Hi, I see different results in png() and pdf() for polypath() on Windows when using the "winding" rule
## overlapping, both clock-wise x <- cbind(c(.1, .1, .6, .6, NA, .4, .4, .9, .9), c(.1, .6, .6, .1, NA, .4, .9, .9, .4)) pfun <- function() { plot(x) polypath(x * 0.8 + 0.2, rule = "winding", col = "#BEBEBE80") polypath(x, rule = "winding", col = "#BEBEBE80") } ## output "windows.png/pdf" or "unix.png/pdf" label <- .Platform$OS.type png(sprintf("%s.png", label)) pfun() dev.off() pdf(sprintf("%s.pdf", label)) pfun() dev.off() Visually, the result in the "windows.png" file is as if the "evenodd" rule was specified. All other examples unix.pdf, unix.png, windows.pdf give me the expected result - which is "all bounded regions shaded grey, with two tones for the different regions of overlap". The unexpected result is the completely transparent region. Is this a known/expected difference on Windows? I see the unexpected result in 3.3.1 and in R version 3.3.1 Patched (2016-07-27 r70991) on Windows.
