Mike,
If you are using the Low Level Utilities (traditional Fortran
and C subroutine libraries), the item that controls the output
workstation is the argument WKTYPE in the GKS open workstation
subroutine, GOPWK(WKID,CONID,WKTYPE)
The choice of this argument is documented in the GKS User Guide
at URL
http://ngwww.ucar.edu/ngdoc/ng4.0.1/gks/ps.html
In the new interfaces
=====================
If you are using High Level Utilites or ncl, then you need
to open a Workstation object and set the resource wkPSFormat
to "ps", "eps", or "epsi" as documented at location:
http://ngwww.ucar.edu/ngdoc/ng4.0.1/ref/hlu/obj/PSWorkstation.res.html#wkPSFormat
An example program which shows how to create a workstation object
in NCGM, X11, or PostScript is given at location:
http://ngwww.ucar.edu/ngdoc/ng4.0.1/qsg/basic/basic07.html
The HLU Fortran example is basic07f.f, the C example is
basic07c.c, and the NCL example is basic07n.ncl.
You can run any of these three examples by typing:
ng4ex basic07f.f
or ng4ex basic07c.c
or ng4ex basic07n.ncl
The examples create straight PostScript. To switch to eps, or epsi
Fortran HLU
-----------
In the section of code of example basic07f.f:
---------------------------------------------------------------------
C
C Create a PostScript workstation.
C
call NhlFRLClear(srlist)
call NhlFRLSetString(srlist,'wkPSFileName','basic07f.ps',ierr)
^^^^^^^^^^^
(change the above to basic07f.eps or basic07f.epsi)
call NhlFRLSetString(srlist,'wkOrientation','portrait',ierr)
call NhlFRLSetString(srlist,'wkPSFormat','ps',ierr)
^^
(change the above to eps, or epsi)
call NhlFCreate(widp,'basic07ps',NhlFPSWorkstationClass,0,
1 srlist,ierr)
---------------------------------------------------------------------
C HLU
-----
In the section of code of example basic07c.c:
---------------------------------------------------------------------
/*
* Create a PostScript workstation.
*/
NhlRLClear(srlist);
NhlRLSetString(srlist,NhlNwkPSFileName,"basic07c.ps");
^^^^^^^^^^^
(change the above to basic07c.eps or basic07c.epsi)
NhlRLSetString(srlist,NhlNwkOrientation,"portrait");
NhlRLSetString(srlist,NhlNwkPSFormat,"ps");
^^
(change the above to eps, or epsi)
NhlCreate(&widp,"basic07ps",NhlpsWorkstationClass,NhlDEFAULT_APP,
srlist);
------------------------------------------------------------------------
NCL
---
In the section of code in example basic07n.ncl:
------------------------------------------------------------------------
;
; Create a PostScript workstation.
;
widp = create "basic07ps" psWorkstationClass defaultapp
"wkPSFileName": "basic07n.ps"
^^^^^^^^^^^
(change the above to basic07n.eps or basic07n.epsi)
"wkOrientation": "portrait"
"wkPSFormat": "ps"
^^
(change the above to eps, or epsi)
end create
------------------------------------------------------------------------
Please let me know which interface you are using!
