code in specific areas. (Take a look at the scan0 pointer property of the bitmapdata class.) I've used C# successfully for image processing applications and they are definitely much faster than their java counterparts. I would not use any scripting language or java for such a purpose.
