This is a rough plan for the future of the tikzDevice up to version 1.0
See milestone v0.6 for development status.
Support for new graphics primitives that were added after R 2.10.x
- Raster images (Issue 8)
- Polypaths (polygons w/ holes)
Initial UTF8 Support
- Get UTF8 working in some preliminary way
- Sort out all the hairy details associated with accepting this kind of input (metrics in particular)
Refactor package support systems
See milestone v0.7 for development status.
Support for all LaTeX engines
xelatex(native UTF8 support)
lualatex(native UTF8 support) See issue #28.
Investigate ways to speed up metrics calculations
As much ~50% of the time involved in producing a figure using
tikz can be spent inside the metrics calculation routines. Some ideas for speeding this up:
.fmtfile (a.k.a. precompiled preamble) for each graphics device. This may drop the amount of time it takes a TeX engine to start up.
Instead of making a system call to TeX each time a calculation needs to be done, start one instance of the TeX engine per graphics device and use interprocess communication to extract metrics from it.
This probably won't work. The problem is that in order to get real call and response communication with a subprogram, the caller has to communicate with it via a pseudo-terminal or some sort of console device on Windows. The logistics of doing this reliably in a cross-platform manner are mind-bogglingly difficult. As far as I know, noone has even made a cross platform library that solves this problem.
Some detailed profiling is needed to determine the best course of action.
Support for TikZ annotations in Grid Graphics
Two step process for adding support for
tikzCoord in Grid-based graphics:
Add functionality for converting Grid coordinates to device coordinates and for representing TikZ annotations as Grid
grobobjects. Work progressing in issue #37.
Add functionality for adding annotations to GGplot graphics. This is difficult as GGplot2 has an additional level of coordinate system manipulation that exists above the Grid coordinate system.
See milestone v0.8 for development status.
Support for all TeX dialects
In addition to LaTeX, add support for:
- More R functions for outputting custom TikZ code?
- Raster "screen shots" (Issue 9)?
- Incorporate alien technology?
Convince Kanye West to do a rap about us.
- Remove beta flag.
- Clothing line.
- tikzDevice fruit snacks.
- Prepare for the development of tikzDevice v. 2.0: Electric Boogaloo, which will support breakdancing as a viable means of entering UTF-8 encoded information.
Ideas that don't have a home yet.
Support Moar Graphics Packages
Asymptote: Would be fun because it can embed 3D imagry into TeX documents.
PSTricks: Possibly. But I'm not getting a warm fuzzy feeling about this one at the moment.
Spot Color Support
Would be great for authors who want to take advantage of two-color printing. Experimental implementation in the METAPOST branch. Difficult because it requires dodging around the R color handling system.
