[R-sig-Geo] Increasing font size in a levelplot graphic

[Thiago V. dos Santos]

Oscar and Pascal,

Thank you for the suggestions. Both of them solved my problem.

Best,
Thiago.

Hi,

On the other hand, perhaps your problem arises when you export the
graphic using large values for width and height without modifying the
resolution.

Try this:

library(raster)
library(rasterVis)

r <- raster()
r <- init(r, runif)

## res=72 if none is provided
png('smallFontSize.png', width=4000, height=4000)
levelplot(r)
dev.off()

png('correctFontSize.png', width=4000, height=4000, res=600)
levelplot(r)
dev.off()


Best,

Oscar.
