I have a simple fuction which fills the drawn image if the user chooses to
canvas.on('mouse:up', function() {
if(main.mode == 'fill') {
var object = main.canvas.item(main.canvas.getObjects().length-1);
object.fill = main.pColor();
canvas.renderAll();
}
})
this works fine for solid(opacity 1) colors. When using a color with less opacity:
It seems the stoke and fill overlap yielding a darker line.
I experimented with globalCompositeOperation. I am thinking eliminate the stroke or set the stroke opacity to zero. I hope there is a better answer.
I tried a few approaches: setting stroke opacity to zero and trying to get rid of the stroke altogether.
what works best is adding
object.set('strokeWidth', 0);
to the handler above.
set ensures the canvas will be updated.
It is working well.
