PowerLine is a graphical software tool that allows you to produce SVG slide presentations, as well as SVG images, or SVG posters. The graphical user interface looks similar to Microsoft Powerpoint. You use drag and drop to put text, lists, and geometrical shapes on a slide. You can also add math formulas in Latex, which are then rendered as path elements in the original Latex math font. This is why no external fonts or LaTex installation is required.
Slides are automatically saved. If you want, you can export the slides also as TEX, HTML or TIKZ files.
To view a PowerLine presentation, you do not need PowerLine installed on your computer. You just need a browser — Firefox, Chrome, Safari, or Opera. PowerLine presentations can be viewed directly in the browser, without any additional installed programs. A PowerLine presentation can either be viewed online over the Internet, or copied onto a computer and viewed off-line, without Internet connection.
An SVG slide presentation is a set of SVG files, where each file is one slide. SVG (Scalable Vector Graphics) is the W3C standard for vector graphics. It can be displayed in any major modern browser.
PowerLine is programmed in Java, so that it runs on Mac as well as on Windows PC computers.
PowerLine can export TIKZ files. This means that you can draw your figures in PowerLine and then save them in TIKZ. TIKZ can be included in Latex documents. This way, PowerLine doubles as a what-you-see-is-what-you-get GUI software for TIKZ, LaTex, and PDF, instead of Beamer. If you have LaTex installed, you can compile your PowerLine presentation to PDF right away. The LaTex features have been tested only for drawings made in PowerLine. Other, external SVG files might not work as expected.
As an experimental feature, PowerLine can export the drawings to SVG fonts. For this purpose, every slide has to contain one character drawing. Thus, PowerLine can be used to design SVG fonts. To convert these fonts to truetype, use the SVG to TTF font converter.
PowerLine comes with its own font, Fabiana. You can use it in your slides, but you are not obliged to. If you create a slideshow in PowerLine, the Fabiana Font is included as a WOFF file in the folder of the presentation, and referenced as a font-face from each SVG file. If you create a single image in PowerLine, the Fabiana Font is embedded as path elements into the SVG file. In that case, no external font file or dependency is required.
