Re: [R] PowerPoint - eps not suitable

Previous posters have argued for EPS files as a desirable transfer format for quality reasons. This is of course true when the output is through a Postscript device.

However, the original poster is making presentations with PowerPoint. Those essentially are projected from the screen -- and screens of Windows PCs are NOT Postscript devices. The version of PowerPoint I have will display a bitmapped, low-resolution preview when EPS is imported, and that is what will be projected. It is passable, but much better can be done!

In this application, I have had best results using cut and paste or the Windows metafile format, both of which (as others have said) give scalable vector graphics. When quirks of Windows metafile arise (as they can do, especially when fonts differ between PCs), I have had good results with PNG for line art and JPG for other art.
