xplot84driver (CCP4: Supported Program)

NAME

   xplot84driver - X-windows tool, a viewer for Plot84 meta files.

SYNOPSIS

   xplot84driver plot84_meta_file

DESCRIPTION

   xplot84driver belongs to the XCCPJiffy class of simple X11 graphic
   based programs. xplot84driver reads a Plot84 Metafile, recognises
   pictures and interprets them.

   xplot84driver uses an X-Windows device and has an option to create
   a PostScript file.

   Running the program xplot84driver creates a Header window with
   boxes showing:

   Quit
          to exit the program

   (unnamed)
          box containing current Plot84 meta file name

   List of Pictures
          A list of the pictures stored within the Plot84 metafile.
          Select the picture to view with the Left Mouse Button. This
          generates the view window and QUIT in that window closes the
          window. PLOT creates a PostScript version. (If you want a
          file then go to the CONTROL panel first.)

   Control Panel
          Clicking the Left Mouse button here allows one to toggle
          between Portrait and Landscape for the output Postscript
          file conversion and the option to specify a Output File for
          the Postscript file. The Print command is controlled by the
          XCCPJiffy*psPlotCommand resource. The Quit button exits the
          control panel.

NOTE ON COLOURS AND LINE STYLES - For Users and Programmers

   Where a program allows a user to specify colours in numbers (for
   example PLUTO), then the user should be aware of the mapping of
   colour  numbers  to  real colours and to line properties of a
   black/white PostScript Laser printer. These are controlled via the
   entries in the X-resource database.

   xplot84driver works in colour/linewidth graphic mode, i.e. maps
   colour numbers given by plot84 file contents to real colours for X
   graphics and Postscript line attributes. Currently 10 colours are
   available.

   X colours, Postscript line attributes and width are controlled via
   the  entries  in  X-resource  database  (see X manual). It is
   recommended to load X-resources into the X-server database (xrdb).
   Once the database is loaded, one can optimise it using xrdb to
   load/merge a personalised set of X-Application Resources.

   X mapping is controlled by:
XCCPJiffy.plot84Picture*draw2d.background:      white
XCCPJiffy.plot84Picture*draw2d.color1:          black
   .
   .
   .
XCCPJiffy.plot84Picture*draw2d.col or10:         indigo
Line width is interpreted directly.

   Postscript mapping is controlled by:
XCCPJiffy*psColor1:     1 setlinejoin [] 0 setdash
   .
   .
   .
XCCPJiffy*psColor10:    1 setlinejoin [8 1] 0 setdash
Line width is calculated as:
   value from plot84matefile * XCCPJiffy*psBasicLineWidth resource

   To check your current setting use for instance
   xrdb -query | grep XCCPJiffy | more
