PowerLine is a tool to create SVG slide presentations. You can also create SVG images or SVG posters. The graphical user interface of PowerrLine looks similar to Microsoft Powerpoint. You just drag-and-drop text, images, and shapes into the slide. You can also add math formulas in Latex, which are then rendered in the original Latex math font. This requires neither a Latex installation nor a font installation. 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 any particular software. The presentations can be viewed directly in a browser — in Firefox, Chrome, Safari, or Opera. The presentations 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 the drawings to TIKZ files. The TIKZ files can then be included in Latex documents. PowerLine can also export the entire presentation into TEX. If you have LaTex installed, you can compile the TEX to PDF right away.
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. 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. You can also use other fonts, such as Arial, Times New Roman, or the more generic “serif” and “sans-serif”. For compatibility reasons, the latter two are to be preferred.
