I was wondering if someone could help with the antialias option in tiff(). I'm running R 2.9.2 on a Linux machine. I'm working on creating a tiff file and have tried different antialias parameters, e.g. default, none, gray, and subpixel, but don't seem to be seeing a difference in the output. Or perhaps I'm missing something obvious?...

using X11(antialias="none") plot(1:10) produces an incomplete plot with 2.7.0. under MacOS 10.4.11: both y-axes are missing.the y-ticks (except the tick at `2' wich is missing) including labels are there. this happens with a 1280x854 labtop monitor. is this known behaviour/a cairo bug? joerg

...On my system (Windows 7, running R 3.4.2), this produces a plot that is 755 x 200 pixels, and is vertically very squashed. Looking at grDevices::jpeg, it looks like the culprit is these lines: g <- .geometry(width, height, units, res) if (match.arg(type) == "cairo") { antialias <- match(match.arg(antialias), aa.cairo) invisible(.External(C_devCairo, filename, 3L, g$width, height, pointsize, bg, res, antialias, quality, if (nzchar(family)) family else "sans", 300)) } g$width is used, but "height" is used instead o...

I have a question about antialiasing when R generates bitmaps. (This follows a thread on the ggplot2 mailing list.) I mostly use R on Linux, although I sometimes use it in Mac and Windows as well. On Linux, I've found that plotting shapes 15-18 via cairo results in bad-looking output. The points are not antialiased, and they a...

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

I have gs 6.51 installed & R_GSCMD=/usr/bin/gs set. generating Rplot.ps; pstoimg -antialias (or pstopnm) would also be an acceptable solution if I knew how to control the size of the generated image, or if the ps generated by R was consistently compatible with pstopnm.

Hello, Wine Users! I'm on Debian Sid (x86_64) using fglrx. Wine version is stable 1.4.0 The driver is working fine and I can play Warcraft 3 with 1920x1080 resolution with highest settings, getting about 100 FPS. Now, that's the fine part. Now the problem: I can't get anti-aliasing to work. It doesn't matter what options I select or deselect in the Catalyst Control Center,

Hi, I need a relatively simple image api for the app I''m writing. I need to copy photos, rename them, and re-size them to put them in a standard format. I tried using RMagick/Imagemagick, but the photos would be corrupted on re-size, so I''m looking for some suggestions. -- Posted via http://www.ruby-forum.com/.

under Ubuntu 9.04 R seems to be very slow at plotting. the example below illustrates with a plot of error bars of sample means where i watch as each error bar is plotted one at a time. very annoying and pain in the neck when running Sweave repeatedly. running R 2.9.1 under Windoze on the same machine the error bars plotted in the code below appear instantaneously. has anyone else noticed this
