This function is essentially a simplified ; wrapper to the FSC_PSConfig object, which provides a powerful graphical user interface ; for configuring the IDL PostScript device. ; ; .. image:: psconfig.png ; ; :Categories: ; Utilities, Graphics ; ; :Returns: ; A structure of keywords, appropriate for configuring the PostScript device, is returned. ; These keywords are generally passed to the PostScript device by means of keyword inheritance:: ; ; keywords = PSConfig() ; Obtain PostScript keywords ; Set_Plot, 'PS' ; Select the PostScript device ; Device, _Extra=keywords ; Configure the PostScript device with keywords ; ; :Params: ; psobject: in, optional, type=object ; An FSC_PSCONFIG object reference of the sort returned by this function ; can be passed as an argument to the function. It is up to the user to destroy ; the object if passed as an argument. Passing an object argument essentially ; by-passes the rest of the keywords and the GUI will take its initial values ; from the values in the input object. This allows the programmer to keep track ; of how the user last configured the GUI and to set it up in exactly the same ; way the next time the GUI is invoked. ; ; :Keywords: ; AvantGarde: in, optional, type=boolean, default=0 ; Set this keyword to select the AvantGarde PostScript font. ; Bits_per_Pixel: in, optional, type=integer, default=8 ; The number of image bits saved for each image pixel: 2, 4, or 8. ; Bold: in, optional, type=boolean, default=0 ; Set this keyword to select a bold PostScript font. ; BookStyle: in, optional, type=boolean, default=0 ; Set this keyword to specify that the book version of the current PostScript ; font should be used. ; Bkman: in, optional, type=boolean, default=0 ; Set this keyword to select the Bookman PostScript font. ; Cancel: out, optional, type=boolean, default=0 ; If this keyword is set to 1, the user hit the Cancel button in the GUI. ; CMYK: in, optional, type=boolean, default=0 ; Set this keyword to use CMYK colors instead of RGB colors in the output. ; Color: in, optional, type=boolean, default=1 ; Set this keyword to 1 to select color or gray-scale output. ; Courier: in, optional, type=boolean, default=0 ; Set this keyword to select the Courier font. ; Debug: in, optional, type=boolean, default=0 ; Set this keyword to get traceback information when errors are encountered. ; Decomposed: in, optional, type=boolean, default=0 ; Set this keyword to turn on 24-bit color support. Set to zero to select indexed color ; support. Applies only to IDL versions 7.1 and higher. ; DefaultSetup: in, optional, type=structure ; Set this keyword to the "name" of a default style. Current styles (you can easily ; create and add your own to the source code) are the following:: ; "System (Portrait)" - The normal "default" system set-up. Also, "System". ; "System (Landcape)" - The normal "default" landscape system set-up. ; "Centered (Portrait)" - The window centered on the page. Also, "Center" or "Centered". ; "Centered (Landscape)" - The window centered on the landscape page. Also, "Landscape". ; "Square (Portrait)" - A square plot, centered on the page. ; "Square (Landscape)" - A square plot, centered on the landscape page. ; "Figure (Small)" - A small encapsulated figure size, centered on page. Also, "Encapsulated" or "Encapsulate". ; "Figure (Large)" - A larger encapsulated figure size, centered on page. Also, "Figure". ; "Color (Portrait)" - A "centered" plot, with color turned on. Also, "Color". ; "Color (Landscape)" - A "centered" landscape plot, with color turned on. ; Demi: in, optional, type=boolean, default=0 ; Set this keyword to select the Demi font style. ; Directory: in, optional, type=string ; Set this keyword to the name of the starting directory. The current directory is used by default. ; Encapsulated: in, optional, type=boolean, default=0 ; Set this keyword to 1 to select Encapsulated PostScript output. ; European: in, optional ; This keyword is depreciated in favor or `Metric`. ; Filename: in, optional, type=string, default='idl.ps' ; Set this keyword to the name of the PostScript file you wish to create. ; FontInfo: in, optional, type=boolean, default=0 ; Set this keyword if you wish to see font information in the GUI interface. Since font ; information has to be interpreted to be used, most users prefer not to see this information ; on the GUI. ; FontSize: in, optional, type=integer, default=12 ; Set this keyword to the desired font size. Values should be between 6 and 32. ; FontType: out, optional, type=integer ; This keyword is both an input and an output keyword. It allows you to specify the font ; type you wish to use, and it also returns the font type the user selected in the GUI. ; The user is responsibe for configuring the PostScript graphical commands with the appropriate font ; type, because it cannot be done via the normal Device keyword channel. Normally, this is set to ; !P.Font. ; Group_Leader: in, optional, type=long ; Set this keyword to the identifer of a widget group leader. This program will be destroyed ; if the group leader application is destroyed. ; Helvetica: in, optional, type=boolean, default=0 ; Set this keyword to select the Helvetica PostScript font. ; Inches: in, optional, type=boolean, default=1 ; Set this keyword to indicate sizes and offsets are in inches as opposed to centimeters. ; Set to zero by default if the `Metric` keyword is set. ; Italic: in, optional, type=boolean, default=0 ; Set this keyword to select italic type font styling. ; Isolatin: in, optional, type=boolean, default=0 ; Set this keyword to select ISOlatin1 encoding. ; Landscape: in, optional, type=boolean, default=0 ; Set this keyword to select Landscape page output.

Possible values are:: ; "Letter" - 8.5 by 11 inches. (Default, unless the Metric keyword is set.) ; "Legal" - 8.5 by 14 inches. ; "Ledger" - 11 by 17 inches. ; "A4" - 21.0 by 29.7 centimeters.

Set the name of the font ; with the `Set_Font` keyword. ; XOffset: in, optional, type=float ; Set this keyword to the X Offset. Uses "System (Portrait)" defaults. (Note: offset ; calculated from lower-left corner of page.) ; XSize: in, optional, type=float ; Set this keyword to the X size of the PostScript "window". Uses "System (Portrait)" defaults. ; YOffset: in, optional, type=float ; Set this keyword to the Y Offset. Uses "System (Portrait)" defaults.
