Hi there,
I am a Chinese R user. I hope to display Chinese character in a plot,
and than save it in PostScript format. I have read the article titled
"Non-Standard Fonts in PostScript and PDF Graphics", especially the
section about CJK fonts. I also tried the code:
pdf("chinese.pdf", width=3, height=1)
grid.text("\u4F60\u597D", y=2/3, gp=gpar(fontfamily="CNS1"))
grid.text("is 'hello' in (Traditional) Chinese", y=1/3)
dev.off()
however, it's not valid with postscript(). It seems that postscript()
need to set family in postscirpt(..., family = "CNS1"). Then all the
characters are in CJK font, and it's not what I hope to get. I hope the
Latin character is displayed in Helvetica.
Any suggestions? Thanks in advance!
Try this ...
# Use "Helvetica" as default, but include "CNS1" as a font that
# will be used somewhere within the file
postscript("chinese.pdf", width=3, height=1, fonts="CNS1")
grid.text("\u4F60\u597D", y=2/3, gp=gpar(fontfamily="CNS1"))
grid.text("is 'hello' in (Traditional) Chinese", y=1/3)
dev.off()
That doesn't work for me using the ancient version of R (a year old)
on this box. It produces a file that looks like a postscript file,
but which is slightly smaller than the one that a call to pdf() makes
but cannot be displayed by any file viewer I have.
The filename in Paul's code is "chinese.pdf". In fact, it's a postscript
file for it was created by postscript(). If your system dose not have
the specific font and corresponding cidfmap (from ghostscript
distribution), the file cannot be displayed.
However, it kind of works if I convert the pdf file into a postscript
file using pdftops, but I doubt that's what Jinsong wanted. It's
35Mb!
I try to convert the "chinese.pdf" to postscript file using pdftops,
however, I get the following error:
Error: May not be a PDF file (continuing anyway)
Error (0): PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table
So would you like to send the file to me?
Perhaps it really does work using a more up to date version.
Regards,
Jinsong
