Releases: tommyettinger/pngcs
Last Google Code release, 1.1.4
Note from @tommyettinger: I'm trying to bring over everything from pngcs' archived Google Code project, and the releases didn't automatically come over to GitHub. You most likely want pngcs_1_1_4_src.zip , since it includes docs as well as the sources and the two versions of binaries.
PngCs version 1.1.4
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
As of version 1.1.4, two assemblies are provided for different environments:
- 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
- .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
Licensing
The ICSharpCode.SharpZipLib.dll assembly, provided with this library,
must be referenced together with pngcs.dll by client projects using the .Net 2.0 version.
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. See LICENSE.txt , distributed
with this library.
