Since the original ofxOpenCv addon bundled to OpenFrameworks doesn't support some basic stuff (cv::imread, cv::imwrite with .png or .jpg export), here I placed modified version of static libralies.
Simply you can download a library file to replace the one in ofxOpenCv, by using wget command or downloading the whole repo by saving as zip option.
OpenFrameworks project uses Apothecary to compile third-party libraries to be used along with the library. You can clone the repository to compile opencv library again for your platform. The libraries here are compiled for x86_64 arch since OF 0.11.0 supports 64bit system.
You can use opencv.sh to compile the same library by yourself. Placing it under apothecary/apothecary/formulas/opencv to compile opencv.
- upload libraries for different platforms rather than osx (windows, RasPi, iOS...)
