Scilab Function

xget - get current values of the graphics context

### Calling Sequence

  `[x1]=xget(str,[flag])`
  `xget()`

### Parameters

- `str` : string.
- `flag` : optional. Set to 1 gives a verbose mode.

### Description

This function is used to get values from the graphics context on the topic specified by the string `str` . When called with no argument, a choice menu is created showing the current values and changes can be performed through toggle buttons.

  number=xget("alufunction"): Get the logical function number used for drawing. See `xset` .
  str=xget("auto clear"): Get the auto clear status (`"on"` or `"off"` ).
  color=xget("background"): Get the background color of the current graphics window.
  rect=xget("clipping"): Get the clipping zone as a rectangle rect=[x,y,w,h] (Upper-Left point Width Height).
  c=xget("color"): Get the default color for filling, line or text drawing functions. `c` is an integer projected in the interval [0,whiteid]. 0 stands for black filling and whiteid for white. The value of whiteid can be obtained with `xget("white")` .
  cmap=xget("colormap"): Get the colormap used for the current graphics window as a m x 3 RGB matrix.
  dash=xget("dashes"): Get the dash style dash=[dash_number] where dash_number is the id of the dash. This keyword is obsolete, please use `xget("color")` or `xget("line style")` instead.
  font=xget("font"): Get font=[fontid,fontsize], the default font and the default size for fonts. size.
  fontsize=xget("font size"): Get the default size for fonts size.
  color=xget("foreground"): Get the foreground color of the current graphics window.
  str=xget("fpf"): Get the floating point format for number display in contour functions. Note that `str` is `""` when default format is used.
  color=xget("hidden3d"): Get the color number for hidden faces in plot3d.
  pat=xget("lastpattern"): Get the id of the last available pattern or color, with the current colormap of the current window. In fact `pat+1` and `pat+2` are also available and stand respectively for black and white pattern.
  type=xget("line mode"): Get the line drawing mode. type=1 is absolute mode and type=0 is relative mode. (Warning: the mode type=0 is has bugs)
  xget("line style"): Get the default line style (1: solid, >1 for dashed lines).
  mark=xget("mark"): Get the default mark id and the default marks size. `mark=[markid,marksize]` .
  marksize=xget("mark size"): Get the default marks size.
  pat=xget("pattern"): Get the current pattern or the current color. `pat` is an integer in the range `[1,last]` . When one uses black and white, 0 is used for black filling and `last` for white. The value of `last` can be obtained with `xget("lastpattern")` .
  value=xget("thickness"): Get the thickness of lines in pixel (0 and 1 have the same meaning: 1 pixel thick).
  flag=xget("use color"): Get the flag 0 (use black and white) or 1 (use colors). See `xset` .
  [x,y]=xget("viewport"): Get the current postion of the visible part of graphics in the panner.
  dim=xget("wdim"): Get the width and the height of the current graphics window dim=[width,height].
  win=xget("window"): Get the current window number `win` .
  pos=xget("wpos");: Get the position of the upper left point of the graphics window pos=[x,y].
