search for: 72dpi

The 'at a minimum' information requested by the posting guide is missing. According to their documentation the cairo default fallback resolution is now 300dpi, and when I run your example on Fedora 21 that is what the emitted postscript says it is. You can easily alter the R code to set it to something different: see http://cairographics.org/manual/cairo-cairo-surface-t.html for the

...ve a run of 5 graphs that I want to place them under the same page. Everything works fine to place them in a pdf file , or eps file, but when it comes to have a high quality of 300 dpi these graphs are not good. For example I open the eps file with Adobe Illustrator (AI) and it shows that it is a 72dpi graph. If I start with a 72dpi graph AI cannot improve this to 300 dpi. Q: HOW CAN A GRAPH IN R DIRECTLY SAVED AS 300dpi? What options do I need to add to the postscript function to have a 1 page graph that has these 5 plots and is a 300 dpi graph? Thank you in advance, Aldi Here is what I am...

Dear all, In grDevices R functions cairo_pdf and cairo_ps it is mentioned that when transparency (alpha channels) are used in vector output, it will rasterize the PDF or postscript exported graph at a resolution of 72 dpi : https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/cairo.html You can see the problem if you try library(ggplot2) cairo_ps(file = "test.eps",onefile =

...but the results seem not to be very good. I have submitted the generated figures twice using the above-mentioned method, but the Editor think the resolution is still very low. Finally, i used the Photoshop to check the figure. It seems that its resolution for JPEG (100% printed quality) is about 72dpi. *Does anybody know a better method to save a figure with user-defined resolution in R software, especially high resolution? Could u please show me an example if possible?* I hope to save the figures as TIFF/JPEG format at 1000 dpi. Thanks a lot. -- With Kind Regards, oooO::::::::: (..)::::...

Most importantly it needs to work with 96dpi fonts (rather than Windows' default of 72dpi). The TFTs they have are 1280x1024 and operators prefer the larger font size. Many of the softphones I've tried end up with data elements appearing in weird places (or not visibile at all) with the larger font size. Any thoughts / suggestions / pointers? Thanks in advance.

Hi Has anyone had success with setting image resolution with Rmagick. I am resizing an uploaded image with Rmagick, problem is it keeps the original images resolution and I want to change it to 72dpi. <<<<<< code example >>>>>>>>>> # these are the various techniques I have tried when and after reading the file, trying any or all of them does not work. image_render = Magick::Image.read(temp_path){self.density=72}[0] image_render....

Hi, I want to save a plot in the windows device as png and the default resolution is 72dpi. Is it possible to increase the default resolution to for example 300 dpi? I have thought of using function png(..., res=300), but the problem is that the figure produced this way looks different than the one shown in the windows device. One notable difference is the missing of some ticks i...

..., etc.). The graphs are a bit complex, have many variables, parts and bits, legends, etc. so it would be important to save as it is observed in the current windows device... So, I have two questions: 1. Is there any way to save the graph done in the open x11 device with greater resolution than 72dpi? 2. Is there any way to change this default under windows, so that from now on every time I do a figure, it will be with greater resolution (I image it should be possible through windows.options... but no ideia how)? Any help, will be greatly appreciated, Thanks in advance, Best wishes, Marta

...39;s say scaled to fit the page, then items such as the words "Title Text" would appear the same size. Instead (for the last two) it appears that the same number of pixels are being used, thus the text size appears smaller.

I'm trying to use R in a cgi script to produce graphics files in png format, and I'm having a problem. My shell command line looks like this: R </usr/dfs/auction/eligibility.R --no-save >/tmp/R.out and the line in the R script looks like this: png ("foo.png", pointsize=18) If I run outside the cgi context, it runs great. When run as in a cgi script, I get this error

Hi, I have a question about the graphics changes in 2.7.0. The example is this bit of code: par(mfcol = c(2, 3)) for(i in 1:6) plot(1:10, 1:10, xlab = "xlab", ylab = "ylab", main = "main") In 2.7.0, if I do this interactively (using windows()), I get bold titles. If I do this through a png device, I get regular weight titles. If I do this in 2.6.2, both

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

Hi, I am trying to infer the dimension of an opened bitmap (png, jpeg, bitmap device...) from par() parmeters. From the help on par(), I found that: > dim <- c(400, 200) > png("foo.png", width=dim[1], height=dim[2]) > dim2 <- par("din") * par("cra") / par("cin") > dev.off() > dim2 [1] 399.9999 199.9999 I've tried the above on

I've used to have a script with a barplot command it in, preceded by a png: png(graph.file,height=H,width=W) barplot(t,names.arg=breaks[2:(length(t)+1)],tck=gridlines) -- worked before R 2.6.2. When I tried it in R 2.6.2, which I have for a while but didn't run with that script, it complained, the margins too large, and I've googled the messages from our list where neither

Using R-1.1.1 on RedHatLinux 6.2. I've made some progress, succeeded in outputting bitmap, jpeg, and png files. Yipee. I did them with this command: > dev2bitmap("whatever.bmp",res=300) > dev.print(png, file="myplot.png", width=480, height=480) > dev.print(jpeg, file="myplot.jpg", width=480, height=480) > dev.print(pictex,
