Hi,
I m working on R and read one image with russian font using readjpeg()
function and write it on pdf (using grid). But russian text is not
visible
on pdf. How can i fix my pblm?
You are working with two different plotting paradigms. pdf and ps are
vector formats and do encode the text as individual characters. But
jpeg is a lossy bitmap format, so text is not separately encoded as
characters.

There is a package named 'jpeg" so I'm wondering if you are unaware
the case in naming objects in R is enforced?

pdf("out.pdf" , width = 6.6 ,height = 4.2,family= "URWHelvetica",

grid.newpage()
pushViewport(viewport(width=0.9, height=0.9))

width=0.15,
height=1.0, just=c("left", "bottom")))
grid.raster(a, y=unit(ypos.img, "native"))
popViewport()
popViewport()
dev.off()
