A new version of the XISF specification document (eight public draft) is now available online:
http://pixinsight.com/doc/docs/XISF-1.0-spec/XISF-1.0-spec.html
You may need to refresh your browser.
The previous draft 7.1 document is also available for reference:
http://pixinsight.com/doc/docs/XISF-1.0-spec-D7.1/XISF-1.0-spec.html
As always, the entire PIDoc source code of the latest version is available on our GitHub open source repositories:
https://github.com/PixInsight/XISF-specification
Main changes:
- Lots of error corrections and bug fixes everywhere.
- Section 10.5 XISF Data Block Compression (http://pixinsight.com/doc/docs/XISF-1.0-spec/XISF-1.0-spec.html#__XISF_Data_Block_:_XISF_Data_Block_Compression__) has been completely rewritten to include subblock compression, the byte shuffling algorithm, and the LZ4/LZ4_HC compression codecs.
Hopefully this is the last draft document before the final XISF 1.0 specification.
All comments, suggestions and error reports are extremely welcome.
