similar to: Antialiasing plots and text on different devices

Hi, It seems that anti-aliasing in png(type = 'cairo') is not well supported for the point symbols without boarders, e.g. pch = 16. The Cairo package works well, though. You can compare png() with CairoPNG(): png(): http://i.imgur.com/8niB3jX.png CairoPNG(): http://i.imgur.com/FZBJOxm.png f = function(dev, ..., main = '') { dev(...) plot(c(1, 2, 1, 2), c(1, 1, 2, 2),

Dear all, I am trying to use the Cairo package to avoid some X11 issues and it works very well. However, when I want to add a legend to my plots, I receive an error message from Cairo: > library(Cairo) > CairoPNG(file="test.png") > plot(1:100) > dev.off() null device 1 This works fine. But: > CairoPNG(file="test.png") > plot(1:100) >

Does wxRuby support font antialiasing on Linux or does it depend on the underlying toolkit? If not, are there plans to include it? If I use wxGTK, is antialiasing automatically enabled? Do I have to do something to make my fonts antialiased? Bill

I have been plotting the same charts using png on a Windows machine and on a Mac OSX and the quality of the resulting images, particularly in relation to the fonts, look far superior in the plots produced on the Mac. Is there any way I can enhance the quality of the plots produced on the Windows machine? I have also tried using win.metafile on the Windows machine and the quality looks the same as

Hi, could it be that the text() fuction gives different output for normal png() and CarioPNG()? See the following example and the attached images: the font=2 and font=3 seem to be exchanged! Thanks for help, Thomas CairoPNG("Test-cairo.png",width=750,height=690) #png("Test-normal.png",width=750,height=690) plot(1,1,type="n",main="normal")

Hi All, I have been experiencing a strange issue ever since I upgraded my R and the packages. I cannot plot anything to the CairoPNG device.For an example:> Cairo(600, 600, file="plot.png", type="png", bg="white")> plot(1:10)> dev.off()will create an empty plot.png file. I am running R 2.12.1 (32bit) on Windows 7 (64bit). ----------------------------->

Hello, I am generating .png images using the Cairo package in a for loop (looping on the number of zones, number of zones equals the number of plots to create based on different zone data). When I run the R script the .png files are created but they are all black? If I comment out the for loop and force my zones to equal one the png file is created correctly? Is there an issue with

Hello, I am creating plots of hourly precipitation and accumulated precipitation (on different axis, see attached image). I was wondering how can I have the plot frame (black border) start at zero, it looks like it is plotted less than zero? The code I use to create the png files is below: CairoPNG(PNG_file,width=1000, height=600, pointsize=14, bg="white") opar <-

Hi All, I just installed Cairo on R 2.5.1 on windows XP. My hope was to get to see the transparency output e.g. http://had.co.nz/ggplot2/stat_smooth.html ggplot2 - stat_smooth , which I finally managed to do. However, I find the Cairo device, which I access either through CairoWin() or Cairo(type="win"), is pretty shaky in a number of respects : - whatever portion of the Cairo

I've been a R-user for quite some time. The graphic on the home page looks a bit in need of polish so I applied some antialiased transformations that Peter Dalgaard has previously posted to R-help for improving graphic quality. I had to change the margins a bit, but here is what it looks like: http://www.broad.mit.edu/~finnyk/Rhome.jpg Personally, I think it looks much better. Because

One new thing I have found with Wine 0.9.17 is the inclusion of anitaliased text. Winecfg et. al. now have their text antialiased. I don't know if this is a new feature (i'll go dig in the ChangeLogs), but it is a significant improvement in the user experience. -- The real problem with C++ for kernel modules is: the language just sucks. -- Linus Torvalds

Is there a way to get Wine to use Render extension in XFree86 4.0.3 to allow it to have antialiased fonts? David

I've got R running on a gentoo server that doesn't have X11 installed. Its a custom build to keep those dependencies at bay! However, some of my scripts use the base png() function and ggplot2. But, png uses X11. A google search suggests using the Cairo package, which works... but changes the fonts (specifically the size of the font). Adjusting the pointsize doesn't seem to have

Hi all, I believe I've run into this before, but I seem to have totally forgotten. No headway in the last couple of hours either. How do I make sure that points and margins remain the same absolute size as I change the resolution of a device? (I'm running 2.9.1 patched, on a Win XP-machine) Many thanks in advance, Gustaf Ps: As an afterthought, might it be that this behaviour is

I''m doing a graphics application and need onscreen anti-aliasing for both lines and text. Seems like wxGraphicsContext would do that, is that planned to be ported to wxRuby? Best regards, Jari Williamsson

Hi, I've noticed that font antialiasing is enabled in the console window, but not in the editor windows. I'm using R version 2.12.1. JGR 1.7.4 and the jdk from Ubuntu 10.04, which claims to be: OpenJDK Runtime Environment (IcedTea6 1.9.5) (6b20-1.9.5-0ubuntu1~10.04.1). Is that a problem with my installation? Has someone else noticed that issue? Regards, Matthias

Finally, the RPMs for 2.7.0 arrived, but it looks like they were not built against the Cairo libs, at least not on F8 (based on the reports, I should probably wait a couple of weeks before upgrading to F9). > capabilities() jpeg png tcltk X11 aqua http/ftp sockets libxml TRUE TRUE TRUE TRUE FALSE TRUE TRUE TRUE fifo cledit

Hello, I'm running Fallout New Vegas in Wine with (a lot of) help from Playonlinux. I have to say it is running very well and I'm have very few critical failures like I was having with the game in Windoze; many quirks, but few critical failures. Which is awesome. I'm wondering though, if anyone else who's got FONV working has found a way to initiate anti-aliasing in the game. For

Hi I was trying to run mu-online, I'm using wine 1.3.10 under kubuntu 10.04 The game installs(with vcrun2005,vcrun2008 and mcf42 from winetricks) But I can't see the fonts. To see the fonts I read I have to disable anti-aliasing, this was possible in older versions of wine, but for some reasons it was disabled, or moved, any idea on how I can disable anti-aliasing? It's not a

I've narrowed the my Cups printing problem down to Wine not loading my Type 1 fonts. I have several Type 1 fonts installed in 3 places, all of which are in my fontpath ("xset q" lists them). I can use the Type 1 fonts in X and with KDE-2.2.1 even as AntiAliased, however, when I try to print from an app under wine I get a memory error and a message at the command line stating
