## gogui-thumbnailer

gogui-thumbnailer — Create thumbnails for Go game files in SGF or Jago XML format.

## Synopsis

`gogui-thumbnailer` [`-config` `file`] [`-verbose`] [`-size` `n`] [`-scale`] `input.sgf` [`output.png`]

`gogui-thumbnailer` `-help`

`gogui-thumbnailer` `-version`

## Description

Create SGF thumbnails according to the Thumbnail Managing Standard from freedesktop.org. This allows the user to preview the SGF files in file managers that support this standard, like Nautilus. The installation script `install.sh` in the GoGui package will install this program as a thumbnailer for the GNOME desktop environment.

The thumbnails will show the final position of the main variation, or the first position that contains both black and white setup stones. The rationale for this is that one usually wants to see the last position of a game, which may contain black handicap setup stones before the moves, but the thumbnail should not show the solution of files containing Go problems.

If the thumbnailer is invoked without output filename, the thumbnails will be created in the directory `.thumbnails/normal` in the user home directory.
