libpng

Compare

  Analyzed 14 days ago

libpng is the official PNG reference library. It supports almost all PNG features, is extensible, and has been extensively tested for over 17 years. libpng is available as ANSI C source code and requires zlib 1.0.4 or later (1.2.3 or 1.1.4 recommended due to potential security vulnerabilities in ... [More] earlier versions). In addition to the main library sources, libpng includes the rpng, rpng2 and wpng demo programs, the pngminus demo program, a subset of Willem van Schaik's PngSuite test images, and Willem's VisualPng demo program. Configure, CMake, Visualc projects, and various makefiles are included for building libpng. Libpng is under the libpng license. [Less]

zlib

Compare

  Analyzed 12 days ago

zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression ... [More] method used in Unix compress(1) and in the GIF image format, the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression. [Less]
