R devel - Apr 2005 - inconsistent fonts generated in postscript file (PR#7795)

Full_Name: Xiang Li
Version: 2.01
OS: WinXP
Submission from: (NULL) (128.248.174.125)


I am trying to use the font of "TT Courier New: bold" to get the equal
size of
letters. The "TT Courier New: bold" is the 11th font listed in the
Rdevga file.

You can just try a simple case:

plot(1:10, 1:10, xlab = "XILMV", font.lab = 11)

I save the plot in postscript format, and found the font in .ps file becomes
Arial font. While I save the plot in JPEG or PNG format, everything is correct.

Best

Xiang

Please DO READ the documentation.

Rdevga applies to *windows* devices: see its help page.
On Windows, saving to JPEG or PNG is using a windows device.

The way fonts are chosen in postscript() is described on its help page. It 
is *definitely* using not Arial but Helvetica, even though your viewer 
might do a substitution.

There is a section in the FAQ on BUGS.  Had you read it, you could have 
avoided wasting our time.  Or even if you had read ?postscript.

It's not a device independent font so you cannot expect it to be
copied between devices. Look at the help page for postscript().
