Inline functions. To follow or participate in the development of dlib subscribe to dlib on github. Also be sure to read the how to contribute page if you intend to submit code to the project.
To quickly get started using dlib, follow these instructions to build dlib. Major Features Documentation Unlike a lot of open source projects, this one provides complete and precise documentation for every class and function.
There are also debugging modes that check the documented preconditions for functions. When this is enabled it will catch the vast majority of bugs caused by calling functions incorrectly or using objects in an incorrect manner. Lots of example programs are provided I consider the documentation to be the most important part of the library. So if you find anything that isn't documented, isn't clear, or has out of date documentation, tell me and I will fix it.
High Quality Portable Code Good unit test coverage. The ratio of unit test lines of code to library lines of code is about 1 to 4. No other packages are required to use the library. There is no installation or configure step needed before you can use the library.
