Sozi 15.05 is available for testers and translators

Translations: Fran├žais

A new presentation editor has been under development since the beginning of 2014. Development went at a slow pace and only an early prototype was officially announced in October 2014. In 2015, it was followed by a long series of fixes and improvements. Several users started to use it daily, found issues and helped me fix them.

Sozi 15.05 is the latest in this series. I believe it is the right time to release it officially so that more people can try it, translate it, package it and report issues left unnoticed.

What's new in Sozi 15?

Until version 13.11, the editor for Sozi was provided as an Inkscape extension. The extension system of Inkscape had not been designed for this kind of use, so Sozi was not well integrated in Inkscape and the overall user experience was poor. Moreover, the editor depended on several other frameworks and libraries (Python 2.7, GTK2, PyGTK) that needed to be manually installed in Windows and OS X. Some of them are now deprecated. For all these reasons, Sozi has been almost completely rewritten with the following concerns:

A new user interface

Frames are created and modified using three panes:

It is no longer required to draw rectangles to delimit frames but it can help in some cases. Tutorials on this topic will be published soon.

The editor saves the presentation automatically each time the window loses focus and before quitting. If you modify the SVG document while Sozi is running, it will be reloaded automatically when Sozi gets the focus again. If saving and reloading do not happen automatically, you can still use the Save and Reload buttons.

A new file format

If you have used earlier versions of Sozi, you will notice that the new editor stores the presentation in separate files along your SVG document. For instance, if your original SVG document is my_presentation.svg, Sozi 15 will create two files:

Technically, the HTML file contains a copy of your SVG document, a copy of the presentation data, and the Sozi player software. It is a standalone document: if you want to share a presentation, you do not need to give the SVG and JSON files.

Sozi 15 can import presentations made with Sozi 13.

Known issues

The current version of the new editor does not display linked images. SVG documents that contain embedded images are displayed correctly but they can be slower to load if they contain a lot of big images.

Sozi 15 can be run either as a standalone desktop application, or as a hosted web application.
