[ncl-talk] Image Resizing Issue

[Rick Brownrigg]

Hi all,

I certainly appreciate Sudipta's participation here, but this would not
work:

wks = gsn_open_wks(wks_type,"test")
  wks at wkWidth = 2500
  wks at wkHeight = 2500

For various esoteric reasons, the resources have to specified at the time
the workstation is created, and the correct form is (oddly enough), what
Kerwyn originally had:

wks_type = "png"
wks_type at wkWidth = 2500
wks_type at wkHeight = 2500
wks = gsn_open_wks(wks_type, "test")

However, the error messages being reported do not make sense in this
context, and I agree with Sudipta that there must be something else going
on on the script, and perhaps the whole thing could be posted.

Here's a simple script from our examples that demonstrates this:

begin

  a = addfile("$NCARG_ROOT/lib/ncarg/data/cdf/uv300.nc","r")

  u = a->U(0,:,:)


  wks_type = "png"

  wks_type at wkWidth = 2500

  wks_type at wkHeight = 2500

  wks = gsn_open_wks(wks_type,"gsn_xy")

  ;;These do not work; uncomment and comment out the wks_type@ versions
above to demonstrate

  ;wks at wkWidth = 2500

  ;wks at wkHeight = 2500


  res                        = True                        ; plot mods
desired

  res at tiYAxisString          = u at long_name + " "+u at units   ; add units to
title

  res at tiMainString          = "Example of gsn_y"      ; title

  plot=gsn_y(wks,u(:,30),res)


end

Hope this helps...
Rick
