CGPS2PDF
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).

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::
PS_Start, Filename='test.ps'
cgHistoplot, cgDemoData(7), /Fill
PS_End
cgPS2PDF, 'test.ps'
