Dear all,
When saving a plot with the dev2bitmap command:
name <- c("test.jpeg")
dev2bitmap(name,type="jpeg",height=8,width=13,res=400)
Everything seems to be ok... After importing this picture in CORELDRAW (for
a poster A0) format the resolution and colors are not optimal.
How can I save pictures (colors/resolution) optimally for import into
CorelDraw for an A0 poster?
Pdf?/tiff?/bmp?/
Thanks,
Jan

What about PostScript? It's perfectly resizable and CorelDraw (at least the outdated version 10) can deal with it. Uwe Ligges
Thanks, Jan

But not PDF? Notice that this is not really bitmapped either, even though handled by dev2bitmap. Upping the res= is another option, but may be memory intensive. Notice that A0 is 4 times as big as A4 (~8x12 inches) so you'd need up to 4 times the resolution - but I guess that your plot is not taking up the whole area...

Thanks for the input! Finally I used: dev2bitmap(name,type="pdfwrite",height=8,width=14,res=1200) ==> resolution and colors were fine on the A0 poster! (and files are really small).

Why not use R's native PDF driver if PDF is acceptable? This is a convoluted way to produce PDF by converting EPS.
