how to change the page size of pdf?

hi,

I need to make a 1x2 panel plot and insert the plot into my
LaTeX file using a "landscape" orientation. Obviously, a 1x2 panel plot
will not fit in an A4 paper (the 1x2 plot is quite short. There is too much
blank above and below the plot).

So I want to change the page size of the output PDF to fit a 1x2 panel
correctly. However, there is no change in the output.
My corresponding codes are as follows:

...
...
...
wks = gsn_open_wks("pdf", "test")

res_at_gsnDraw = False
res_at_gsnFrame = False

plot1 = gsn_csm_contour_map(wks, T(1,:,:),res)
plot2 = gsn_csm_contour_map(wks, T(2,:,:),res)

a4_height = 29.7
a4_width = 10 ; make it a little narrow
cm_per_inch = 2.54
panelres = True
panelres_at_gsnPaperWidth = a4_width/cm_per_inch
panelres_at_gsnPaperHeight = a4_height/cm_per_inch
panelres_at_gsneaperMargin = 0.1
panelres_at_gsnMaximize = True
panelres_at_gsnPaperOrientation = "landscape"
gsn_panel(wks, (/plot1, plot2/),(/1,2/), panelres)
...

The PDF has been created but when I browse it with Acrobat Reader,
the page is still a 21cmx27cm one. And there is still too much
blank in either vertical side.

I think this should be a common problem when one try
to insert NCL plot into a document (ie TeX one)
Can this page size be changed?

Thank you very much!
