LibTiff.Net is ready for you


I’m pleased to announce that we’ve completed LibTiff.Net. It is free and open source version (port) of classic LibTiff written using C#.

License is practically the same as for LibTiff. API is very close to original one. Code is fully managed.

LibTiff.Net was developed with a goal to produce images that are byte-to-byte equal to images produced by LibTiff-3.9.4.

You can download binaries or source code with tests here:

Differences (mostly renames of function names and types) between

LibTiff.Net and LibTiff-3.9.4 are described here.

Following codecs are implemented:

LZW, Packbits, Jpeg (using our own LibJpeg.Net), all CCITT versions, Deflate, Adobe Deflate

I hope you will find LibTiff.Net useful. Please write us if you have any questions or find any bugs.

LibJpeg.Net is at final stage of development


Today I want to share a good news with all of you: LibJpeg.Net is almost ready for release!

We started this free (as in speech and in beer) and open source project several months ago because we needed managed Jpeg library for our Docotic project. Docotic is a .NET library for reading and writing PDF files, so ability to handle images is essential to it.

We tried to find Jpeg library with quality comparable to quality of LibJpeg but without success. Sure, there are some .NET wrappers for LibJpeg, but no pure managed implementations. So, we started to implement our own 🙂

And now this work is almost done! We’ll announce when LibJpeg.Net will be available for download (and it’s source code too) in this blog, but you can also write us a letter and we’ll notify you by e-mail.
