show_pixmap

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).

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()
end
