minipdf 0.2.5 (The Updatening)

  • Update roxygen to latest
  • Use roxygen for R6 documentation
  • Remove dependency on ‘glue’
  • Remove Travis CI and replace with Github Actions

minipdf 0.2.4

  • Add a $show() method to PDFDocument. In Rstudio, this will launch a PDF app to view the current document.

minipdf 0.2.3

  • Curtailed the accessability to global clipping path as it is cumulative and not resettable within a document making it a bit of a sledghammer.
  • Instead use clip_path() or clip_rect() on specific objects
  • Renamed the stream helper to ptag to be more reminiscent of the tag helper from shiny

minipdf 0.2.2

  • draw state parameters are now set via their own methods e.g. obj$fill('black'), however using update() still works e.g. obj$update(fill = 'black')
  • refactored internal attrib handling.

minipdf 0.2.1

  • transformations are now methods directly on the PDFStream object rather than attributes
    • e.g. obj <- PDFRect$new(x=0, y=0, width=100, height=100)$translate(0, 100)
  • renaming of some methods in PDFDocument
    • e.g. add_rect() has become just rect
    • add() is now append()

minipdf 0.2.0

  • Building a document is now much more structured - the main objects within a PDF now classifed as either Dictionary or Stream objects (with R6 objects to represent both).
  • Since R6 objects are used throughout to represent PDF stream/dict objects, we can make use of R6’s reference semantics to update individual nodes within a document in-situ i.e. without having to recreate the document from scratch.
  • The ptag data structure can be used to build R6 PDFStream objects of the required sub-class e.g. ptag() will help create a PDFRect object.
  • The dict function can be used to build R6 PDFDict objects.
  • Alternately, the PDFDocument class includes helper methods (e.g. add_rect()) which will create a stream of dict object of the correct type and add it to the document.
  • Text output is formatted much more nicely with better use of indentation and line breaks.
  • The tidy-friendly helper functions have been removed. This was partly due to the namespace pollution of having all these functions exported from the package, but also due to the finnicky way the R6 methods were exported as package functions.
  • All these changes mean that updating and extending minipdf will be much easier than before.

minipdf 0.1.0

  • Initial release.
