if (canvOK==1)
{
var ctx=c.getContext("2d");
ctx.fillStyle="#FF0000";
ctx.fillRect(20,20,100,50);

var grd=ctx.createLinearGradient(140,20,240,70);
grd.addColorStop(0,"black");
grd.addColorStop(1,"white");
ctx.fillStyle=grd;
ctx.fillRect(140,20,100,50);

var grd2=ctx.createLinearGradient(20,90,120,90);
grd2.addColorStop(0,"black");
grd2.addColorStop("0.3","magenta");
grd2.addColorStop("0.5","blue");
grd2.addColorStop("0.6","green");
grd2.addColorStop("0.8","yellow");
grd2.addColorStop(1,"red");
ctx.fillStyle=grd2;
ctx.fillRect(20,90,100,50);

ctx.font="30px Verdana";
var grd3=ctx.createLinearGradient(140,20,240,90);
grd3.addColorStop(0,"black");
grd3.addColorStop("0.3","magenta");
grd3.addColorStop("0.6","blue");
grd3.addColorStop("0.8","green");
grd3.addColorStop(1,"red");
ctx.strokeStyle=grd3;
ctx.strokeText("Smile!",140,120); }
