| ==What's new in Siril 0.9 alpha==
| |
| | |
| Siril 0.9 alpha is the new version (2013-2014) of Siril. It is a massive upgrade of the previous 0.8 version of 2006 ([http://sourceforge.net/projects/siril/ old website]). Many things have changed since then, including:
| |
| | |
| * new [[Siril#Who_is_behind_Siril.3F|development team]] and [[Siril|website]]
| |
| * 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 any film with AVI extension) and export
| |
| * better image sequence handling, with non-contiguous sequences, but still requiring file names to be postfixed by integers (like: image001.fit and not image001L.fit)
| |
| * 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, false colors
| |
| * manual translation as new registration method with two preview renderings of the current image with reference frame in transparency
| |
| * automatic translation as new registration method for deep-sky images, based on the FWHM analysis of one star instead of DFT, more suited for planetary images
| |
| * new commands available for the command line, see the list of [[Siril:Commands|available commands]]
| |
| * a star finding algorithm with [[Siril:PSF|PSF]] information
| |
| * new processing functions: unsharp mask, background extraction, green dominance removal, new method for background equalization, and two-way Fourier transform used to remove annoying patterns in images
| |
| * numerous bugs fixed and internal code refactoring for a better extensibility
