Slidie is a slide preparation system which makes illustrations easy and bullet points hard.
Slidie is a light-touch tool for converting a directory full of Inkscape SVGs into a slide show to accompany a presentation.
Noteworthy features include:
- Slides are just ordinary (numbered) Inkscape SVG files
- No Inkscape plugins etc. are required
- Reveal complex diagrams step-by-step by adding Beamer-like annotations to Inkscape layer names.
- Export to multiple output formats (PDF, single-file browser-based viewer and PNG files)
- Hyperlinking between slides
- Speaker notes
- Presenter view
- Embedded videos and iframes
- Embedded fonts
Most of my slides are diagrams and drawings and yet every presentation tool I've used has very limited (and often buggy) drawing facilities. As a result, for years now I've been creating slides entirely in Inkscape: a tool which excels at drawing and diagramming. Unfortunately, combining these into format suitable for presenting (e.g. a PDF) is fairly tedious.
In the past I've used flaky GNU parallel one-liners to convert many SVGs into a single PDF for presenting but this approach leaves much to be desired. In particular, step-by-step builds often require duplicated SVG files with different layers turned on and off but you don't need me to elaborate on the many problems this leads to.
Slidie's raison d'etre is to provide a robust mechanism for combing slides and handling builds involving showing/hiding combinations of layers. Using Beamer-inspired annotations in Inkscape layer names, Slidie makes it possible to have a complex diagram build-up step-by-step from a single Inkscape SVG file.
Everything else is just gravy.
It's slow, it's buggy, it's drawing tools are awkward and limited, it comes in three not-quite-compatible implementations (Windows, Mac and Web) and it costs a lot of money.
Many of the same criticisms as PowerPoint apply, although it is fractionally less buggy and costs a lot less money.
I'm not a fan of MacOS and don't have a Mac so this isn't a practical option.
JessyInk is certainly a spiritual ancestor of Slidie and probably what originally gave me the idea of using Inkscape to create whole slides (not just the diagrams) in the first place.
Unfortunately JessyInk is very constrained. Your slides must live in a single file and layers are repurposed only for slide boundaries. There's also no way to export to static formats like PDF. Further, bare SVG are not a good distribution format since they do not natively support embedding of fonts.
Despite having pulled a few stunts with Beamer and TikZ in the past, I've reluctantly concluded it usually just too slow to author for slides in most situations.
They're cool too, but I just don't support them (yet). You can still use these to create slides, but Slidie's step-by-step build-up system currently depends on Inkscape's layers mechanism and so this feature will not be usable.
