Hi This appears to be happening (at least) because cairo_pdf() delays initialising a Cairo surface until BM_NewPage(), rather than initiliasing a Cairo surface in BM_Open(), and replayPlot() triggers some activity (set clip region) on the device BEFORE a new page is started (so the pointer to the Cairo surface is null, so BOOM). Not sure yet whether to...

...an annotated map of China with R and some public GIS data: http://sourceforge.net/projects/outmodedbonsai/files/snpMatrix%20next/1.17.7.11/China_Choropleth_Maps.pdf/download It is done, and rather nice... there are a few issues: - the default pdf() device cannot do CJK with embedded fonts - and cairo_pdf() is not hooked up to Sweave yet. I have had a quick look, and it does not look too complicated, other than the fact that cairo_pdf() is mutually exclusive with pdf(); and the jpeg/png are new to 2.13 so it is probably just nobody has gotten round to it. (and cairo_pdf() also behaves differently wi...

Hi I decided to blame cairo_pdf(). There is a fix in r-devel (r72242) that works for the reported case, plus some basic sanity checks. I could not complete 'make check-devel' because it was failing on reg-tests-1d.R ... > stopifnot(length(fd) == 10, identical(fd, format(dct <- as.POSIXct(dlt)))) Error: identi...

Hello all, When producing a plot in R using the cairo_pdf device, the resultant plot does not respect the plotting boundaries. Lines and shaded regions will spill over the lower x-axis and the right-side y-axis (sides 1 and 4). I would like to know if it is possible to fix this behaviour when using 'cairo_pdf' in R? As an example, see the image a...

...graphics.org/manual/cairo-cairo-surface-t.html for the call you would need to add. However, I would suggest that you generate a bitmap directly and use that, as PostScript does not support semi-transparency.

X11() *is* by default the "X11cairo" device and that works, the same as the "Cairo PDF" device that Jeff mentioned above. Indeed, cairo_pdf("utf8-ex.pdf") # works nicely whereas pdf("utf8-ex.pdf") does not {for me, with default font families etc}, but rather shows the "..." instead. *and* gives warnings during the plot conversion failure on 'EVENT ? 30 sec' in 'mbcsToSbcs': dot substi...

Hi, Am using R 2.13.1 on Linux (Fedora). Is anybody else having problems with dev.copy2pdf xyplot output with the pch=1 (open circle) symbol? The symbols come out as "q" in the PDF. dev.copy2eps produces the correct results as does cairo_pdf. Other symbols produced with dev.copy2pdf seem ok. Thanks, Selwyn

Hi all, I have the following problem: Since R 3.4.0, italic fonts rendered on Cairo devices appear pixelated. Here's a minimal example: cairo_pdf('test.pdf') plot(1:10, ylab=expression(italic(test))) dev.off() The same problem occurs with bolditalic, but not bold. I am using Debian Stretch. Several friends tried the same on their machines, another Debian machine has the same problem. On MacOSX the output was not pixelated, but it...
