Description

If a graphic window pixmap property is “on” the drawings are send to a pixmap memory instead of the screen display.

The show_pixmap() instruction send the pixmap to the screen.

The pixmap mode can be used to obtain smooth animations. This property can be found among the figure entity fields (see `figure_properties`_).

WARNING: This function is obsolete from Scilab 5.4.0 and is going to be removed with Scilab 5.4.1 Please use `drawlater`_/`drawnow`_ instead.

Examples

f=`gcf`_();
f.pixmap='on'; //set the pixmap mode
a=`gca`_();
a.data_bounds=[0 0; 10 10];
//construct two rectangles
`xrects`_([0;10;1;1],5);
r1=`gce`_();
r1=r1.children;
`xrects`_([0;1;1;1],13);
r2=`gce`_();
r2=r2.children;
//animation loop
for k=1:1000
  //draw the rectangles in the pixmap buffer
  `move`_(r1,[0.01,-0.01]);
  `move`_(r2,[0.01,0.01])
  //show the pixmap buffer
  show_pixmap()
  `xpause`_(10000)
