XPRINT

Name


      XPRINT

Purpose


      Print text on graphics device. After initializing use just like print.

Category


Calling Sequence


      xprint, item1, [item2, ..., item10]

Inputs


      txt = text string to print. in

Keyword Parameters


Keywords


        COLOR=c set text color.
        ALIGNMENT=a set text alignment.
        /INIT to initialize xprint.
          xprint,/INIT,x,y
            x,y = coord. of upper-left corner of first line of text. in
        /DATA use data coordinates (def). Only needed on /INIT.
        /DEVICE use device coordinates. Only needed on /INIT.
        /NORM use normalized coordinates. Only needed on /INIT.
        /NWIN use normalized window coordinates. Only needed
          on /INIT. NWIN coordinates are linear 0 to 1
          inside plot window (inside axes box).
        CHARSIZE=sz Text size to use. On /INIT only.
        CHARTHICK=thk Text thickness to use. On /INIT only.
          Text is thickened by shifting and overplotting.
          Thk is total number of overplots wanted. To shift by
          > 1 pixel per plot do CHARTHICK=[thk,step]
          where step is in pixels (def=1).
        DY=factor. Adjust auto line space by this factor. On /INIT only
          Try DY=1.5 for PS plots with the printer fonts (not PSINIT,/VECT).
        YSPACE=out return line spacing in Y.
        x0=x0 return graphics x-position of text in normalized coordinates.
        y0=y0 return graphics y-position of text in normalized coordinates.

Outputs


Common Blocks


      xprint_com

Notes


      Notes: Initialization sets text starting location and text size.
        All following xprint calls work just like print normally does except
        text is output on the graphics device.

Modification History


      R. Sterner, 9 Oct, 1989.
      H. Cohl, 19 Jun, 1991. (x0, y0)
      R. Sterner, 25 Sep, 1991 --- fixed a bug that made line spacing
      wrong when the window Y size varied from the normal value. The
      bug showed up for psinit,/full with !p.multi=[0,1,2,0,0] where
      the line spacing appeared to be 2 times too much. Was using
      xyouts to print a dummy letter to get its size. Now just use
      the value !d.y_ch_size (dev coord) as a good guess.
      R. Sterner, 10 Mar, 1992 --- added CHARTHICK.
      R. Sterner, 18 Mar, 1992 --- Modified CHARTHICK to do shifted
      overplots and added shift size in pixels.
      R. Sterner, 27 Mar, 1992 --- fixed a bug added with the modified
      CHARTHICK.
      R. Sterner, 20 May, 1993 --- Allowed CHARSIZE.
      R. Sterner, 30 Jul, 1993 --- coordinate system used only to set
      initial point, not needed for each print.
      Handle log axes.
      R. Sterner, 2010 May 04 --- Converted arrays from () to [].
