In addition, PowerLine has native support for LaTex, meaning that PowerLine presentations can contain basic Latex formulas — no plug-in and no Latex installation required. PowerLine can also export and convert its SVG files to TIKZ files and to LaTex files.
PowerLine is a tool to create HTML/SVG slide presentations. This means that the native file format of PowerLine is an HTML file with embedded SVG images. PowerLine can also create SVG images or SVG posters. The graphical user interface of PowerLine 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. If you want, you can export individual slides to TEX, TIKZ, or SVG. The presentation is automatically saved when you quit PowerLine.
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.
PowerLine is programmed in Java, so that it runs on Mac as well as on Windows PC computers. For technical reasons, you cannot rename a PowerLine presentation file (if you rename it, the presentation stops working). This is because the hyperreferences from one slide to the other have to contain the filename.
PowerLine can export individual slides to TIKZ files. The TIKZ files can then be included in Latex documents.
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 export a slide presentation as a font, hit the key “[”. To convert the font 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 embedded as a WOFF file in the presentation. 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.
Displaying presentations on the iPad
You can display PowerLine presentations on an iPad. It suffices to open the presentation on the iPad (e.g., in Safari), and to connect the iPad to the projector. The Safari browser always shows a tab header, which can be disturbing. To avoid this, you can use a full-screen browser, e.g., the Blink Browser.
