NAME: OS_INIT PURPOSE: Defines the structure of main operating system variables. All the operating system dependent varibles used in data catcher are assembled in this routine. CATEGORY: Global System Variables !os. CALLING SEQUENCE: OS_INIT PARAMETER FIELDS: ARCH: IDL detected operating system architecture OS: IDL detected operating system OS_FAMILY: IDL detected operating system family RELEASE: IDL release number FONT: Bold font used in highlight label in dialog DEVICE: Default output device FILE_SEP: Operating sytem file separator, '/' for unix '\' for W95 CHMOD: Command change file permission mode, 'chmod' MV: Command rename file, 'mv' for unix, 'rename' for W95 CP: Command copy file, 'cp' for unix, 'copy' for W95 RM: Command remove file, 'rm' for unix, 'del' for W95 LPR: Command print PS file, 'lpr' for unix, 'print' for W95 PRT: Command print text file, 'enscript' for unix, 'print' for W95 PRINTER: Default printer name, '' WC: Command return line count, 'wc' for unix COMMON BLOCKS: COMMON SYSTEM_BLOCK SIDE EFFECTS: This routine defines the OS_SYSTEM structure and the global system variable !os. All the system dependent varialbes used in data catcher and data viewer are kept in this routine. RESTRICTIONS: Current version works for Unix and W95 operating system. PROCEDURE: Porting to other operating system, the corresponding fields in 'os.init' may need to be modified accordingly. EXAMPLE: OS_INIT MODIFICATION HISTORY: Written by: Ben-chin K.

NAME: PS_CLOSE PURPOSE: This routine closes the PostScript output device and resets the the original system graphic device as the output plot device. CALLING SEQUENCE: PS_CLOSE INPUTS: None. OUTPUTS: None. KEYWORD PARAMETERS: None. COMMON BLOCKS: COMMON SYSTEM_BLOCK COMMON COLORS RESTRICTIONS: The program 'PS_open.pro' must be loaded into IDL prior calling this routine. EXAMPLE: PS_OPEN, 'myfile.ps' tvscl,scan PS_CLOSE MODIFICATION HISTORY: Written by: Ben-chin K. Cha, 03-23-95. 07-28-97 bkc Add the support for reverse PostScript color scheme. Add handling capability for different operating system

NAME: PS_ENSCRIPT PURPOSE: This routine uses the system printing command to print an ASCII text file. On unix operating system the command 'enscript -r' is used. CALLING SEQUENCE: PS_ENSCRIPT, 'filename' INPUTS: filename : Specifies the ASCII filename to be printed. OUTPUTS: A copy of the specified file is sent to the user selected printer. KEYWORD PARAMETERS: COMMON BLOCKS: COMMON SYSTEM_BLOCK RESTRICTIONS: The program 'PS_open.pro' must be loaded into IDL prior calling this routine. EXAMPLE: PS_ENSCRIPT, 'myfile' MODIFICATION HISTORY: Written by: Ben-chin K. Cha, 03-23-95. 07-28-97 bkc Add handling capability for different operating system

NAME: PS_OPEN PURPOSE: This routine sets the current graphics device to PostScript. and saves plot in a user specified PostScript file. CALLING SEQUENCE: PS_OPEN, 'myfile.ps' [,/TV] INPUTS: myfile.ps: Specifies the PostScript filename to be saved. OUTPUTS: The PostScript graphic output is saved which can be sent to any PostScript printer or viewer. KEYWORD PARAMETERS: TV: Specifies whether TV image plot to be used in PS. XOFFSET: Specifies xoffset in centimeter, default 1.905 YOFFSET: Specifies yoffset in centimeter, default 7. XSIZE: Specifies yoffset in centimeter, default 15 YSIZE: Specifies yoffset in centimeter, default 15 SCALE_FACTOR: Specifies scale factor, default 1 FONT: Specifies font string COMMON BLOCKS: COMMON PRINTER_BLOCK COMMON COLORS RESTRICTIONS: The program 'PS_open.pro' must be loaded into IDL first before calling this routine. EXAMPLE: PS_OPEN, 'myfile.ps' tvscl,image PS_CLOSE MODIFICATION HISTORY: Written by: Ben-chin K. Cha, 03-23-95. 07-28-97 bkc Add the support for color PostScript Add the support for reverse video Add handling capability for different operating system 05-15-98 bkc Change the reverse video to reverse legend color for 2D TV plot, to get reverse video use the xloadct's option, reverse feature 03-03-03 bkc add keyword xoffset,yoffset,xsize,ysize 05-19-04 bkc add keyword font string

NAME: PS_PRINT PURPOSE: This routine uses the system printing command to print a PostScript or ASCII text file. On the unix operating system the command 'lpr' is used. CALLING SEQUENCE: PS_PRINT, 'myfile.ps' INPUTS: myfile: Specifies either the PostScript or ASCII text filename to be printed. OUTPUTS: A copy of the specified file is sent to the user selected printer. KEYWORD PARAMETERS: COMMON BLOCKS: COMMON SYSTEM_BLOCK RESTRICTIONS: The program 'PS_open.pro' must be loaded into IDL prior calling this routine. EXAMPLE: PS_PRINT, 'myfile.ps' MODIFICATION HISTORY: Written by: Ben-chin K. Cha, 03-23-95. 07-28-97 bkc Add handling capability for different operating system 05-14-98 bkc Add the checking for unreadable color on the PS plot On unix if the color is too light use the gv to preview pops up setup printer and info dialog

NAME: PS_PRINTER PURPOSE: This widget dialog allows the user to set up PostScript printer and printer name to be used by the IDL session. Default setting is color PS using default printer. CATEGORY: Widgets. CALLING SEQUENCE: PS_PRINTER [,GROUP=Group] INPUTS: None. KEYWORD PARAMETERS: GROUP: The widget ID of the group leader of the widget. If this keyword is specified, the death of the group leader results in the death of PS_PRINTER. OUTPUTS: COMMON BLOCKS: COMMON PRINTER_BLOCK SIDE EFFECTS: Initially the system printer is set to the user's default printer. If a null printer name is specified, whatever the system printer was previously set will be used. RESTRICTIONS: The program 'PS_open.pro' must be loaded into IDL prior calling this routine. PROCEDURE: EXAMPLE: PS_PRINTER MODIFICATION HISTORY: Written by: Ben-chin K. Cha, 6-01-97. 10-15-97 bkc - Add droplist Y/N for reverse color option Now it defaults to non reverse color option. 05-14-98 bkc - Remove the B/W option, use the xloadct to select B/W Change reverse video to reverse legeng color if legend is in white color
