C Image Processing Libraries

Hi,

Does anyone know of a C graphics library that'll allow me to read and alter the pixel values of image. I'd like one for bmp and jpeg image files.

Thanks

Does it have to be C or can you use C++? I haven't used it but the Boost libraries always seem to get praised, and they have a Generic Image Library which does quite a lot by the looks of it.

It's doesn't have to be but I'm a bit of a novice in C as it is so I don't how i'll cope with C++ libraries however i'll have a look at that one. Thanks

Could try asking on the C boards -

In that case GIL might be the way to go. If you click on the tutorial from the link I posted earlier it looks like it gives you all the information you need to set it up and a nice example too:

GIL consists of header files only and does not require any libraries to link against. It does not require Boost to be built. Including boost/gil/gil_all.hpp will be sufficient for most projects.

Pretty simple to set-up

OpenCV is good - used it for my dissertation.

CImg. As with GIL, it's C++ and header-only.

might be overkill depending on what you want to do but, TinaVision

Currently using OpenCV for a project. It's been pretty reliable so far for us
