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 [].
