I centos 5 I can run this command: su myuser -c "/usr/bin/gconftool-2 -t string --set /desktop/gnome/background/picture_filename /usr/share/backgrounds/images/mypic.png" and this works fine. under centos 6 it does not appear to be working... I can run the similiar --get command and it tells me its set to what I asked for. However the screen is not showing mypic.png I can use gconf-editor to set it manually and it works. I looked to see if gconfd-2 is r...

...ssible, due to the huge size of the pdf pictures produced. The first solution I found was to save pictures in png, when too heavy in pdf. Here is an example: ### in a .rnw document ### % here is an invisible chunck to create a picture <<fig =FALSE,echo=FALSE>>= png(filename='figs/myPic.png') @ % next, R code to generate picture <<fig=FALSE,echo=TRUE>>= ...[code to produce the figure] @ % then, close the device. Hidden, again <<fig =FALSE,echo=FALSE>>= dev.off() @ % and then, include it as a picture \includegraphics{figs/myPic.png} ### end of the ex...

Hi, I''m trying to figure out the best way to protect images uploaded by users who may wish to keep them private. For example, if they are uploaded in the default file_column location (/public/blah/blah/1/) then someone can simply type the URL http://www.blah.com/blah/blah/1 and get the image. I can store the images in a non-public directory in the rails app (ie: /railsapp/images/X/)

Hi there, I am working in a RoR application which allows certain users to upload files. Currently I store these files in a directory called "files". This directory is located in the RoR application directory: rails/rails_application/files So users don''t have access to them. Now I want users to be able to download some of these files (they will search based on some

Dear All, I have some code that works in S-Plus for writing saving a graphics file to disk :- graphsheet(type = "auto", format = "WMF", file = "G:\\north0l.wmf", pages = "auto", print.background = F, orientation="landscape", color.style="color") plot(x,y) dev.off() This works fine in S-Plus. I have tried playing

...simplest "dirty" way to get the problem solved. But I ran into yet another interesting but quite round-about way to solve the problem (partially). Through tcltk package, one can read in the gif image with > x <- tkcmd("image", "create", "photo", file=mypic.gif) > x.data <- tkcmd(x, "data") gives you the data for the image, but is in a format internal to tcltk. But then it turns out that the format is very straightforward to understand: the enclosed simple function decodes the format and returns a matrix for the data, > x.data.ascii...
