[ncl-talk] How to use the wkPDFResolution resource?

[yinjinfang88 at 163.com]

Dear all,
      I am just trying to use the wkPDFResolution resource to increase the PDF figure resolution. Two ways have been tested, but it does not work. The NCL is version 6.3.0. 

One way to set a value for the wkPDFResolution is :

 type = "pdf"
 type at wkPSResolution = 5400;   (default is 1800)
 wks = gsn_open_wks(type, "54511")

However,  a warning is given
warning:wkPSResolution is not a resource in the given object
The warning indicates that the wkPSResolution resource is unavailable at this time.

Alternative way is using a gsun to open a workstation.
xworkid = create "testWork" pdfWorkstationClass defaultapp 
"wkPDFResolution" : 5400 
"wkPDFFileName" : "test.pdf" 
end create 

This setting works well. However, the size of the pdf file remains unchanged.

Any idea? 
Thanks a lot.
