==== PNGCS : A small library to read/write huge PNG files in C# === PngCs is a C# to read/write PNG images. It provides a simple API for progressive (sequential line-oriented) reading and writing. It's specially suitable for huge images, which one does not want to load fully in memory. It supports all PNG spec color models and bitdepths: RGB8/RGB16/RGBA8/RGBA16, G8/4/2/1, GA8/4/2/1, PAL8/4/2/1, all filters/compressions settings. It does not support interlaced images. It also has support for Chunks (metadata). This is a port of the PngJ library (Java): http://code.google.com/p/pngj/ the API, documentation and samples from PNGJ apply also to this PngCs library: http://code.google.com/p/pngj/wiki/Overview The distribution of this library includes documentation in folder docs/ See also the included sample projects, -------------------------------------------------------------- NOTE: Since version 1.1.4 two assemblies are provided for different environments: 1 For .Net 4.5 : dotnet45/png45.dll This uses an internal Zlib implementation based on the new .Net 4.5 DeflateStream Advantages: Single dll, does not requires SharpZipLib dll Better speed 2 .Net 2.0 compatible: dotnet20/png.dll This requires an extra dll (included) ICSharpCode.SharpZipLib.dll Advantages: Works with old .net versions (2.0 and above) Slightly better compression ------------------------------------------------------------------------ The ICSharpCode.SharpZipLib.dll assembly, provided with this library, must be referenced together with pngcs.dll by client projects. Because SharpZipLib is released under the GPL license with an exception that allows to link it with independent modules, PNGCS relies on that exception and is released under the Apache license.
