png++ for Mac

png++ is a C++ command-line tool that wraps the libpng library, allowing developers to read and write PNG images in their programs without having to deal directly with libpng's rather low-level C interface. It mainly addresses the problem of cumbersome and error-prone interfaces when handling PNG with C++, and is suited to developers who are already familiar with C++ and need to integrate PNG reading and writing capabilities into their projects, especially those who have image processing needs but do not want to introduce a large framework. As a command-line tool, it can also work with scripts to perform batch image conversion or inspection tasks. Its overall positioning is practical, aimed at developers willing to write their own code and with some understanding of low-level libraries, rather than ordinary users looking for graphics software they can use directly.
