C++ library for simple image manipulations

Question

I'm currently using openCV for some image reading, filtering and resizing.

However, openCV support a whole other bunch of functionality and is much too big for my taste. I'm looking for something much smaller or more dedicated (.so should be a few measly 10Ks).

Any recommendation on other libraries or home-brew projects?

The list of classes and functions I use is:

cv::Mat
cv::filter2D
cv::Point
cv::Rect
cv::Size
cv::MinMaxLoc
cv::resize
cv::Size
cv::Split
cv::Vec3f

Answer 1

ImageMagick provides just about all of the above, some under different names, and as well as the command line program there are bindings for various languages including C++ with Magick++.

Answer 2

LibVips https://github.com/libvips/libvips

And leptonica http://www.leptonica.com/

Will have the functionaity you need. Not sure about their final size, though;.
