What is it?

J2K-Codec is a software component, developed to facilitate JPEG2000 usage.
It can save you 12,000 lines of code, replacing them with a single line.

Who should be interested?

J2K-Codec should interest virtually any person involved in the development of a program that works with graphics one way or another.

What is JPEG2000?

JPEG2000 is a revolutionary image compression standard based on wavelet technology and is replacing the old JPEG format.

Advantages of the new standard:
 •  Better image quality at the same file size - see for yourself!
 •  25%–35% smaller file sizes at comparable image quality.
 •  Good image quality even at very high compression ratios, over 80:1.
 •  Lossless compression mode (identical to original image).
 •  Transparency (alpha channel) support.
 •  Easy way to get 1/4, 1/8, 1/16, etc., of the original image.

Why should I go with J2K-Codec?

1. It's easy.

J2K-Codec is probably the easiest JPEG2000 decoder to use. With the special 1-Call shortcut functions and C++ wrapper classes, you don't need to read 20+ pages and figure out mysterious function parameters to start using it. And if you think that something is still not very clear or easy in J2K-Codec – please let us know! We do want to provide the most convenient way of working with JPEG2000 images.

Can it be any easier? ;-)

2. It's fast.

J2K-Codec is much faster than the free software libraries such as JasPer and OpenJPEG (to give you some clue – up to 10 times faster!) and has the same or better speed as many other commercial decoders.

3. It's reliable.

We tried hard to achieve good code quality and eliminate as many bugs as possible. All exceptions raised inside J2K-Codec are intercepted in API functions, so it won't crash your application, but instead will exit gracefully with a proper error code.

4. It's usable :-)

Here are some J2K-Codec features:
 •  .j2k and .jp2 files support.
 •  Lossy or lossless compression.
 •  Particular resolution level decoding (even for tiled images).
 •  Alpha-channel support.
 •  Up to 16 bits per component.
 •  Multi-core CPUs support.
 •  File, memory, exe-file resource or any custom data sources.
 •  Static linking (purchasable add-on – buy now!).
 •  Video hardware support (ADV202, ADV212 and Matrox Morphis).
 •  Special video decoding speed boost mode.
 •  easyDecode() 1-call shortcuts.
 •  Selective tiles decoding.
 •  Region of Interest (ROI).
 •  GeoJP2 (embedded GeoTIFF) and other metadata extraction.
    See also our free metadata editor.
 •  SSE code optimizations.
 •  Lots of samples in C++, C#, VB.NET and other languages.
 •  Simple yet powerful API with C++ wrapper.

5. It's not unreasonably expensive.

J2K-Codec's has one of the lowest prices on the market for a commercial JPEG2000 decoder.

You'll get detailed and easy-to-read documentation, several samples in C++, C#, VB.NET and other languages, and a collection of test images. There are no royalty fees. You can use J2K-Codec in as many of your own projects as you want.

6. It has a demo version.

You do not need to buy something you haven't tried. In the case of J2K-Codec, you won't buy marketing department promises; you will buy the same real product you have already tried to use, because J2K-Codec has a fully functional demo version. You buy only after you see that it suits you, not before. If something isn't good for you – then you lose nothing, you just leave and start looking for another library :-)

OK, I am interested, what's next?

Download the demo version of J2K-Codec, please, and see if it suits your needs. You can also visit our More Info and Links sections for more information about J2K-Codec, JPEG2000 and related products.
