[Tikzdevice-bugs] clash when package transparent

[Matthieu Stigler]

Hi

I am discovering an interesting issue when using tikz for ggplot2, in a
LaTeX document where package transparent is loaded...

Basically, when the user does not specify explicitely which color should
be used in ggplots bars (the color for outer lines of bars, not for
inner fill), ggplot will not put any. tikz seems to be doing the same.
However, things change when the package transparency is loaded: outer
lines are now visible!

Please compare reproducible example below, adding/removing %
\usepackage{transparent}:

library(ggplot2)
library(tikzDevice)

options( tikzLatexPackages = c(
"\\usepackage{tikz}",
"\\usepackage{transparent}",
"\\usepackage[active,tightpage]{preview}",
"\\PreviewEnvironment{pgfpicture}",
"\\setlength\\PreviewBorder{0pt}")
)

tikz(standAlone=TRUE)
diamonds2<-droplevels(subset(diamonds, color%in%c("E","I")))
qplot(carat, data = diamonds2, geom = "bar", fill =
color)#+myScale_fill3()+scale_colour_manual(value =
rep(c(part1_sec1,part1_sec2),3))
dev.off()

Do you confirm outer lines change with/without pkg transparent or is it
specific to my computer? Were you aware of this? How can one solve it?

Thanks!!

Matthieu

Well, tikz uses its own transparency code (see examples in
http://www.texample.net/tikz/examples/feature/transparency/), and it
seems to conflict with the one in transparent package.

The documentation of transparent package says `Because of the poor
interface for page resources, there can be problems with
packages that also use \pdfpageresources.'. Pgf is one of such
packages: systemlayer/pgfsys-pdftex.def says:
\expandafter\global\expandafter\pdfpageresources\expandafter{\temp}

I'd suggest using tikz transparency code for tikz pictures...

You never learn anything by doing it right.

I second that, TikZ has it's own built-in color handling code and trying to
go around it can be very troublesome. After looking over the documentation
of the transparent package, I don't see any functionality that is not
provided by TikZs color system.

Thanks for your answers!

Well the issue is when on e is using a R -> tikz picture in a latex
class that is using transparent by default! The package transparent is
loaded for other purpose than the tikz code, but yet interacts with
it.... I guess there is no way to prevent this other than removing the
transparent package?

Thanks!!
