; Converts a PostScript file to a PDF file. This program requires
; the `Ghostscript <http://www.ghostscript.com/download/>` program
; to be installed on the user's computer, unless you are using a
; Macintosh computer or an alterntive UNIX command to do the conversion
; for you. If you are on a Macintosh, the supplied pstopdf
; program is used instead. Use the `UNIX_Convert_Cmd` keyword to select
; an alternative UNIX command (e.g., pstopdf or epstopdf).
;
; The program requires the `Coyote Library <http://www.idlcoyote.com/documents/programs.php>`
; to be installed on your machine.
;
; :Categories:
; Utilities, Graphics
;
; :Params:
; ps_file: in, required, type=string
; The name of the input PostScript file that is being converted to a PDF file.
; If not provided, the user will be asked to select a file.
; pdf_file: in, optional, type=string
; The name of the output PDF file. If not provided, the name is constructed from
; the input PostScript file name.
;
; :Keywords:
; delete_ps: in, optional, type=boolean, default=0
; If this keyword is set, the PostScript file will be deleted after conversion.
; gs_path: in, optional, type=string
; This program assumes that UNIX users can access Ghostscript with the "gs"
; command. It assumes WINDOWS users have installed Ghostscript in either
; the C:\gs or C:\Program Files\gs directories. If either of these assumptions
; is incorrect, you can specify the directory where the Ghostscript executable
; resides with this keyword. (The Windows 32-bit executable is named gswin32c.exe
; and the 64-bit executable is named gswin64c.exe.)
; pagetype: in, optional, type=string, default="LETTER"
; Set this keyword to the "type" of page. Possible values are::
;
; "Letter" - 8.5 by 11 inches.
; "Legal" - 8.5 by 14 inches.
; "Ledger" - 11 by 17 inches.
; "A4" - 21.0 by 29.7 centimeters.
;
; showcmd: in, optional, type=boolean, default=0
; Set this keyword to print the command that is spawned in the command output window.
; silent: in, optional, type=boolean, default=0
; Set this keyword to suppress output messages.
; success: out, optional, type=boolean
; Set this keyword to a named variable that on output will contain a 1 to
; indicate successful completion of the command, or to 0 otherwise.
; unix_convert_cmd: in, optional, type=string
; There are a number of commands on UNIX machines for converting PostScript files
; to PDF files. This program assumes you are using Ghostscript to do the conversion
; for you. The Ghostscript command on most UNIX machines is "gs", which is used if
; this keyword is undefined. However, if you would prefer to use another program to do
; the conversion for you, you can specify the name of the command here. For example,
; "pstopdf" or "epstopdf". In creating the actual command, this command will be
; separated by a space from the input file name. In other words, if the alternative
; conversion command was "pstopdf", the actual command would be "pstopdf" + " " + ps_file.
; Any output filename is ignored. This command does not apply to Macintosh or Windows
; computers.
; version: out, optional, type=string
; On exit, contains the version of Ghostscipt that was used. Not available on Macs
; or if an alternative UNIX command was used.
;
; :Examples:
; A typical sequence of commands to create a test.pdf file::
;
; cgPS_Open, Filename='test.ps'
; cgHistoplot, cgDemoData(7), /Fill
; cgPS_Close
; cgPS2PDF, 'test.ps'

; :History:
; Change History::
; Written, 6 December 2011, from code supplied to me by Paul Krummel. DWF.
; I had been using the Mac command pstopdf to create PDF files on Macs. Unfortunately, these
; PDF files are rotated incorrectly for plots having a landscape aspect ratio (ie, most plots).
; In this version of the software, I have decided to have Macs use Ghostscript and ImageMagick
; like all other UNIX machines. However, I have left the pstopdf code in place to accommodate
; anyone who prefers that method. You will have to uncomment the appropriate bits of code
; (there are two places where this has to happen, search for "DARWIN" in the code). 14 Aug 2013. DWF.
