Siril 0.9 alpha

The alpha version is the name of the version currently being developed. It is not released as a fixed package. It can be obtained from the subversion repository linked in the main page. The first release will be 0.9 beta.


This version is developed and tested on Linux Mint 15, Debian 7 and Arch Linux. See the installation page for help on dependencies and compilation.

What's new in Siril 0.9 alpha

Siril 0.9 alpha is the new version (2013-2014) of Siril, a massive upgrade of the previous 0.8 version of 2006 (old website). Many things have changed since 0.8, including:

  • many new image formats supported for import (converted to Siril's FITS: 8-bit and 16-bit BMP, TIFF, JPEG, PNG, NetPBM binary images, RAW DSLR images and loaded natively: SER files) and export
  • better image sequence handling, with non-contiguous sequences, but still requiring file names to be numbered with integers
  • new graphical user interface based on GTK+ version 3.4 and above, and in general update of dependencies to latest versions
  • new display modes added to the standard linear scaling with lo/hi bounds: log, asinh, sqr, sqrt, histeq, negative
  • new manual translation method with two preview renderings of the current image with reference frame in transparency
  • new commands available for the command line, see the list of available commands
  • a star finding algorithm with PSF information
  • numerous bugs fixed and internal code refactoring for a better extensibility
