similar to: Cairo bitmap output should work without X11 dependency (PR#12529)

Full_Name: Craig Ruff Version: 2.7.1 OS: Irix 6.5.30 Submission from: (NULL) (128.117.8.145) Cairo based bitmap graphics output should work if cairo and R have been compiled without xlib support. 2.7.1 gives the "X11 is not available" message in this case when run interactively, and from my reading the png documentation, calling png(filename=..., type="cairo") should work.

Hello, So the Homebrew community dropped support for --with-cairo which is a shame because --without-x --with-cairo is an important combination for any environment that might need to generate graphics without X11 (or related) dependencies (macOS, headless linux servers). This rejected GitHub PR contains more detail: https://github.com/Homebrew/homebrew-core/pull/24094 (See also these comments:

Greetings R community: Since R 2.9.0+ I have noticed that when I use the default cairo x11() device, if I obscure a device window (or switch virtual desktops), the window does not refresh. I need to move it or resize it to make it redraw. This behavior did not happen before 2.9.0. It also does not occur currently when using the Xlib type in x11. Now, I should make clear that I am not

This question was asked previously here, but not resolved: http://tolstoy.newcastle.edu.au/R/e15/devel/11/08/0307.html The upshot is that cairo is not being used as the default when it is available, even though the documentation says: Default "cairo" where available and reliable, otherwise "Xlib". Here is my system information: % uname -a Linux anvil 2.6.18-194.11.4.el5 #1

Dear All, I am running Debian testing on my box and I have R 2.9.0 installed from the standard repositories. I downloaded the package source from http://cran.r-project.org/web/packages/Cairo/index.html but when I try to install it on my system, this is what I get $ sudo R CMD INSTALL Cairo_1.4-4.tar.gz * Installing to library ?/usr/local/lib/R/site-library? * Installing *source* package ?Cairo?

Hello: I'm running R 2.7.1 in Antix (Mepis kernel but heavily debian based). I have installed libcairo2 (1.6.4-6.1). I tried installing the Cairo package since I'm interested in generating some SVG graphs, and I got the following message: Only partial output (lines with no): .... checking if R was compiled with the RConn patch... no checking cairo.h usability... yes checking cairo.h

Dear Daniel Greenidge, To enable getGraphicsEvent on Cairo, you have two patches to choose from: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=14364 https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951 The second one is by me, and the first one is from five years ago by Hugo Mildenberger. Both patches are very simple, they move some lines enabling getGrahpicsEvent outside of a

Hi Paul, Just checking in to see what the status is. >From my perspective it seems logical to split off X11 into a separate package, so development can proceed at a reasonable rate, but I haven't yet tried to see if that's even possible.

Hi Paul, OK I tried not to make the examples too fancy. Please let me know what you think. They should probably be amended to support the Windows platform, but I think that task would be much easier for someone with access to Windows... By the way I'm Cc'ing Mark O'Connell who shared with me some great getGraphicsEvent examples - well, I found them useful, perhaps if these are going

Hi Paul, Thank you, for some reason I didn't seem to get an email notification for your bugzilla comment! I will try to send you something shortly.

Hi Paul, Thanks for your efforts. Do you have an idea when my patch(es) might be committed? Is there anything I can do to help move this along?

G'day all, I am trying to install the cairo package on FreeBSD and receiving an error to do with Makevars - (I'm not very good at this stuff) so here is my various bits of information. I guess this is a problem with a missing library, but I have just been through a lot of grief trying to get png and jpeg to work (they do now work!), so I'm not sure where to go for this. R

Hi Paul, Thanks for keeping me posted and letting me know what I should do. Are there regression tests for other graphics functions in R? To me that sounds a bit unnecessary. I think you get more testing from people who use R; and having a good turnaround for applying patches (some have been waiting 5 years) would invite better participation. Thank you, Frederick On Fri, Dec 09, 2016 at

Hi! On Fedora 18 [1] and Arch Linux [2], using R 2.15.2, X11 plots are not drawn (i.e. the window stays blank) when using X11.options(type="cairo") and X11.options(type="dbcairo"). They are correctly drawn when using X11.options(type="nbcairo") and X11.options(type="xlib"), or after resizing the X11 window. The bug happens with Cairo 1.12.4 and above, but

Hey, I'm running R in ubuntu 10.10 (R-2.15.0) and when saving a plot i get the following error message: > plot(1:10) > savePlot("test.png",type="png") Error in savePlot("test.png", type = "png") : can only copy from 'X11(type="*cairo")' devices > Thanks in advance [[alternative HTML version deleted]]

I am connecting from a PC to a Linux system running CentOS release 5.5 (Final) and it is extremely slow to render plots to the X11 device. This is not R's fault but I wonder if anyone can offer guidance so I can help the system administrators address the problem. I can connect to the Linux server using a NoMachine NX client for Windows or using X-Win32. I also have access to R running

Hi Taking a look at those patches is now on my todo list, so I may be in touch with both of you at some point to request some testing.

Hi all, I'm writing an interactive plotting function for viewing fMRI datasets. Currently, I get keypresses using grDevices::getGraphicsEvent(). Unfortunately getGraphicsEvent() only supports the X11(type="Xlib") graphics device on Unix systems. The Xlib device doesn't support buffering (i.e. dev.hold() and dev.flush()), so redrawing the plots causes lots of flickering. Is
