// This file conatins the C API of the common encoder/decoder part of libjpegli
// library, which is based on the C API of libjpeg, with the function names
// changed from jpeg_* to jpegli_*, while compressor and dempressor object
// definitions are included directly from jpeglib.h
//
// Applications can use the libjpegli library in one of the following ways:
//
// (1) Include jpegli/encode.h and/or jpegli/decode.h, update the function
// names of the API and link against libjpegli.
//
// (2) Leave the application code unchanged, but replace the libjpeg.so library
// with the one built by this project that is API- and ABI-compatible with
// libjpeg-turbo's version of libjpeg.so.
