Colleagues Running R2.2.1 on either a Linux (RedHat 9) or Mac (10.4) platform. I created a PDF document using pdf("FILENAME.pdf", bg="transparent", version="1.4"). I then imported the graphic into PowerPoint - background was set to a non-transparent color. I was hoping that the inserted graphic would be transparent - instead, it had a white background. The help pages indicate: The 'version' argument m...

Dear R users, since R-2.4.0 I am not able any more to draw figures without transparency after drawing one figure with alphachannel set lower than 100%. For better unterstanding here a small example of my problem: ----------------------------------------------- pdf(paste("test_alpha_rgb.pdf",sep=""), version="1.4") plot(1:8, 1:8, type="n",

...e that could (1) create 3D surface plots, (2) handle transparency/alpha blending, (3) generate output in some vector graphics format that preserved the transparency. I could also live with a combination of two programs, one to generate the basic figure and another to modify the output surface to a transparent color (but preserving vector-ness). I've been working with the rgl package, but can't get the transparency to work for vector output (rgl.postscript). The rgl package uses the gl2ps library -- by default transparency is disabled in the output (GL2PS_NO_BLENDING is set), giving reasonabl...

...t for real transparency to kdesktop. It adds two new composite manager related features. To activate the features kdesktop has to be started with the "--bg-transparency" option. The first one allows you to change the opacity of the background image. This works currently with the beryl transparent cube and will also work with compiz once the transparent cube gets applied. To activate the feature add the following to your kdesktoprc: [Background Common] BackgroundOpacity=90 (0 = fully transparent / 100 = opaque) The second feature allows compiz (and later maybe other composite managers) to...

...er). I think this is unsatisfactory, and inconsistent with the way colour is handled for filled objects (rectangles and circles). Not painting a white background is also undocumented! For 1.3.1 I think we should document this, and alter win.metafile and win.printer to make a white background mean transparent. (I've tested that, and it works.) However, for the future (1.4.x), I think we should handle "white" and "transparent" differently, and have bg default to "transparent" for all devices. A quick look shows that this is would be easy, as only 24 bits of the rcolor...

Hi, I want forward port 21 and 443 to my squid. A simply rule (dnat) didnt help me. My http - port (only 80) will forwarded to my squid. It runs fine. Here I have used the HowTo from Tom and the hints from http://lartc.org/. I want to do the same with port 21 as port 80. My network: Shorewall: eth0 net (192.168.108.1) eth1 dmz (192.168.109.1) eth2 loc (192.168.110.1) eth3 loc1

Dear R-users, I am trying to produce trellis (png, or jpeg) graphs with transparent background, but I cannot manage to make that happen. I tried to play around with themes but to no avail. Any advise on the following example will be greatly appreciated: Thank you Sebastien #### library(lattice) df <- data.frame(a=rep(1:4,4), b=rep(1:4,4), c=rep(1:4,each=4)) settings <-...

I couldn't find this is in the FAQs or in the R archives and I've poked around the lattice package manual, but... I've been trying to figure out how to generate graphics files with a transparent background with the lattice package. The code to generate the levelplot is fine and I can produce a simple png file with a transparent background just fine, but I'm not sure how to generate a png of a lattice plot with a transparent backgound. png( "../images/opt_harvest_pattern_pred.p...

Hello, I can't seem to add transparency to any color ramp I create using colorRampPalette(). Can someone tell me if it is possible to create transparent colour ramps? I am attempting to map shaded relief under elevation data. I know I can use the terrain.colors() with the alpha option, but I would prefer to create my own colour ramp using more vibrant colours. My most recent attempt at doing this involved generating multiple rgb colours with t...

Hi, Recently i have worked on re-writing beryl's transparent cube, and ported 3d plugin to compiz. I'm attaching a patchset here that includes the transparent cube patches (i'll post the 3d plugin when i fix some problems that didn't happen in beryl). Patching order: btf-ftb.patch, clip-planes.patch, plugin-events.patch, cube-paint-order.patch, t...

Hi all, We're running gpfs 3.5.0.12 (5 total nsds & quorum servers, 2 nsds running samba), sernet-samba 4.1.4-7, and ctdb 1.0.114.7-1 and trying to get transparent failover to work from a windows 8 client. We have ctdb failover working, i.e. if I run mmshutdown on one of the nodes the IPs failover in a few seconds after the GPFS mount is unmounted. For our transparent failover test, I open up firefox and start downloading a large file, e.g. a centos 6.5 iso i...

hi all, i have a simple scatter plot, and i'd like to make it so the scatter plot colors are slightly transparent. i see in a previous post that someone mentioned the "alpha" parameter, but i am not sure how it can be used with the 'plot' function [*]. for example, suppose i have: plot(mydata$column1, mydata$column2, col="red", cex=1) i now want to make it so the color of these p...

Hi all, I'm putting a few plots together and wondering what format would be best to export a few scatter plots to Illustrator to make a figure. I'm thinking about overlaying some plot in Illustrator, so the export file type has to be transparent for Illustrator (version 10). I tried PNG and TIFF, but it does not seems to have transparency that is recognized by Illustrator (or Photoshop for that matter). EMF (meta data file) on the other hand is very good. The only problem is that every dot on the plot becomes a vector, which slows the pro...

...ed in latex, where all my figures are .eps graphics (so pdflatex is not an option) and I want to achieve something like the following: three concentric filled circles varying in lightness or saturation. It is easiest to do this using transparency, but in my test using the postscript driver, the transparent color fills do not appear. Is it correct that postscript() does not support transparency? circle <-function (radius = 1, segments=61) { angles <- (0:segments)*2*pi/segments radius * cbind( cos(angles), sin(angles)) } plot(1:5, 1:5, type='n', xlim=c(-1,5), ylim=c(-...

The result I'm aiming to achieve is a bitmap that can be imported into a PowerPoint file that shows what's behind the lines of the plot. There's a way in PowerPoint that almost works. By choosing a colour to set as transparent, what is behind the graphic is indeed visible, but it's at the expense of losing line and text definition. I notice there have been discussions about transparent backgrounds mostly with lattice plots. The problem most people seem to have was getting a blue background when they wanted a white...

Hello, I'm having trouble with using the alpha channel for transparency with lines with lattice levelplots. If I use transparency via the alpha argument to rgb to overplot lines on levelplot the transparent colour affects all of the region colours in the plot. Can anyone explain why the difference in region colours? #### Warning: this code attempts to create PDF files in working directory - they may be downloaded, see below library(lattice) ## prepare data data(volcano) xy <- expand.grid(x = 1...
