HexaPDFHexaPDF 0.34.0 - Optional Content aka Layers Published on
The highlight of this release is the support for optional content aka layers.
Optional content allows one to selectively show or hide content. It is most often used to provide something akin to layers, think a building plan with separate layers for the walls, electrical infrastructure, furniture and so on. However, it can also be used for something more mundane, like hiding the answers of a quiz.
Apart from this larger change there is a new style property HexaPDF::Layout::Style#fill_horizontal which allows a text fragment to fill the remaining space of a line. This is very useful when creating table of content entries.
There is new documentation for the optional content feature and the document creation section got a new how-tos section which will be expanded in the future.
As always, have a look at the changelog for an overview of all changes.
