Re: [R] png scaling problem
Knut, Gabor has provided a possible approach here. Your comments on using postscript make me wonder how your code looked. The following, for example, will create a 4 inch by 4 inch square plot to an encapsulated postscript file (EPS). It will also specify/include required resources for the Helvetica font, which is one of the requirements on the page you reference. Since Helvetica is one of the standard Adobe PS fonts, I don't believe that it is necessary to actually embed the font here, which would be the case if you used a non-standard font. If you open the EPS file in a text editor, you will see many lines referring to 'Resources' and fonts. postscript(RPlot.eps, onefile = FALSE, horizontal = FALSE, paper = special, height = 4, width = 4, family = Helvetica, font = Helvetica) barplot(1:10) dev.off() They keys above are the 'onefile', 'horizontal' and 'paper' arguments, which must be set as above to generate an EPS file with the specified size and bounding box. The page referenced mentions creating the image as close as possible to the actual size required, so be sure to set the 'height' and 'width' arguments per that specification. Using postscript here will also better enable the 50% reduction that is mentioned, given the vector based format here. The key here also is to be sure that the plot looks good in the target format, not on the screen, which includes text size, readability and positioning, etc. HTH, Marc Schwartz On Fri, 2005-09-02 at 02:03 -0400, Gabor Grothendieck wrote: If you have not already tried it try creating a fig file: xfig(myfile.fig) plot(1:10) dev.off() and then using the fig2dev utility (find it via google) to convert it to a tiff: fig2dev -L tiff myfile.fig myfile.tiff On 9/2/05, Knut Krueger [EMAIL PROTECTED] wrote: Probably a better first question is, why are you using a bitmapped graphics format if you need the image to be re-scaled?

Re: [R] png scaling problem
I can't reproduce this problem. It works fine for me. Some possibilities are: 1. check which version of fig2dev you are using. If you are on Windows I am using the fig2dev that comes in winfgi142.zip by Andreas Schmidt found at: http://user.cs.tu-berlin.de/~huluvu/WinFIG.htm Here is the version info I get: C:\binfig2dev -h | findstr Windows Windows version 2 (02/08/2004) by Andreas Schmidt 2. Also, it seems from your output that fig2dev uses ghostscript. I am using ghostscript 8.13. Check what version you are using.

However, the PNG files, as a result of your attempt to scale the plot, do not have enough margin space for side = 2 (left). You would need to adjust the settings for par(mar) and perhaps adjust the overall plot size in the png() call. This is one of the reasons why trying to scale a bitmapped image is problematic. If you want to have finer control over the text annotation, use something like the following: # Create just the 'bare' barplot and save the bar # midpoints in 'mp' mp - barplot(1:10, xaxt = n, yaxt = n, ann = FALSE) # Now create the x axis labels, using 'mp' for placement # 'cex' controls text size. # See ?axis for more details axis(1, at = mp, labels = LETTERS[1:10], cex = 1.25) # Do the same for the y axis axis(2, at = seq(0, 10, 2), cex = 1) # Do the x axis label, using mtext() # See ?mtext mtext(1, line = 3, text = X Axis Label, cex = 1.5) # Same for y axis mtext(2, line = 2.5, text = y Axis Label, cex = 1.5) # Now the title mtext(3, line = 2, text = Main Barplot Title, cex = 4) Again, with the above, be sure to check the output in the target format, not on the screen. They will not always be the same.

Re: [R] png scaling problem - solved :-)
Yet another Windows solution without winfig: 1. Create a postscript image in R 2. Open this image in Ghostscript 3. Select a reasonable resolution using Display Settings in ghostscript 4. Copy the image via clipboard into your favorite image viewer (e.g. IrfanView) 5. Save the image in the required format. Thomas P.

If you are going to print the graphic directly or include it in a document for printing (as opposed to just viewing it), then use PDF or Postscript. The latter in EPS format, can be imported into many Windows applications like Word, including the generation of a preview image. However, they don't look good for direct use in presentations (unless you print to a PS file and then convert to PDF for viewing). See ?Devices for more information. With a better idea of how you plan to use the graphic(s), we can offer more specific recommendations on how to proceed.
