STIFF 2.0 release

Posted by Emmanuel in releases, STIFF on February 1, 2010 – 16:09

STIFF V2.0 has been released! This version adds a wealth of new features:

complete rewriting of the conversion engine, now based on libTIFF 4.0
- BigTIFF support: manages arbitrary large images (64-bit system required),
- lossy or lossless on-the-fly image compression,
- 8 or 16-bit per component,
New tiled multiresolution pyramidal TIFF output mode to create giant zoomable pictures for the web. Check out these examples streamed through the IIPImage server software,
X,Y or XY image flipping options.
2-5× better performance than previous version on multi-core machines thanks to multithreaded conversion code and non-blocking calls to libTIFF. Sadly, the libTIFF library itself is not multithreaded,
Built-in power-law, sRGB and ITU-R BT rec.709 gamma corrections,
XML-VOTable metadata output, with user-friendly XSLT stylesheet provided.

More details can be found in the ChangeLog.

Excellent release. Please, what about the possibility to include comments line in the header or tail of the image with the astrometric solution of the image in a similar way as Aladin. When an Aladin image plane is save as jpg image, also it is saved the Aladin astrometric solution as comments in the header. This comments are keep if you convert (using convert command) from jpg to tif and viceversa. My idea is to use the stiff output (converted to jpg) as input in Aladin with astrometic coordinates. Thanks a lot.

Thanks rbarba. I wasn’t aware of this possibility in Aladin. I’ll check what I can do and implement it right away if it is straightforward.
