This package contains C software to implement JPEG image compression and decompression. JPEG (pronounced "jay-peg") is a standardized compression method for full-color and gray-scale images. JPEG is intended for compressing "real-world" scenes; line drawings, cartoons and other non-realistic images are not its strong suit. JPEG is lossy, meaning that the output image is not exactly identical to the input image. -- quoted from 3rdparty/libjpeg/README.
Qt optionally links against libjpeg to order to provide JPEG viewing and writing.
libjpeg is the work of Tom Lane, Philip Gladstone, Jim Boucher, Lee Crocker, Julian Minguillon, Luis Ortiz, George Phillips, Davide Rossi, Guido Vollbeding, Ge' Weijers, and other members of the Independent JPEG Group.
See 3rdparty/libjpeg/README for license details.
The libmng library supports decoding, displaying, encoding, and various other manipulations of the Multiple-image Network Graphics (MNG) format image files. It uses the zlib compression library, and optionally the JPEG library by the Independant JPEG Group (IJG) and/or lcms (little cms), a color-management library by Marti Maria Saguer. -- quoted from 3rdparty/libmng/doc/libmng.txt.
Qt optionally links against libmng to order to provide JPEG viewing and writing.
The primary copyright holder for libmng is Gerard Juyn (gerard@libmng.com), and it is distributed under a very free license.
See 3rdparty/libmng/LICENSE for license details.
Libpng was written as a companion to the PNG specification, as a way of reducing the amount of time and effort it takes to support the PNG file format in application programs. -- quoted from 3rdparty/libpng/libpng.txt.

The primary copyright holder for libpng is Glenn Randers-Pehrson, and it is distributed under a very free license.

zlib is a general purpose data compression library. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 -- quoted from 3rdparty/zlib/README.
Qt optionally links against libz to support libmng.
The primary copyright holders for zlib are Jean-loup Gailly and Mark Adler, and it is distributed under a very free license.
