5 The IntPic package options.
  
  
  5.1 Available options
  
  The  list  of  allowed  options,  some  of  which  already familiar from the
  examples, can be obtained as follows:
  
    Example  
    gap> RecNames(IP_TikzDefaultOptionsForArraysOfIntegers);
    [ "other", "colors", "highlights", "shape_only", "colsep", "rowsep", 
      "cell_width", "allow_adjust_cell_width", "scale", "inner_sep", 
      "line_width", "line_color" ]
  
  
  Its meaning is as follows:
  
      colors: any list of colors (to be used with the LaTeX package xcolor)
  
      highlights:  a  list of lists of integers -- the elements of the first
        are  colored  by using the first color, etc. In cases of elements that
        appear in more than one list a kind of gradient (made with 4 colors at
        most) is used to fill the cell; the number may be printed with a fifth
        color and a sixt color may be used for the border.
  
      shape_only:  an  option  to  be used when only the shape is important.
        When true or " " is used, all the nodes are empty; using a symbol, for
        instance a *, this symbol is printed in all the nodes.
  
      colsep: the tikz matrix option column sep
  
      rowsep: the tikz matrix option row sep
  
      cell_width: the tikz matrix option minimum width
  
      scale: the tikz matrix option scale
  
      inner_sep: the tikz matrix option inner sep
  
      line_width: the tikz matrix option line width
  
      line_color:  the  tikz matrix option line color: the color of the cell
        borders
  
      allow_adjust_cell_width:  the  number  of  points  per digit (to avoid
        discrepancies  between  the  width of the cells when there are numbers
        with different number of digits to be printed). When the user sets the
        option  cell_width,  then allow_adjust_cell_width is automatically set
        to false
  
      other:  if non empty, the complete tikz code has to be written (it may
        be useful when several images are to be produced - otherwise, changing
        the tikz code would be enough)
  
          Example  
          other := ["\\draw[postaction={draw,line width=1pt,red}] (-80pt,-8pt) 
          rectangle (16pt,40pt);","\\draw[postaction={draw,line width=1pt,blue}] 
          (-16pt,8pt) rectangle (80pt,-40pt);"]
        
  
  Adding  this  option  to  one  of  the  preceding  examples, one obtains the
  following:
  
  
  5.2 Default options
  
  The defaults for the available options are as follows
  
      colors: ShuffledIP_colors
  
      highlights: [[]]
  
      shape_only : "false"
  
      colsep: "2"
  
      rowsep: "2"

          "black!40", "black!10" ], colsep := "2", highlights := [ [  ] ], 
      inner_sep := "3", line_color := "black", line_width := "1", other := [  ], 
      rowsep := "2", scale := "1", shape_only := "false" )
    
            
  
  
  The  user  may want to change the defaults by editing the file options.gd in
  the folder gap. The changes are lost whenever any re-installation occurs. It
  is  recommended  that  in  this  case  a  copy  is  made, although it is not
  guaranteed that it will work in the next release.
