xget Scilab Group Scilab Function xget
NAME
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=xset("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 This keyword is obsolete, please use xget("color") or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",x,y);
: Get the position of the upper left point of the graphics window
pos=[x,y].
