**CIGAL Reference Manual, Chapter 6 (RealTime): r_picture**
===== r_picture -- Transfer a picture to the screen =====
**usage:     r_picture opflg eflag ltime   PictData [Flag Pos]**

If PICTDATA is a character string, it is taken to be the name of a
picture file (PICT, TIFF, or PCX formats). If PICTDATA is an image
list, it should contain the picture data, the filename, or both
(see [[jvs:cigal:manual:chapter2:addlist|ADDLIST(2)]]).
The POS argument indicates where on the screen to put the picture.

The FLAG argument is a bitflag with the following meanings:
          1 - center the picture (otherwise POS marks upper left corner)
                If POS is a rectangle (XDIM == 4), center in the box
                    If POS is a point (XDIM == 2), center at that point
                    If POS is empty or omitted, center on the screen
          2 - just ensure that the data is in memory; if not, read it from
              the disk file. This only works if PICTDATA is an image list.
          4 - scale the image to fit the POS rectangle (if possible)

FLAG defaults to 0 if POS is specified, or 1 otherwise.
