Re: [R] transparent background for PDF
As far as I know, PowerPoint does not import pdfs. Without telling you it transforms it in a png. And it is not very smart about making a high res png at that. Maybe it is also not very clever about taking the transparent background into account? When I must use PowerPoint, I either transform the pdf in png myself, or prepare the presentation in Keynote and export to PowerPoint format. This also translates the pdf figures into png figures, but at much better resolution than what PowerPoint does. I tried making both pdf and png from my R program. I had hoped I would use the same settings for both devices (just copy and paste the plot instructions into a call for each device), unfortunately it did not work because to do better than PowerPoint's translation, I had to save the png version of my plots at high resolution, and that meant that all of the plot adjustments I made so that the pdf version looked nice (position of text, size of margins, etc) had to be fine- tuned differently for the png version, which was too time consuming...

Re: [R] transparent background for PDF
Hi Dennis Out of curiosity, how did you import the pdf to Power Point? I am running windows so it may be different (and completelly irrelevant to you!) but when I want to place a pdf image in a PPT slide I copy the file to the clipboard and then paste it in Power Point. Then in Power Point you can right click on the image- show picture toolbar and then use the tool Set Transparent Color. That will give you a transparent background but you may not get be the best quality, so in general I prefer to save the image as a bmp or some other format and then insert that into Power Point directly using the Insert menu in PPT. I hope this helps Francisco From: Jari Oksanen [EMAIL PROTECTED] To: Dennis Fisher [EMAIL PROTECTED] CC: r-help@stat.math.ethz.ch Subject: Re: [R] transparent background for PDF Date: Fri, 24 Mar 2006 21:11:52 +0200 On 24 Mar 2006, at 20:30, Dennis Fisher wrote: Colleagues Running R2.2.1 on either a Linux (RedHat 9) or Mac (10.4) platform.
