Dear all, In grDevices R functions cairo_pdf and cairo_ps it is mentioned that when transparency (alpha channels) are used in vector output, it will rasterize the PDF or postscript exported graph at a resolution of 72 dpi : https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/cairo.html You can see the problem if you try library(ggplot2) cairo_p...

...anual/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.

...eate .wmf files, which might (and I've read conflicting things about this) be importable into PowerPoint as editable graphics. 4) I found an old suggestion in the archives that an EPS could be imported into PowerPoint and made editable. This almost worked for me (using Inkscape to convert a cairo_ps()-generated file to EPS) -- but only using PowerPoint under Windows, and lots of vectors and all text were lost along the way. Am I on the right track? Am I missing any better pathways? I know similar questions have come up before, but the discussions I found in the archives were old, and mayb...

Hi, Except the function postscript ('file_name.eps'), are there functions to generate an image file in eps format? thanks Carol [[alternative HTML version deleted]]

Dear list, I have non-ascii labels that I want to include somethow in a .eps file for inclusion into a LateX document. Is this possible? What I see is that the (attached) png file looks ok but the .eps renders all non-ascii labels at the bottom as [..]. I've searched around enough to learn that including math labels in a .eps is a problem. Hower, is there a solution too somewhere?

...is uncommon. Good question. Currently, for x11() (and png() etc) the default is taken from X11.options(). So it is possible to set this default for a session, or even for an installation via one of the ?Startup mechanisms (e.g., an R_HOME/etc/Rprofile.site file). For svg(), cairo_pdf(), and cairo_ps(), the default is hard-coded in the function arguments, but I *think* they are used less as default graphics devices. Another option would be to try to detect Fedora and set the default X11.options() differently there. Two problems: I am not sure there is a reliable R code chunk for detectin...

Hi, Following Paul's instruction, I have installed the Cairo. I tried to run the program, and there is no error message at all. I did see the Chinese title in the plot if I ask my RStudio to show the plot (if I type "p1"), but the pdf file shows the plots without the Chinese titles. library(ggplot2) library(gridExtra) df1<-data.frame(x=1:2, y=3:4, z=5:6) #p1<-ggplot(df1,

I have had some fun in the last few days trying to put together 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

Hi By the looks of it, you need to install Cairo graphics ... https://www.cairographics.org/download/ Paul On 13/10/17 15:48, John wrote: > Thanks, Paul.

...type = "quartz". The default type is selected by the new option "bitmapType", and is "quartz" or "cairo" where available. Where cairo 1.2 or later is supported, there is a svg() device to write SVG files, and cairo_pdf() and cairo_ps() devices to write (possibly bitmap) PDF and postscript files via cairo. Some features require cairo >= 1.2, and some which are nominally supported under 1.2 seem to need 1.4 to work well. o There are new bmp() and tiff() devices. o New function devSize() t...
