Hi all,
I believe I've run into this before, but I seem to have totally
forgotten. No headway in the last couple of hours either. How do I
make sure that points and margins remain the same absolute size as I
change
the resolution of a device?
(I'm running 2.9.1 patched, on a Win XP-machine)
Many thanks in advance,
Gustaf
Ps: As an afterthought, might it be that this behaviour is related to
the receng grid-bug for text size in lattice when changing resolution?

Example:
.....
###This give a totally squished graph, where the actual plotting area is minimal
CairoPNG("example.png",width = 480, height = 480,
dpi=600,
pointsize = 12, bg = "white")
bwplot(decrease ~ treatment, OrchardSprays, groups = rowpos,
panel = "panel.superpose",
panel.groups = "panel.linejoin",
xlab = "treatment",
key = list(lines = Rows(trellis.par.get("superpose.line"),
c(1:7, 1)),
text = list(lab = as.character(unique(OrchardSprays$rowpos))),
columns = 4, title = "Row position"))
dev.off()
### This gives a more norma looking graph
CairoPNG("example2.png",width = 480, height = 480,
dpi=20,
pointsize = 12, bg = "white")
bwplot(decrease ~ treatment, OrchardSprays, groups = rowpos,
panel = "panel.superpose",
panel.groups = "panel.linejoin",
xlab = "treatment",
key = list(lines = Rows(trellis.par.get("superpose.line"),
c(1:7, 1)),
text = list(lab = as.character(unique(OrchardSprays$rowpos))),
columns = 4, title = "Row position"))
dev.off()
